Update on Genetic Counselor Practice and Recommendations for Pediatric Cancer Predisposition Evaluation and Surveillance.

In July 2023, the American Association for Cancer Research held the second Childhood Cancer Predisposition Workshop, at which international experts in pediatric cancer predisposition met to update the previously published 2017 consensus statements on pediatric cancer predisposition syndromes. Since 2017, advances in tumor and germline genetic testing and increased understanding of cancer predisposition in patients with pediatric cancer have led to significant changes in clinical care. Here, we provide an updated genetic counseling framework for pediatric oncology professionals. The framework includes referral indications and timing, somatic and germline genetic testing options, testing for adult-onset cancer predisposition syndromes in children with and without cancer, evolving genetic counseling models to meet the increased demand for genetic testing, barriers to cancer genetic testing and surveillance in children, and psychosocial and equity considerations regarding cancer genetic testing and surveillance in children. Adaptable genetic counseling services are needed to provide support to pediatric oncology provider teams and diverse patients with pediatric cancer, cancer predisposition, and their families.

Landscape of genetic counseling in the Philippines.

In this paper, we report on the professional development of genetic counselors in the Philippines as we discuss the status of genetic counseling training and research, along with the roles and scope of practice of genetic counselors. The development of a master's level training program for non-physician genetic counselors in the Philippines initiated in 2011 was in response to the increasing demand for genetic counseling services. There are currently 18 locally trained genetic counselors who are practicing in various fields including newborn screening, pediatrics, cancer, prenatal and preconception, neurology, and research. Despite the success of the genetic counseling training program, various professional challenges hinder maximizing the impact of genetic counselors in the health system. The challenges discussed in this paper include the limited number of genetic counselors, the lack of government positions officially recognizing the 'genetic counselor' title, and the absence of a regulatory framework. These issues require thorough discussion with appropriate government agencies and collaboration with other healthcare professional organizations with the ultimate goal of ensuring quality genetic counseling services nationwide.

Integrating genetic assistants into the workforce: An 18-year productivity analysis and development of a staff mix planning tool.

In recent years, genetic (counseling) assistants have been integrated in the genetics workforce, such that one-third of genetic counselors now report working with a genetic assistant. While several studies showed that adoption of the genetic assistant model leads to an increase in patient volume, the impact of this role substitution has not been studied quantitatively beyond the cancer genetics workforce. This study utilized 18years of data from a publicly funded genetics clinic with multiple specialties and varying staff mix. Time series regression modeling was applied to describe the evolving impact of genetic assistants on genetic counselor and clinical geneticist productivity (measured as patient volume). The regression models suggest that the integration of genetic assistants led to a sustainable increase in genetic counselor patient volume, while clinical geneticist patient volume was unaffected. Importantly, the models also demonstrated an interaction between the number of genetic counselors and genetic assistants, whereby the impact of adding a genetic counselor was greater as more genetic assistants were employed in the clinic, and vice versa. The main regression model was used to create "ClinMix: A Genetics Staff Mix Planning Tool," an Excel application that allows users to explore how different staffing plans could affect patient volume, by applying the parameters estimated from this data or their own. We hope this report and the ClinMix tool can be employed by the genetics workforce to advocate for further implementation and evaluation of genetic assistant positions. Adoption of the genetic assistant model may provide clinics the support needed to meet increasing service delivery demands and subsequently foster genetic counselor practice at "top of scope."

Examining the role of language competency in genetic testing awareness among adults in the United States.

English language competency, as a component of health literacy, is associated with increased awareness and uptake of health-related genetic testing. The relationship between language competency and genetic testing awareness has not yet been explored in the wider U.S. population yet has significant implications for the practice of genetic counselors and in the promotion of genomic medicine for public health. We analyzed data from the 2017 Health Information National Trends Survey 5 Cycle 1 using weighted logistic regression to model the relationship between self-reported English competency, genetic testing awareness, and race and explore adjusted odds ratios and average marginal effects for levels of English competency. Compared to respondents with high English competency, the probability of genetic testing awareness was 20 percentage points lower for White participants reporting moderate English competency (p=.029) and 37 percentage points lower for non-White participants reporting low English competency (p<.001). Future research is needed to understand the mechanisms through which English competency affects awareness and uptake of genetic testing in the United States and to develop strategies to overcome language barriers for the practice of genetic counselors and the implementation of genetics services.

Rapid acute care genomics: Challenges and opportunities for genetic counselors.

