Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RS1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000000330.4. Only rare variants are included in the table.

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: Binds negatively charged membrane lipids, such as phosphatidylserine and phosphoinositides (By similarity). May play a role in cell-cell adhesion processes in the retina, via homomeric interaction between octamers present on the surface of two neighboring cells (PubMed:27114531). Required for normal structure and function of the retina (PubMed:19093009). {ECO:0000250|UniProtKB:Q9Z1L4, ECO:0000269|PubMed:19093009, ECO:0000305|PubMed:27114531}.;
Disease: DISEASE: Retinoschisis juvenile X-linked 1 (XLRS1) [MIM:312700]: A vitreo-retinal dystrophy characterized by macular pathology and by splitting of the superficial layer of the retina. Macular changes are present in almost all cases. In the fundi, radially oriented intraretinal foveomacular cysts are seen in a spoke-wheel configuration, with the absence of foveal reflex in most cases. In addition, approximately half of cases have bilateral peripheral retinoschisis in the inferotemporal part of the retina. Aside from the typical fundus appearance, strabismus, nystagmus, axial hyperopia, defective color vision and foveal ectopy can be present. The most important complications are vitreous hemorrhage, retinal detachment, and neovascular glaucoma. {ECO:0000269|PubMed:10079181, ECO:0000269|PubMed:10220153, ECO:0000269|PubMed:10234514, ECO:0000269|PubMed:10450864, ECO:0000269|PubMed:10533068, ECO:0000269|PubMed:17304551, ECO:0000269|PubMed:17615541, ECO:0000269|PubMed:17631851, ECO:0000269|PubMed:19093009, ECO:0000269|PubMed:19849666, ECO:0000269|PubMed:27798099, ECO:0000269|PubMed:9326935, ECO:0000269|PubMed:9760195, ECO:0000269|Ref.14}.
