Summaries for RS1 Gene

Entrez Gene Summary for RS1 Gene

  • This gene encodes an extracellular protein that plays a crucial role in the cellular organization of the retina. The encoded protein is assembled and secreted from photoreceptors and bipolar cells as a homo-oligomeric protein complex. Mutations in this gene are responsible for X-linked retinoschisis, a common, early-onset macular degeneration in males that results in a splitting of the inner layers of the retina and severe loss in vision. [provided by RefSeq, Oct 2008]

  • Retinoschisis juvenile X-linked 1 (XLRS1) [MIM:312700]: A vitreo-retinal dystrophy characterized by macular pathology and by splitting of the superficial layer of the retina. Macular changes are present in almost all cases. In the fundi, radially oriented intraretinal foveomacular cysts are seen in a spoke-wheel configuration, with the absence of foveal reflex in most cases. In addition, approximately half of cases have bilateral peripheral retinoschisis in the inferotemporal part of the retina. Aside from the typical fundus appearance, strabismus, nystagmus, axial hyperopia, defective color vision and foveal ectopy can be present. The most important complications are vitreous hemorrhage, retinal detachment, and neovascular glaucoma. {ECO:0000269 PubMed:10079181, ECO:0000269 PubMed:10220153, ECO:0000269 PubMed:10234514, ECO:0000269 PubMed:10450864, ECO:0000269 PubMed:10533068, ECO:0000269 PubMed:17304551, ECO:0000269 PubMed:17615541, ECO:0000269 PubMed:19093009, ECO:0000269 PubMed:9326935, ECO:0000269 PubMed:9760195, ECO:0000269 Ref.10}.