Genomic medicine in pediatric acute care is showing great promise, with rapid results from exome and genome sequencing returned within days providing critically important information for treatment and management of seriously ill children. Many have suggested that rapid acute care genomics presents novel genetic counseling issues. This is due to the need for rapid response to referrals, the immense emotional distress that parents are likely to experience when their child is in acute care, and the unfamiliar environment of the acute care setting. To explore the practice of genetic counselors in this setting, we conducted qualitative interviews with 16 genetic counselors (GCs), representing a large proportion of GCs at the frontline of providing genetic counseling in acute care settings in Australia. Interviews revealed themes describing genetic counseling in acute care, including practical challenges of counseling within a rapid turnaround time, similarities with other contexts such as prenatal counseling, and the need for education of other health professionals. Interestingly, GCs did not raise concerns in the interviews for parents' ability to provide informed consent for rapid genomic sequencing. GCs also encountered practical and organizational challenges with counseling in this setting where 24-hr care is provided, at odds with traditional '9 to 5' Genetics service delivery. Working closely in a multidisciplinary team was common and participants believed that GCs are well positioned to take a leading role in the education of other health professionals as rapid acute care genomics becomes routine clinical practice. Despite views that genetic counseling practice in rapid acute care genomics is unique, these exploratory data suggest that GCs are flexible, adaptable, and sufficiently skilled to deliver patient-centered counseling in this setting. Our work indicates GCs are ready and willing to contribute at an early stage of adoption of genomic investigations in acute care.

The de-coders: A historical perspective of the genetic counseling profession.

The genetic counseling profession is a relatively new medical specialty that has evolved over time in keeping with advanced in the medical genetics field. Genetic counselors are master's-level trained individuals who apply their skills to assist patients in understanding the genetic etiology of disease, assessing risk for genetic disease, and providing support to those who are encountering a genetic disorder in themselves or family member. Formal training of genetic counselors began nearly 50 years, and since then, the field has been expanding and advancing. Defining the tenets and practice of the genetic counseling profession has also similarly changed over time; however, the core guiding principles of the profession have remained rooted in the concept of patient autonomy and client-centered care. Competency in the field is achieved by successfully graduating from an accredited master's-level training program in which the curriculum is based on standards set forth by the Accreditation Council of Genetic Counseling. Curricula are developed so that trainees are exposed to didactic work, hands-on clinical fieldwork, and research so that at the end of one's training they have become competent in The Practice Based Competencies that have been established for the profession. Upon graduation, genetic counselors find themselves working in a number of professional settings and subspecialties in genetics. As the underlying genetic cause of disease has become clearer, the areas in which genetic counselors practice have expanded and allows for diverse clinical practice. The profession has, and will, continue to adapt along with the advances in molecular genetics.

Birds of a Feather? Genetic Counseling, Genetic Testing, and Humanism

Humanism is a philosophy that emphasizes rational, scientific, and empiric analysis of the world we live in to improve the physical, social, and psychological life of humanity. Although individual genetic counselors may or may not identify as humanists, genetic counseling and genetic testing are primarily humanistic endeavors because they are situated in the context of humanistic medicine in the westernized world. Humanistic goals are also implicit and explicit in the profession and practice of genetic counselors. This review examines the relationship between humanism and genetic counseling, highlighting situations in which the two may be discordant, and suggests ways that genetic counselors can reconcile these discordances.

Managing Couple Conflict During Prenatal Counseling Sessions: An Investigation of Genetic Counselor Experiences and Perceptions.

Research shows couple conflict occurring during prenatal genetic counseling sessions may be challenging for some genetic counselors. Yet, no study has explored couple conflict in depth. The current study investigated genetic counselors' experiences and perceptions of the nature and context of couple conflict in prenatal sessions and counselor conflict management strategies. Sixteen prenatal genetic counselors recruited through the National Society of Genetic Counselors participated in semi-structured phone interviews asking about how they recognize couple conflict; topics that trigger conflict and when it occurs; individual, cultural, and situational factors associated with conflict; conflict management strategies; and specific examples from their practice. Inductive and cross-case comparison methods revealed a number of themes. Genetic counselors recognize couple conflict through non-verbal and verbal cues, and conflict can occur at any time, particularly during decision-making about testing and test results and during results review of an affected pregnancy. Factors associated with conflict include cultural customs, age, emotional state, religious beliefs, and being forced to attend counseling. Participants identified 23 conflict management strategies classified into five themes: facilitate decision-making, encourage couple expression, act within one's scope of practice, provide psychosocial support, and support the identified patient. Counselors emphasized that their strategies are couple dependent. Patients may benefit from genetic counselors assessing couple conflict and intervening when it impedes genetic counseling goals. Clinical examples from this study may contribute to informing genetic counselor practice, program curricula, and continuing education workshops.

