Whole-exome sequencing reveals genetic changes in adult-onset posterior polar cataract, suggesting new avenues for diagnosis and management.

This research aims to identify genetic variations associated with adult-onset posterior polar cataract and their relevance to surgical outcomes.
Documented clinical and genetic histories of 100 PPC patients and 100 controls.
Performed whole-exome sequencing on 30 patients and 15 controls.
Validated pathogenic variants in 70 patients and 85 controls using Sanger sequencing.
Bilateral PPC was observed in 58% of patients; 61% had sporadic cases and 39% had a family history.
Phacoemulsification was performed on 89 patients, with 12 experiencing posterior capsular rupture (PCR).
Identified novel and known genetic variations across several genes, including CRYAB, CRYBG3, and GJA3, particularly in PCR cases.

Sharma et al. (2026) studied this question.
