Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the STRC gene is commonly pathogenic or not. These statistics are base on transcript: . 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: Essential to the formation of horizontal top connectors between outer hair cell stereocilia. {ECO:0000250}.;
Disease: DISEASE: Deafness, autosomal recessive, 16 (DFNB16) [MIM:603720]: A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. {ECO:0000269|PubMed:11687802}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Deafness-infertility syndrome (DIS) [MIM:611102]: Characterized by deafness and infertility and is caused by large contiguous gene deletions at 15q15.3 that removes both STRC and CATSPER2 genes. {ECO:0000269|PubMed:17098888}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
