Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the RHO 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: Photoreceptor required for image-forming vision at low light intensity (PubMed:8107847, PubMed:7846071). Required for photoreceptor cell viability after birth (PubMed:2215617, PubMed:12566452). Light-induced isomerization of the chromophore 11-cis-retinal to all-trans-retinal triggers a conformational change that activates signaling via G-proteins (PubMed:8107847, PubMed:28524165, PubMed:26200343, PubMed:28753425). Subsequent receptor phosphorylation mediates displacement of the bound G- protein alpha subunit by the arrestin SAG and terminates signaling (PubMed:28524165, PubMed:26200343). {ECO:0000269|PubMed:12566452, ECO:0000269|PubMed:2215617, ECO:0000269|PubMed:26200343, ECO:0000269|PubMed:28753425, ECO:0000269|PubMed:7846071, ECO:0000269|PubMed:8107847, ECO:0000305|PubMed:28524165}.;
- Disease
- DISEASE: Retinitis pigmentosa 4 (RP4) [MIM:613731]: 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:12566452, ECO:0000269|PubMed:1302614, ECO:0000269|PubMed:1391967, ECO:0000269|PubMed:1833777, ECO:0000269|PubMed:1840561, ECO:0000269|PubMed:1862076, ECO:0000269|PubMed:1897520, ECO:0000269|PubMed:1985460, ECO:0000269|PubMed:19934218, ECO:0000269|PubMed:19960070, ECO:0000269|PubMed:2137202, ECO:0000269|PubMed:2215617, ECO:0000269|PubMed:22334370, ECO:0000269|PubMed:2239971, ECO:0000269|PubMed:7633434, ECO:0000269|PubMed:7981701, ECO:0000269|PubMed:7987326, ECO:0000269|PubMed:7987331, ECO:0000269|PubMed:8045708, ECO:0000269|PubMed:8076945, ECO:0000269|PubMed:8081400, ECO:0000269|PubMed:8088850, ECO:0000269|PubMed:8317502, ECO:0000269|PubMed:8353500, ECO:0000269|PubMed:8554077, ECO:0000269|PubMed:9452035}.
