'I Could Trust It': Experiences of Reciprocal Translocation Carriers and Their Partners With Prenatal Cell-Free DNA Screening for Unbalanced Translocations.

To explore the experiences of people having cfDNA screening to detect unbalanced translocations, and to understand motivations for choosing this option. We used a qualitative approach with in-depth semi-structured interviews with reciprocal translocation carriers and their partners. People who underwent cfDNA screening with translocation analysis through Victorian Clinical Genetics Services between 2015 and 2019 were invited to take part. Purposive sampling based on the participant's geographic location, requesting practitioner specialty and cfDNA screening result was used to capture a range of experiences. Interview transcripts were analysed using thematic analysis. Participants (n=13) had complex reproductive journeys associated with the translocation and opted for cfDNA screening rather than prenatal diagnosis to avoid risk to their pregnancy. Participants benefited from having a result early in pregnancy and had sufficient confidence in the result to decline a diagnostic testing procedure. Participants' experiences with cfDNA screening were intertwined with the experience of being a carrier of a reciprocal translocation. cfDNA screening with translocation analysis was perceived as an acceptable alternative to prenatal diagnosis and should be made more accessible to balanced translocation carriers. Access to specialist genetic counselling services is needed to ensure couples are provided with information about all prenatal testing options, including the benefits and limitations associated with cfDNA screening with translocation analysis.

Feasibility of an environmental scan-based approach to collecting information about factors impacting cancer genetics services in Latin American countries.

Clinical cancer genetics services are expanding globally, but national policy and health care systems influence availability and implementation. Understanding the environmental factors within a country is required to appropriately implement, adapt, and evaluate cancer genetics service delivery models. An environmental scan (ES) is an approach used in business, public health, health care and other sectors to collect information about an environment or system for strategic decision making and program planning. An ES has been previously used to assess cancer genetics clinic-level factors to inform quality improvement efforts in the United States. We assessed the feasibility of using an ES to collect information about factors that may influence cancer genetics service delivery in the outer-most socio-ecological model environmental levels (policy, national agencies, healthcare systems, cultural considerations) in three Latin American countries. Oncology and Genetics care team members at three participating sites used publicly available sources and personal experiences to complete a data collection form (DCF) that included questions about subtopics: laws and policies, relevant agencies and regulations, health care systems and insurance, and cultural considerations. Time to complete the DCF and DCF completeness were used to measure ES feasibility. Participating sites completed the DCF in 3 months, and most questions (average, 87.0%) were answered. Questions in the cultural considerations subtopic had the fewest answers (average, 77.8%). Overall, the ES was feasible and identified a lack of published literature related to cultural considerations impacting health care and genetics services uptake in Latin America. Environmental factors impact cancer genetics services, and identification of these factors will facilitate future collaborative research and genetics service delivery dissemination efforts.

The implementation and outcome of a breast cancer genetic counselling service at Potchefstroom Hospital: a model for outreach

Aim Breast cancer is the most prevalent cancer in South African females, making up 27.1% of all histologically diagnosed cancers in 2020. Although genetic technology and awareness of genetic counselling have improved, genetic counselling services in South Africa remain largely inaccessible. Clinical genetic services are only formally available in four South African provinces and few outreach programmes exist for small towns and cities. Until 2019, genetic counselling services were unavailable in the North West province; however, since then, genetic counsellors from the National Health Laboratory Service and the University of the Witwatersrand have provided genetic counselling services to patients at the Breast Clinic at Potchefstroom Hospital regularly each year. Method The aim of this pilot study was to perform a retrospective file review and report on the implementation and outcomes of the genetic counselling service at the Breast Clinic at Potchefstroom Hospital, from its inception in 2019, until November 2022. Fifty-two patients attended a genetic counselling consultation during that period. Results The majority of patients (83.7%) were diagnosed with an invasive ductal carcinoma, and 57.7% of the patients had a family history of cancer. A total of 62.8% of patients had a histologic grade 3 tumour. A total of 25.5% (12/47) of patients tested positive for a pathogenic variant in BRCA1 or BRCA2. A total of 45 at-risk first-degree relatives were identified who could benefit from predictive testing. Conclusions This study highlights the benefit of offering clinical genetics services through outreach clinics. Being able to offer this service is not only beneficial for the management of the affected individuals, but also for their at-risk relatives. The initiative serves as a positive example of how limited resources can be extended to benefit patients.

