Description

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 360 of the SLC26A4 protein (p.Ala360Val). This variant is present in population databases (rs786204474, gnomAD 0.06%). This missense change has been observed in individual(s) with hearing loss (PMID: 17697873, 21961810, 23838540, 26252218, 26969326). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 188793). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SLC26A4 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.

Description

Published functional studies demonstrate this variant impairs SLC26A4 protein localization and function (Yuan et al., 2012); Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 30842343, 23185506, 26969326, 23838540, 21154317, 17697873, 21961810, 26252218, 27771369, 30275481, 31541171, 24612839, 24341454, 23151025, 33199029, 32447495, 36362242, 35982127, 34416374, 33907123, 32658404)
