Genes affected

SLC26A4 (HGNC:8818): (solute carrier family 26 member 4) Mutations in this gene are associated with Pendred syndrome, the most common form of syndromic deafness, an autosomal-recessive disease. It is highly homologous to the SLC26A3 gene; they have similar genomic structures and this gene is located 3' of the SLC26A3 gene. The encoded protein has homology to sulfate transporters.

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 556 of the SLC26A4 protein (p.Tyr556Cys). This variant is present in population databases (rs763006761, gnomAD 0.01%). This missense change has been observed in individuals with autosomal recessive deafness and/or Pendred syndrome (PMID: 9618167, 27573290, 28281779). ClinVar contains an entry for this variant (Variation ID: 446456). 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%. Experimental studies have shown that this missense change affects SLC26A4 function (PMID: 11932316, 31599023). For these reasons, this variant has been classified as Pathogenic. -
