Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the RPGR gene is commonly pathogenic or not.
In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.
Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

- Function
- FUNCTION: 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. {ECO:0000250, ECO:0000269|PubMed:21933838}.;
- Disease
- DISEASE: 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.; DISEASE: 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.; DISEASE: 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.; DISEASE: 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.;
