Abstract
To describe the demographic distribution of cystic fibrosis (CF) in Omani children, estimate the national prevalence, and provide updated mutational panels of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. We conducted a retrospective cross-sectional study of all CF patients who had been diagnosed and followed-up at Sultan Qaboos University Hospital and Royal Hospital in Oman between 2006 and 2020. Data were collected from electronic hospital records and telephone interviews. A total of 227 patients with CF were included in the study. Geographical clusters of the disease were identified in the governorates of Al-Batinah, A'Dhahirah, and A'Dakhiliyah. Parental consanguinity and family history of CF were present in 68.3% and 69.6% of the patients, respectively. The most common CFTR mutation was p.Ser549Arg (52.0%), followed by p.Phe508del (12.3%), and c.2988+1G>A (4.4%). Three novel CFTR mutations were identified, viz., Leu88TyrFs*, p.Asp192Val, and c.4242+1G>C. The estimated prevalence of CF in Oman is 10.3 per 100 000 individuals. Premarital genetic counseling and preimplantation genetic testing are recommended in CF-prevalent regions.
