Randomized trial reveals genetic mutations in retinitis pigmentosa families, indicating potential for prenatal diagnosis.

This study aims to explore genetic mutations and their correlation with clinical characteristics in families with retinitis pigmentosa.
Whole-exome and Sanger sequencing of genomic DNA obtained from patients' blood samples.
Performed visual acuity assessments and fundus examinations including photography.
Analyzed three RP families from the Chinese Han population.
Identified three novel variants: CERKL c.1482delT, RPRH2 c.-5_3dup, and RPGR c.1539del.
Variants cosegregated in families: PRPH2 (autosomal dominant), CERKL (autosomal recessive), RPGR (X-chromosome linked).
Foundational study for prenatal diagnosis of retinitis pigmentosa and addressing genetic heterogeneity.

Liu et al. (2025) studied this question.
