Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RP1 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: Microtubule-associated protein regulating the stability and length of the microtubule-based axoneme of photoreceptors. Required for the differentiation of photoreceptor cells, it plays a role in the organization of the outer segment of rod and cone photoreceptors ensuring the correct orientation and higher-order stacking of outer segment disks along the photoreceptor axoneme (By similarity). {ECO:0000250}.
• Disease: DISEASE: Retinitis pigmentosa 1 (RP1) [MIM:180100]: 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:10391211, ECO:0000269|PubMed:10484783, ECO:0000269|PubMed:11095597, ECO:0000269|PubMed:15863674, ECO:0000269|PubMed:15933747, ECO:0000269|PubMed:19956407, ECO:0000269|PubMed:20664799, ECO:0000269|PubMed:22052604, ECO:0000269|PubMed:22334370}. Note=The disease is caused by mutations affecting the gene represented in this entry.
