Description

The OTOA c.828delT variant is predicted to result in a frameshift and premature protein termination (p.Ser277Valfs*3). This variant has been reported as pathogenic in patients with non-syndromic hearing loss (described as c.590delT, Table S2, Shearer et al. 2014. PubMed ID: 24963352; described as c.591delT, Table S3, Sloan-Heggen et al. 2016. PubMed ID: 26969326). This variant is reported in 0.015% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-21709182-AT-A). Frameshift variants in OTOA are expected to be pathogenic. This variant is interpreted as pathogenic.