Genetic counseling development and milestone in Oman

Genetic counseling as an emerging profession has seen an expansion around the world. In the Sultanate of Oman, the profession has developed with the establishment of clinical and biochemical genetic services in 2010 and genetic counseling services in 2011. Currently, three main genetic counseling teams serve the country through qualified genetic counselors who completed internationally-recognized MSc program. The genetic counselors are working in governmental clinical genetic units and play vital roles in enhancing the quality of genetic services dealing with pediatric and adult-onset disorders. The impact of the service is reflected in the escalated demand for preventative measures such as alternative reproductive options, premarital genetic counseling and testing as well as predictive counseling and testing. Despite the limited resources and absence of a licensing body, the genetic counseling profession in Oman is progressing. This special report describes the development of genetic counseling in Oman and the milestones reached. It details the areas of service, scope of practice, and the unique social and cultural nuances inherent to genetic counseling in Oman.

Becoming agents for genomic change: genetic counsellors' views of patient care and implementation influences when genomics is mainstreamed.

Genetic counsellors (GCs) across the world are increasingly transitioning beyond clinical genetics services to meet the growing demands for genomic healthcare. This presents a unique opportunity for GCs to be 'genomic change agents' as they work in alternative models of care. Through various innovative models of mainstream care funded through a change program, we explored the views of GCs regarding their position as 'genomic change agents' and what may hinder or drive the success of their evolving roles. Guided by the Diffusion of Innovation Theory, we conducted qualitative interviews with all twelve GCs employed by the change program in different models of providing genomics across five specialties in Australia. Audio-recordings of all interviews were transcribed verbatim and analysed using inductive content analysis. Findings show that early in these new roles, participants held varied descriptions of 'genomics mainstreaming': some envisioned it as an end state exclusive to medical specialists practicing genomics while others saw the involvement of GCs as crucial. Participants believed they were uniquely positioned to expedite patient access to genomic testing and counselling and enhance medical specialists' capability to use genomics. Challenges included hesitancy of some medical specialists regarding the value of genomics in healthcare and potential tension arising from distinct perspectives and practice between genetic and non-genetic professionals. Participants anticipated a decline in the standard of care when non-genetic colleagues managed consent discussion and result disclosure. Our study underscores leadership support and peer connection with those in similar roles as essential elements for GCs' success in mainstream settings.

Access to clinical genetic services: An evaluation of patient referral characteristics and identifying barriers in Michigan.

The utilization of genetics in medical care has enhanced the utility of precision medicine and hence increased the need for clinical genetic services. These services have reduced the costs and expanded the availability of genetic testing, but their use is limited in certain populations. This study explores the access to clinical genetic services for Michigan patients referred to a genetics clinic on the western side of the state. Factors included the travel distance (miles), wait time for appointment (days from the referral date to the date of first appointment), population demographics, and cultural characteristics. A retrospective record review of all aged patients (n = 568) referred to a genetics clinic in 2018 demonstrated that all patients were insured (100%), of which majority were white-non-Hispanic (90.7%), more than half were < 10 years of age at referral (53.3%), and most of them kept their first appointment (93.5%). Our analysis showed that the wait time was associated with referral non-compliance, p < 0.01. Adjusting for all variables, for each additional day in wait time, patients had 1% increased risk of not seeking clinical genetic services (OR = 1.01, 90% CI [1.01, 1.02]). Policies to encourage genetic service utilization and improve equitable access to precision health are needed. An opportunity exists for strategies that broaden and add diverse populations to those receiving genetic services.

