RPGR Gene (Protein Coding)

Retinitis Pigmentosa GTPase Regulator

GC0XM038269
GIFtS:
41
This gene encodes a protein with a series of six RCC1-like domains (RLDs), characteristic of the highly conserved guanine nucleotide exchange factors. The encoded protein is found in the Golgi body and interacts with RPGRIP1. This protein localizes to the outer segment of rod photoreceptors and is essential for their viability. Mutations in this gene have been associated with X... See more...

Summaries for RPGR Gene

Entrez Gene Summary for RPGR Gene

  • This gene encodes a protein with a series of six RCC1-like domains (RLDs), characteristic of the highly conserved guanine nucleotide exchange factors. The encoded protein is found in the Golgi body and interacts with RPGRIP1. This protein localizes to the outer segment of rod photoreceptors and is essential for their viability. Mutations in this gene have been associated with X-linked retinitis pigmentosa (XLRP). Multiple alternatively spliced transcript variants that encode different isoforms of this gene have been reported, but the full-length natures of only some have been determined.

GeneCards Summary for RPGR Gene

RPGR (Retinitis Pigmentosa GTPase Regulator) is a Protein Coding gene. Diseases associated with RPGR include Retinitis Pigmentosa, X-Linked, And Sinorespiratory Infections, With Or Without Deafness and Retinitis Pigmentosa 3. Gene Ontology (GO) annotations related to this gene include guanyl-nucleotide exchange factor activity. An important paralog of this gene is HERC1.

UniProtKB/Swiss-Prot Summary for RPGR Gene

  • Could be a guanine-nucleotide releasing factor. Plays a role in ciliogenesis. Probably regulates cilia formation by regulating actin stress filaments and cell contractility. Plays an important role in photoreceptor integrity. May play a critical role in spermatogenesis and in intraflagellar transport processes (By similarity). May be involved in microtubule organization and regulation of transport in primary cilia.

RPGR_HUMAN
  • Retinitis pigmentosa 3 (RP3) [MIM:300029]: A X-linked 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. In RP3, affected males have a severe phenotype, and carrier females show a wide spectrum of clinical features ranging from completely asymptomatic to severe retinitis pigmentosa. Heterozygous women can manifest a form of choroidoretinal degeneration which is distinguished from other types by the absence of visual defects in the presence of a brilliant, scintillating, golden-hued, patchy appearance most striking around the macula, called a tapetal-like retinal reflex. {ECO:0000269 PubMed:10482958, ECO:0000269 PubMed:10737996, ECO:0000269 PubMed:10932196, ECO:0000269 PubMed:10937588, ECO:0000269 PubMed:10970770, ECO:0000269 PubMed:11180598, ECO:0000269 PubMed:11992260, ECO:0000269 PubMed:12657579, ECO:0000269 PubMed:14564670, ECO:0000269 PubMed:24981858, ECO:0000269 PubMed:8673101, ECO:0000269 PubMed:8817343, ECO:0000269 PubMed:9399904, ECO:0000269 PubMed:9855162}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Retinitis pigmentosa and sinorespiratory infections with or without deafness (RPDSI) [MIM:300455]: A disease characterized by the association primary ciliary dyskinesia features with retinitis pigmentosa. Some patients also manifest deafness. {ECO:0000269 PubMed:12920075, ECO:0000269 PubMed:14627685}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Cone-rod dystrophy, X-linked 1 (CORDX1) [MIM:304020]: 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. In cone-rod dystrophy X-linked type 1 the degree of rod-photoreceptor involvement can be variable, with degeneration increasing as the disease progresses. Affected individuals (essentially all of whom are males) present with decreased visual acuity, myopia, photophobia, abnormal color vision, full peripheral visual fields, decreased photopic electroretinographic responses, and granularity of the macular retinal pigment epithelium. Although penetrance appears to be nearly 100%, there is variable expressivity with respect to age at onset and severity of symptoms. {ECO:0000269 PubMed:11857109}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Macular degeneration, X-linked, atrophic (MDXLA) [MIM:300834]: An ocular disorder characterized by macular atrophy causing progressive loss of visual acuity with minimal peripheral visual impairment. Some patients manifest extensive macular degeneration plus peripheral loss of retinal pigment epithelium and choriocapillaries. Full-field electroretinograms (ERGs) show normal cone and rod responses in some affected males despite advanced macular degeneration. {ECO:0000269 PubMed:12160730}. Note=The disease is caused by mutations affecting the gene represented in this entry.