Sex Education and Intellectual Disability: Practices and Insight from Pediatric Genetic Counselors.

Intellectual disability (ID) with or without other anomalies is a common referral for genetic counseling. Sessions may include discussions of reproductive implications and other issues related to sex education. Patients with ID regularly meet barriers when trying to obtain sex education due to the misperceptions of others as being either asexual or that such education would promote inappropriate sexual behavior. In this pilot study, we surveyed genetic counselors to explore their experiences with being asked to provide sex education counseling and their comfort in doing so for patients with ID ages 9-17. Results were analyzed from 38 respondents. Caregivers and patients most frequently requested information on puberty, sex abuse prevention, and reproductive health. Genetic counselors were most comfortable when they could provide sex education counseling within the context of a particular condition or constellation of features. They were least comfortable when they lacked familiarity with the patient, caregiver, or the family's culture. The most frequently cited barriers that prevented genetic counselors from providing sex education counseling were lack of time, lack of training, the patient's ID being too profound, and a belief that genetic counselors should not be responsible for providing sex education counseling. While many respondents reported that providing sex education counseling is not considered within the scope of a genetic counselor's practice, they also noted that patients' families initiate discussions for which counselors should be prepared. Respondents indicated that resource guides specifically designed for use by genetic counselors would be beneficial to their practice. Genetic counselors have the opportunity to embrace the role of advocate and broach the issue of sexual health with caregivers and patients by directing them toward educational resources, if not providing sex education directly to effectively serve the needs of patients and caregivers.

Genetic Counseling in Oncology

To the Editor: Dr Tung’s review of the difficult decisions faced by women with a BRCA mutation mentioned the importance of genetic counseling in the process of clinical decision making. Decisions about definitive breast surgery, prophylactic oophorectomy, and fertility options such as preimplantation diagnosis increasingly are being informed by the awareness of a BRCA mutation. Tung commented on the importance of compensating hospitals and physicians for trained genetic counselors. Fragmented reimbursement of genetic services has limited integration of genetic counselors into a collaborative oncology care model. However, we propose reframing the question from compensation of hospitals and physicians to determining how genetic counselors—many of whom are licensed to practice independently—could be reimbursed in a manner that is in the best interests of patients, clinicians, and health care systems. Currently Medicare does not recognize genetic counselors as “providers.” Recognition would lead to increased coverage by payers and benefit patients by improving access to genetic counseling. Institutions in which genetic counselors practice with physicians would benefit by increasing their efficiency in delivering genetic services. Genetic counselor certification ensures they are proficient in selecting appropriate genetic tests and interpreting them correctly. Appropriate use of genetic testing can reduce health system costs, contrary to a recent study in which a majority of nongeneticist physicians would order unnecessary or incorrect BRCA testing at considerable additional cost. Finally, Tung states that “most genetic counseling programs cost more than they generate in revenue.” This may reflect an incomplete accounting. Any truly useful calculation of the institutional value of genetic counseling programs must include a careful study of the “downstream revenue” institutions receive from performing surveillance, prophylactic surgery, or cancer treatment for individuals with BRCA mutations.

Attitudes and Practice of Genetic Counselors Regarding Anonymous Testing for BRCA1/2

Patients and clinicians alike view anonymous testing as a potential way to avoid perceived risks of genetic testing such as insurance and employment discrimination and the potential loss of privacy. To assess their experience with and attitudes towards anonymous testing for BRCA1/2, genetic counselors were invited to complete an internet-based survey via the NSGC Familial Cancer Risk Counseling Special Interest Group (FCRC-SIG) listerv. A majority of the 115 respondents (70%) had received requests from patients for anonymous BRCA1/2 testing at some point in their careers and 43% complied with this request. Most counselors, however, encountered such requests infrequently, 1-5 times per year. Although genetic counselors do not generally encourage anonymous testing and over a third of respondents feel it should never be offered, a substantial subset support its use under specific circumstances. In general, a strong consensus exists among counselors that anonymous testing should not be offered routinely. In light of the current legislative landscape, it is of note that a substantial proportion of respondents (42.7%) cited the threat of life insurance discrimination as a reason for pursuing AT, and fewer cited health insurance (30.0%) or employment discrimination (29.1%) as justifications. Since there exists no federal legislative protections against discrimination by life insurance companies, it makes sense that genetic counselors were more responsive to this issue as opposed to the threat of discrimination in health insurance and employment.