Adherence to cancer screening for patients with Li-Fraumeni syndrome: A report on our experience at Fred Hutchinson Cancer Center.

e22553 Background: Li-Fraumeni syndrome (LFS) is a high-risk cancer predisposition syndrome where patients are at risk of developing multiple primary cancers, synchronous, and metachronous cancers in their lifetimes. Patients with LFS often serve as their own advocates to request and receive appropriate cancer screening as few clinicians have experience in caring for them and few clinics are adequately staffed to provide complex cancer screening coordination. Methods: Fred Hutchinson Cancer Center (Fred Hutch) is a large academic cancer care center associated with the University of Washington. In July 2020, Fred Hutch's clinical cancer genetic service launched a high-risk surveillance clinic for patients with hereditary cancer syndromes requiring services from multiple specialties. Our clinic has since helped patients with LFS receive coordinated cancer screening. Here we report on adherence to the Toronto protocol by reviewing patient demographic, cancer history and family history, and genetic records. Furthermore, we report on the number of visits, types of screening, and cancer diagnoses patients with LFS received since enrolling in the high-risk clinic. Results: A total of 112 patients with LFS were seen in the high-risk surveillance clinic between July 2020 and December 2023. Of these patients’ paths reviewed so far, 73 patients established with the clinic and received blood work and/or MRI imaging scans, and 42 were seen in at least one follow up visit. 2 patients with LFS were diagnosed with one or more new cancer diagnosis since enrollment, both have completed treatment, and both are without evidence of disease as of February 2024. Conclusions: The high-risk surveillance clinic was promptly utilized by patients with LFS for coordination of their complex cancer screening needs and to guide their next steps when triaging symptoms and concerns. While the clinic addresses a gap in cancer screening coordination, patients with LFS need wrap around care close to where they live which is difficult to accomplish in the Pacific Northwest.

Lessons learned in migrating from one commercial genetics decision-support tool to another: Assessment of data integrity and utilization readiness.

e23232 Background: Rapid advancements in health information technology have greatly influenced how clinicians engage with patient health data. In the context of clinical genetics, the electronic health record (EHR) often contains a wide array of data to identify patients at elevated risk for hereditary cancer syndromes. However, these data often exist in multiple forms and disparate locations, which in the presence of numerous commercial EHR solutions, results in significant variations in how institutions codify genetic data. Furthermore, within an institution, there is often internal pressure to migrate from one support tool to another, necessitating a focus on data integrity during such a transition. Methods: Fred Hutchinson Cancer Center (Fred Hutch) is a large academic cancer care center associated with the University of Washington. Between July and December 2023, the Fred Hutch Clinical Cancer Genetics and Genetic Counseling Service migrated their family history database from commercial pedigree software, Progeny, to another commercial pedigree and decision-support tool, CancerIQ. Following completion of the data migration on more than 13,000 patient records, study team planned to review a total of 500 randomly selected patient charts in both support tools. Each chart was reviewed to determine: (1) the presence of genetic intake information, (2) the presence and results of genetic testing, if available, and (3) whether the patient met National Comprehensive Cancer Network (NCCN) criteria for testing. A chart was noted to be concordant between the two support tools if there was agreement in all three of the above. Results: So far, a total of 240 patient charts were reviewed between the two support tools. Of these, 226 (94.2%) were noted to be fully concordant. Of the 14 charts that were noted to be discordant, the distribution of the discordant data was: 5 charts differed on whether genetic testing had been ordered, 5 charts differed on the results of the testing (often omitting one or more variants), and 4 differed on whether the patient met NCCN criteria for testing. Conclusions: At our institution, there was high data integrity following migration from one commercial and pedigree-generating software solution to another. While these results can ease clinician concerns following such support tools transitions, it also highlights areas for improvement in how family and patient genetic data is recorded.

Reanalysis of genomic data in rare disease: current practice and attitudes among Australian clinical and laboratory genetics services.

