Peripherin 2 (Prph2) is a photoreceptor tetraspanin, and deletion of codon 153 (K153Δ) leads to retinitis pigmentosa, pattern dystrophy, and fundus flavimaculatus in the same family.
Mutations in the ATP-binding cassette, subfamily A, member 4 (ABCA4), elongation of very long chain fatty acids 4 (ELOVL4) and peripherin-2 (PRPH2) genes have been identified in patients with Stargardt macular degeneration (STGD).
A novel p.Trp94X mutation in RDS was found in all three affected members of a two-generation family that was associated with retinitis pigmentosa in the son, pattern dystrophy in the daughter and fundus flavimaculatus in the mother.
