Genes affected
SLC26A4-AS1 (HGNC:22385): (SLC26A4 antisense RNA 1)
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.

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineDec 19, 2018The c.-60A>G variant in SLC26A4 has been previously reported in 1 individual wit h unilateral enlarged vestibular aqueduct (Choi 2009), but has also been identif ied in 0.15% (13/8710) of African chromosomes by gnomAD (http://gnomad.broadinst itute.org). This variant is in the 5' untranslated region and the impact, if any , on the protein is unknown. In summary, the clinical significance of this varia nt is uncertain.

Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesSep 15, 2023The SLC26A4 c.-60A>G variant is located in the 5' untranslated region. This variant was reported in an individual with hearing loss due to an enlarged vestibular aqueduct (Choi et al 2009. PubMed ID: 19204907). This variant is reported in 0.15% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-107301244-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