Reanalyzing stored genomic data over time is highly effective in increasing diagnostic yield in rare disease. Automation holds the promise of delivering the benefits of reanalysis at scale. Our study aimed to understand current reanalysis practices among Australian clinical and laboratory genetics services and explore attitudes towards large-scale automated re-analysis. We collected audit data regarding testing and reanalysis volumes, policies and procedures from all Australian diagnostic laboratories providing rare disease genomic testing. A genetic health professionals' survey explored current practices, barriers to reanalysis, preferences and attitudes towards automation. Between 2018 and 2021, Australian diagnostic laboratories performed over 25,000 new genomic tests and 950 reanalyses, predominantly in response to clinician requests. Laboratory and clinical genetic health professionals (N = 134) identified workforce capacity as the principal barrier to reanalysis. No specific laboratory or clinical guidelines for genomic data reanalysis or policies were identified nationally. Perceptions of acceptability and feasibility of automating reanalysis were positive, with professionals emphasizing clinical and workflow benefits. In conclusion, there is a large and rapidly growing unmet need for reanalysis of existing genomic data. Beyond developing scalable automated reanalysis pipelines, leadership and policy are needed to successfully transform service delivery models and maximize clinical benefit.

Survey of patient satisfaction with genetic counseling services in Korea.

Since the 1990s, genetic clinics have been established in South Korea, enabling the provision of clinical genetics services. However, genetic counseling services are not widely used in the medical system. In contrast, recently, the demand for genetic counseling has increased due to the rapid development of genomic medicine. Therefore, it is important for medical geneticists and genetic counselors to collaboratively provide genetic counseling services. This study aimed to evaluate the perception and satisfaction of patients with rare genetic diseases and their families regarding genetic counseling services provided by a genetics team at the medical genetics center of a tertiary general hospital for rare genetic diseases. From April to November 2021, a survey was conducted with 203 individuals, including 111 and 92 individuals in the patient and family groups, respectively. Overall, 164 individuals (80.8%) responded that they were aware of genetic counseling services, and 135 individuals (66.5%) responded that they were aware of the role of genetic counselors. Patients and their families wanted to receive information about the following from genetic counseling: clinical manifestation and prognosis of the diagnosed disease (78.8%), treatment and management of the disease (60.6%), risk of recurrence within the family (55.7%), treatment options and alternatives for family and prenatal testing, and various support services. The score of satisfaction with genetic counseling services provided by the genetics team was 8.19 ± 1.68 out of 10. Patients with rare genetic diseases and their families were satisfied with genetic counseling services regarding their diseases, test results, and treatment options. Moreover, the patients could receive psychosocial support and referrals to other medical service providers and support services. As a genetic team approach, collaboration between medical geneticists and certified genetic counselors would be useful in providing information and in diagnosing, treating, and managing patients.

The comprehensive English National Lynch Syndrome Registry: development and description of a new genomics data resource

Lynch Syndrome (LS) is a cancer predisposition syndrome caused by constitutional pathogenic variants in the mismatch repair (MMR) genes. To date, fragmentation of clinical and genomic data has restricted understanding of national LS ascertainment and outcomes, and precluded evaluation of NICE guidance on testing and management. To address this, via collaboration between researchers, the National Disease Registration Service (NDRS), NHS Genomic Medicine Service Alliances (GMSAs), and NHS Regional Clinical Genetics Services, a comprehensive registry of LS carriers in England has been established. For comprehensive ascertainment of retrospectively identified MMR pathogenic variant (PV) carriers (diagnosed prior to January 1, 2023), information was retrieved from all clinical genetics services across England, then restructured, amalgamated, and validated via a team of trained experts in NDRS. An online submission portal was established for prospective ascertainment from January 1, 2023. The resulting data, stored in a secure database in NDRS, were used to investigate the demographic and genetic characteristics of the cohort, censored at July 25, 2023. Cancer outcomes were investigated via linkage to the National Cancer Registration Dataset (NCRD). A total of 11,722 retrospective and 570 prospective data submissions were received, resulting in a comprehensive English National Lynch Syndrome Registry (ENLSR) comprising 9030 unique individuals. The most frequently identified pathogenic MMR genes were MSH2 and MLH1 at 37.2% (n=3362) and 29.1% (n=2624), respectively. 35.9% (n=3239) of the ENLSR cohort received their LS diagnosis before their first cancer diagnosis (presumptive predictive germline test). Of these, 6.3% (n=204) developed colorectal cancer, at a median age of initial diagnosis of 51 (IQR 40-62), compared to 73 years (IQR 64-80) in the general population (p<0.0001). The ENLSR represents the first comprehensive national registry of PV carriers in England and one of the largest cohorts of MMR PV carriers worldwide. The establishment of a secure, centralised infrastructure and mechanism for routine registration of newly identified carriers ensures sustainability of the data resource. This work was funded by the Wellcome Trust, Cancer Research UK and Bowel Cancer UK. The funder of this study had no role in study design, data collection, data analysis, data interpretation, or writing of the report.

