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.

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 16, 2024	This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 514 of the SLC26A4 protein (p.Gln514Arg). This variant is present in population databases (rs111033316, gnomAD 0.01%). This missense change has been observed in individuals with Pendred syndrome (PMID: 15689455, 25394566, 26969326). ClinVar contains an entry for this variant (Variation ID: 43511). 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: 19204907). This variant disrupts the p.Gln514 amino acid residue in SLC26A4. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 18285825, 19017801). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Feb 01, 2021	Published functional studies demonstrate a damaging effect; L90P interferes with proper localization of the SLC26A4 protein (Choi et al., 2009); 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: 26969326, 15689455, 19204907, 25394566, 19318451, 23555729) -
