LCA18

PRPH2

Peripherin 2 (RDS); structural glycoprotein of photoreceptor outer segment disc rims. Heterozygous mutations cause RP7 and various macular dystrophies (AD); homozygous mutations cause LCA18 (AR) with earlier onset retinal dystrophy.

Aktif Klinik Çalışmalar

A personalized antisense-oligonucleotide (ASO) therapy for a single participant with a specific pathogenic PRPH2 variant is in a Phase 1/2 study run by the n-Lorem Foundation (nL-PRPH2-001; NCT07177196) — an individualized (n-of-1) treatment, not a generalizable program. Peripherin-2 gene-augmentation proof-of-concept dates back decades to the rds mouse, where AAV delivery restored photoreceptor ultrastructure and function (Ali et al., Nature Genetics 2000).