Patterns of referrals to regional clinical genetics services for women potentially at above-population level risk of breast cancer

BackgroundThe National Institute for Health and Care Excellence (NICE) recommends that women in England at above-population risk be offered additional breast screening and, depending on the level of risk, risk-reducing medication or surgery.MethodsWe reviewed the hospital records of GP referrals made to two large genetics services in England between 01/12/2021-30/11/2022 for women aged 18–49 years and suspected to be at above-population level risk for breast cancer. We compared the women referred with the wider population and estimates of the number of women at above-population level risk using published data.ResultsUp to 20% of women referred did not provide sufficient information for a complete risk assessment and over 25% were considered at near-population level risk after assessment. We estimate that only a small fraction (<10%) of those above population level risk are identified and women in areas of lower deprivation are disproportionately represented amongst referrals.ConclusionsMany women are missing out on potential preventative and risk-reducing interventions for breast cancer and current pathways may be exacerbating existing health inequalities. Better systems for collecting data on family history, improved methods for risk assessment in general practice and more systematic risk assessment of women prior to population-based screening are needed.

Prevalence and clinical characterization of oral clefts in patients with chromosome trisomy 18.

To verify the prevalence and perform the clinical characterization of oral clefts in a sample of patients with trisomy of chromosome 18 in Southern Brazil. This was a retrospective cross-sectional study, performed in a reference clinical genetic service in Southern Brazil. Theinitial sample consisted of 77 patients diagnosed in the neonatal period with trisomy 18 treated at the Clinical Genetics Service of a referral hospital at Federal University of Health Sciences of Porto Alegre (UFCSPA). The patients' diagnosis was confirmed by karyotype and care was provided during their stay in the intensive care unit (ICU) of the hospital that is a reference in Southern Brazil for care for malformed patients. The period covered was from 1975 to 2020. During the study period, 77 patients diagnosed with trisomy 18 were treated, most of them in the ICU. Of these, 13 individuals were excluded due to incomplete data. The final sample consisted of 64 patients with an average age of 2.4 years of life, ranging from one day to 16 years old, the majority of whom were female. Regarding face dysmorphisms identified in the sample, three (4,68%) patients had cleft lip and two (3,11%) had cleft lip and palate. This study contributed to the recognition of the characteristics and prevalence of oral clefts in individuals with trisomy 18 in a sample of patients from Southern Brazil. Inaddition, we described the clinical alterations found in patients with oral clefts, as well as other associated comorbidities, such as cardiac, neurological and pulmonary comorbidities, as well as cranial and facial dysmorphisms.

Genetic counselling resources in non-english languages: A scoping review.

Genetic counselling is essential for individuals seeking genetic or genomic testing. Whereas innovative strategies for GC delivery are being explored to meet the growing demand on the clinical genetics workforce, it is essential to consider the unique needs of culturally and linguistically diverse populations. We conducted a scoping review to examine the extent, range, and gaps in the body of non-English, patient-facing educational resources available for Limited English Proficient (LEP) patients accessing clinical genetics and genomics services. The literature search returned 246 unique resources, most available in several languages. Forty-six languages were represented, with Spanish, Russian, and French being the most common. Resources were in various formats and were of varying quality. There is a lack of high-quality supplementary genetics education material available in languages other than English, which limits the quality-of-care that LEP families may receive compared to their English-speaking counterparts. Of equal concern is the difficulty in finding existing resources and in determining their quality. This research highlights the important need for genetics education material that is of good quality in languages other than English and the challenges associated with identifying this material. A central, curated repository, perhaps sponsored by a genetic counselling organization, would be of great benefit to help genetic counsellors meet the needs of their culturally and linguistically diverse patients.

