retinitis pigmentosa GTPase regulator interacting protein 1

From NCBI Gene:
This gene encodes a photoreceptor protein that interacts with retinitis pigmentosa GTPase regulator protein and is a key component of cone and rod photoreceptor cells. Mutations in this gene lead to autosomal recessive congenital blindness. [provided by RefSeq, Oct 2008]
May function as scaffolding protein. Required for normal location of RPGR at the connecting cilium of photoreceptor cells. Required for normal disk morphogenesis and disk organization in the outer segment of photoreceptor cells and for survival of photoreceptor cells.

- Leber congenital amaurosis 6
- Cone-rod dystrophy 13
Leber congenital amaurosis 6 (LCA6): A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. [MIM:613826]
Cone-rod dystrophy 13 (CORD13): An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. [MIM:608194]
Heterozygous non-synonymous variants of RPGRIP1 may cause or increase the susceptibility to various forms of glaucoma, a genetically heterogeneous disorder. It is the second cause of blindness worldwide owing to the progressive degeneration of retinal ganglion neurons (PubMed:21224891).
