Genes affected

SLC26A9 (HGNC:14469): (solute carrier family 26 member 9) This gene is one member of a family of sulfate/anion transporter genes. Family members are well conserved in their genomic (number and size of exons) and protein (aa length among species) structures yet have markedly different tissue expression patterns. The product of this gene is a highly selective chloride ion channel regulated by WNK kinases. Alternative splicing results in multiple transcript variants encoding differing isoforms.[provided by RefSeq, Dec 2008]

The c.1963A>G (p.S655G) alteration is located in exon 17 (coding exon 16) of the SLC26A9 gene. This alteration results from a A to G substitution at nucleotide position 1963, causing the serine (S) at amino acid position 655 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