Medical students' self-perceived knowledge and clinical comfort with genetics in Pakistan.

Pakistan has a high rate of genetic disorders and neonatal mortality concurrent with noted lack of genetic counselors and geneticists. To meet the needs of the patient population, the responsibility of providing clinical genetic services falls on general and specialty physicians. However, their education regarding these essential services is not standardized in medical school curricula nor has it ever been evaluated. The purpose of this work is to describe the self-perceived knowledge, clinical comfort, and perspectives of Pakistani medical students toward their medical genetics' education. A web-based survey was distributed electronically to medical schools around the country. The survey comprised of four sections: (1) participant demographics, (2) self-perceived medical genetics knowledge, (3) level of comfort in applying genetic knowledge and skills, and (4) attitudes toward medical genetics education. Descriptive statistics and a one-way analysis of variance were used for data analysis. Medical students in years 3, 4, and 5 (n = 473) from 25 medical schools participated in this research representing medical education in four Pakistani provinces. Most medical students reported "minimal" to "basic" knowledge of genetic testing methodology (64.7%), cancer genetics (64.9%), prenatal genetic testing (63.02%), and treatment strategies for genetic disease (72.9%). A plurality of students (37%) reported they were uncomfortable with interpreting and communicating genetic test results to patients. Medical students also expressed dissatisfaction with their medical genetics (40%) and genetic counselors training (42%). The self-perceived knowledge and clinical comfort with genetics among Pakistani medical students was limited, especially regarding genetic testing. A significant portion (74.5%) expressed desire for additional genetics education during medical school to aid in their role as future physicians. It is important for physicians-in-training to have a solid understanding of genetic concepts, technologies, and genetic counseling to best support their patients. As endorsed by the participating medical students, this study supports inclusion of more robust genetics' education into Pakistan's medical school curricula.

Personalising genetic counselling (POETIC) trial: Protocol for a hybrid type II effectiveness-implementation randomised clinical trial of a patient screening tool to improve patient empowerment after cancer genetic counselling

BackgroundGenetic counselling aims to identify, and address, patient needs while facilitating informed decision-making about genetic testing and promoting empowerment and adaptation to genetic information. Increasing demand for cancer genetic testing and genetic counsellor workforce capacity limitations may impact the quality of genetic counselling provided. The use of a validated genetic-specific screening tool, the Genetic Psychosocial Risk Instrument (GPRI), may facilitate patient-centred genetic counselling. The aim of this study is to assess the effectiveness and implementation of using the GPRI in improving patient outcomes after genetic counselling and testing for an inherited cancer predisposition.MethodsThe PersOnalising gEneTIc Counselling (POETIC) trial is a hybrid type 2 effectiveness-implementation trial using a randomised control trial to assess the effectiveness of the GPRI in improving patient empowerment (primary outcome), while also assessing implementation from the perspective of clinicians and the healthcare service. Patients referred for a cancer risk assessment to the conjoint clinical genetics service of two metropolitan hospitals in Victoria, Australia, who meet the eligibility criteria and consent to POETIC will be randomised to the usual care or intervention group. Those in the intervention group will complete the GPRI prior to their appointment with the screening results available for the clinicians’ use during the appointment. Appointment audio recordings, clinician-reported information about the appointment, patient-reported outcome measures, and clinical data will be used to examine the effectiveness of using the GPRI. Appointment audio recordings, health economic information, and structured interviews will be used to examine the implementation of the GPRI.DiscussionThe POETIC trial takes a pragmatic approach by deploying the GPRI as an intervention in the routine clinical practice of a cancer-specific clinical genetics service that is staffed by a multidisciplinary team of genetics and oncology clinicians. Therefore, the effectiveness and implementation evidence generated from this real-world health service setting aims to optimise the relevance of the outcomes of this trial to the practice of genetic counselling while enhancing the operationalisation of the screening tool in routine practice.Trial registrationAustralian New Zealand Clinical Trials Registry registration number 12621001582842p.

Psychiatrists' perceptions of and reactions to a simulated psychiatric genetic counseling session.

