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.

The p.Ile490Ile variant in SLC26A4 is classified as likely benign since it is no t expected to have clinical significance because it does not alter an amino acid residue, it is not located within the splice consensus sequence, and it has bee n identified in 0.29% (101/34404) of Latino chromosomes by the Genome Aggregatio n Database (gnomAD, http://gnomad.broadinstitute.org). -
