Clinical characteristics and disease progression of retinitis pigmentosa associated with PDE6B mutations in Korean patients.

ABSTRACT: Due to the genotype-phenotype heterogeneity in retinitis pigmentosa (RP), molecular diagnoses and prediction of disease progression is difficult. This study aimed to report ocular and genetic data from Korean patients with PDE6B-associated RP (PDE6B-RP), and establish genotype-phenotype correlations to predict the clinical course. We retrospectively reviewed targeted next-generation sequencing or whole exome sequencing data for 305 patients with RP, and identified PDE6B-RP in 15 patients (median age, 40.0 years). Amongst these patients, ten previously reported PDE6B variants (c.1280G > A, c.1488del, c.1547T > C, c.1604T > A, c.1669C > T, c.1712C > T, c.2395C > T, c.2492C > T, c.592G > A, and c.815G > A) and one novel variant (c.712del) were identified. Thirteen patients (86.7%) experienced
