Entrez Gene Summary for PRPH2 Gene

  • The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein found in the outer segment of both rod and cone photoreceptor cells. It may function as an adhesion molecule involved in stabilization and compaction of outer segment disks or in the maintenance of the curvature of the rim. This protein is essential for disk morphogenesis. Defects in this gene are associated with both central and peripheral retinal degenerations. Some of the various phenotypically different disorders are autosomal dominant retinitis pigmentosa, progressive macular degeneration, macular dystrophy and retinitis pigmentosa digenic.

Disorders for PRPH2 Gene

(5) OMIM Diseases for PRPH2 Gene (179605)


  • Retinitis pigmentosa 7 (RP7) [MIM:608133]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:10627133, ECO:0000269 PubMed:1427912, ECO:0000269 PubMed:1684223, ECO:0000269 PubMed:1749427, ECO:0000269 PubMed:22334370, ECO:0000269 PubMed:7862413, ECO:0000269 PubMed:8020945}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Retinitis punctata albescens (RPA) [MIM:136880]: Rare form of stationary night blindness characterized by a delay in the regeneration of cone and rod photopigments. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Macular dystrophy, vitelliform, 3 (VMD3) [MIM:608161]: A form of vitelliform macular dystrophy, a retinal disease characterized by yellow, lipofuscin-containing deposits, usually localized at the center of the macula. Patients usually become symptomatic in the fourth or fifth decade of life with a protracted disease of decreased visual acuity. {ECO:0000269 PubMed:17653047, ECO:0000269 PubMed:9338584}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Macular dystrophy, patterned, 1 (MDPT1) [MIM:169150]: A form of retinal patterned dystrophy, a heterogeneous group of macular disorders that includes reticular (fishnet-like) dystrophy, macroreticular (spider-shaped) dystrophy and butterfly-shaped pigment dystrophy. {ECO:0000269 PubMed:16024869, ECO:0000269 PubMed:8485574, ECO:0000269 PubMed:9443872}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Choroidal dystrophy, central areolar 2 (CACD2) [MIM:613105]: A disease of the macula leading to a well-demarcated circumscribed area of atrophy of the pigment epithelium and choriocapillaris. {ECO:0000269 PubMed:16832026}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Defects in PRPH2 are found in different retinal diseases including cone-rod dystrophy, retinitis pigmentosa, macular degeneration. The mutations underlying autosomal dominant retinitis pigmentosa and severe macular degeneration are largely missense or small in-frame deletions in a large intradiscal loop between the third and fourth transmembrane domains. In contrast, those associated with the milder pattern phenotypes or with digenic RP are scattered more evenly through the gene and are often nonsense mutations. This observation correlates with the hypothesis that the large loop is an important site of interaction between PRPH2 molecules and other protein components in the disk.