“Testing Times, Challenging Choices”: An Australian Study of Prenatal Genetic Counseling

In many countries pregnant women deemed to be at increased risk for fetal anomaly following a screening test may attend a genetic counseling session to receive information and support in decision-making about subsequent diagnostic testing. This paper presents findings from an Australian study that explored 21 prenatal genetic counseling sessions conducted by five different genetic counselors. All were attended by pregnant women who had received an increased risk result from a maternal serum screening (MSS) test and who were offered a diagnostic test. Qualitative methods were used to analyze the content and structure of sessions and explore the counseling interactions. Findings from this cohort demonstrate that, within these prenatal genetic counseling sessions, counselor dialogue predominated. Overall the sessions were characterized by: a) an emphasis on information-giving b) a lack of dialogue about relevant sensitive topics such as disability and abortion. Arguably, this resulted in missed opportunities for client deliberation and informed decision-making. These findings have implications for the training and practice of genetic counselors and all healthcare professionals who communicate with women about prenatal testing.

A Genetic Services Practice Model: Advanced Practice Nurse and Genetic Counselor Team

Genomics or the interaction of one's genes and the environment is changing our concept of health and disease, available therapies, use of genetic testing, and related societal ramifications. As genomics integrates into all aspects of health care, the demand will increase for meaningful interpretation and application of the new genetic information. To meet this demand, new service delivery models must be considered. Nurse practitioners and genetic counselors are midlevel providers that can, together, provide clinical evaluation, case management, follow-up, and the genetic counseling aspects of a comprehensive medical genetics consultation. Midlevel providers working with a medical geneticist can expand access to this level of expertise, thereby reaching more patients and consumers. This nurse practitioner–genetic counselor practice model is described in the context of a rural setting.

Genetic Counseling for Sex Chromosome Anomalies (SCAs) in Israel and Germany: Assessing Medical Risks According to the Importance of Fertility in Two Cultures

In this article, I report findings from a comparative study of Israeli and German genetic counselors. Specifically, it concerns counselors' attitudes and risk assessments relating to prenatal diagnosis of sex chromosome anomalies (SCAs) such as Klinefelter and Turner syndromes. Data collected through in-depth interviews with counselors in both countries (N = 32) are presented, and the types of claims experts deploy in their personal and professional estimation of the risks involved in SCAs are analyzed. The article concludes by suggesting that the counselors rhetoric concerning SCAs, whose major manifestation is the future infertility of the unborn child as well as their estimations of the related risks, should be situated in a broader cultural context, that of local Israeli and German understandings of the importance of fertility, and not in their professional nondirective ethos. Hence, to understand the practice of genetic counselors in two late-modern societies, one must understand the unique relationship between the individual bodies of pregnant women and the body politics of their nations, a relationship mediated by the counselors, who are the bearers of knowledge and expertise in this field.

Commentary onBecoming a Daughter: Trauma is a Powerful Teacher

Personal life crises profoundly impact genetic counselor practice. In this commentary, themes from Matloff's (in press) article, Becoming a Daughter are highlighted and expanded upon. These themes include: personal impact of a life crisis, and professional impact vis a vis empathy countertransference, self-disclosure, nondirectiveness, and self-confidence. Strategies that help genetic counselors manage personal life crises within their clinical practice and also promote their professional development are emphasized, including normalization of life crises, self-reflection, boundary-setting, and use of peer supervision and consultation.

Does Receiving Genetic Counseling Impact Genetic Counselor Practice?

This study was an investigation of whether genetic counselors have received genetic counseling and if so, how they believe it affects their practice. One thousand genetic counselors were mailed surveys about the nature of genetic counseling services received, impact on their clinical practice, frequency and reasons for disclosing about their receipt of counseling to their clients, and demographics. Ninety-three of the 510 respondents reported receiving genetic counseling. Of these, almost three-fourths were practicing genetic counselors while receiving services. Reasons for services include prenatal concerns, family history of cancer, and history/risk of other genetic conditions. Frequently endorsed effects on practice include increased empathy and understanding of client decisions, feeling more connected with clients, greater emphasis on psychosocial support, and sympathy. Forty-six respondents disclosed to clients about their receipt of genetic counseling. Prevalent reasons include client asked, help clients feel they are not alone, demonstrate counselor understanding, decrease client anxiety, build rapport, and normalize client feelings. Practice and research recommendations are given.
