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.

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Ser57*) in the SLC26A4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC26A4 are known to be pathogenic (PMID: 16283880, 25394566, 26252218, 26445815). This variant is present in population databases (rs111033200, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with deafness (PMID: 12676893, 25372295, 28964290). ClinVar contains an entry for this variant (Variation ID: 1075541). For these reasons, this variant has been classified as Pathogenic. -

Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. This variant has been reported as pathogenic more than twice (ClinVar: VCV001075541, PMID:12676893). It has been reported with an extremely low frequency in the gnomAD v2.1.1 (https://gnomad.broadinstitute.org/) dataset. Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Collection Method:clinical testing

The p.Ser57X variant in SLC26A4 has been reported in 1 individual with hearing loss and was compound heterozygous with a second pathogenic variant (Park 2003 PMID: 12676893), and it was absent from large population databases. This nonsense variant leads to a premature termination codon at position 57, which is predicted to lead to a truncated or absent protein. Loss of function of SLC26A4 is an established disease mechanism for autosomal recessive Pendred syndrome. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive Pendred syndrome. ACMG/AMP criteria applied: PVS1, PM3, PM2_Supporting. -