Psychiatric genetic counseling (pGC) has been demonstrated to have meaningful positive outcomes for people with psychiatric conditions and their families. However, it is not widely accessed, and clinical genetics services tend to receive few referrals for these indications. Little research has evaluated psychiatrists' perceptions of and experience with interfacing with pGC. Therefore, we invited Ontario-based psychiatrists to participate in a study in which they first watched a simulated pGC session (representative of typical practice: the patient had depression with no exceptionally dense family history of psychiatric conditions, no genetic testing is provided, and no family-based risk assessment is performed), then completed zoom-based qualitative semi-structured interviews. Interviews were recorded, transcribed verbatim and checked for accuracy. Using interpretive description to analyze interviews with 12 psychiatrists (data collection was stopped at this point, as theoretical sufficiency was achieved), we generated two theoretical models: the first described the decision-making pathway psychiatrists currently follow when determining whether and how to address genetics with a patient; the second described psychiatrists' ideas for integrating pGC into care models for the future. Our data shed light on how to facilitate the delivery of pGC for people with psychiatric conditions and their families.

Experience conducting a community-engaged student research project involving an underrepresented community: A reflective essay.

Recruiting racially and ethnically underrepresented participants into genetics research studies has been challenging. While many institutions have taken steps to address the inequity in genetics research, genetic counseling training programs have the chance to inspire students to engage with underrepresented communities through utilizing different research methodologies. These methodologies can help students focus on research projects that increase access to genetics services and improve clinical care. Community-engaged research (CER) presents a pedagogical approach to enhance service-learning opportunities for students. Furthermore, it allows students to develop practical research skills for doing research with the community, rather than on the community. CER is a collaborative community-academic partnership that leads to mutual benefit and outcomes such as inclusion and engagement of the community in research, building trust and relationships, and increasing cultural awareness and exposure. In addition, CER can be used to address research and healthcare inequities by providing opportunities for genetics professionals and trainees to work closely with underrepresented populations. We aim to highlight the opportunities CER provides to students, mentors, and faculty within the context of graduate research in genetic counseling training from the experiences of a student and an educator. In addition, we hope to emphasize the necessity for projects like these to address the gaps in participation of underrepresented patient populations in research and identify areas that are mutually beneficial to improve health outcomes, patient care experiences, access, and service delivery. This reflective essay illustrates the completion of a CER project that was developed in collaboration with community members to address gaps in clinical genetics services in Indigenous healthcare.

Clinical, biochemical and molecular analysis in a cohort of individuals with gyrate atrophy

BackgroundGyrate atrophy of the choroid and retina is a rare autosomal recessive metabolic disorder caused by biallelic variants in the OAT gene, encoding the enzyme ornithine δ-aminotransferase. Impaired enzymatic activity leads to systemic hyperornithinaemia, which in turn underlies progressive chorioretinal degeneration. In this study, we describe the clinical and molecular findings in a cohort of individuals with gyrate atrophy.MethodsStudy participants were recruited through a tertiary UK clinical ophthalmic genetic service. All cases had a biochemical and molecular diagnosis of gyrate atrophy. Retrospective phenotypic and biochemical data were collected using electronic healthcare records.Results18 affected individuals from 12 families (8 male, 10 female) met the study inclusion criteria. The median age at diagnosis was 8 years (range 10 months – 33 years) and all cases had hyperornithinaemia (median: 800 micromoles/L; range: 458–1244 micromoles/L). Common features at presentation included high myopia (10/18) and nyctalopia (5/18). Ophthalmic findings were present in all study participants who were above the age of 6 years. One third of patients had co-existing macular oedema and two thirds developed pre-senile cataracts. Compliance with dietary modifications was suboptimal in most cases. A subset of participants had extraocular features including a trend towards reduced fat-free mass and developmental delay.ConclusionsOur findings highlight the importance of multidisciplinary care in families with gyrate atrophy. Secondary ophthalmic complications such as macular oedema and cataract formation are common. Management of affected individuals remains challenging due to the highly restrictive nature of the recommended diet and the limited evidence-base for current strategies.
