Genes affected

SLC26A6 (HGNC:14472): (solute carrier family 26 member 6) This gene belongs to the solute carrier 26 family, whose members encode anion transporter proteins. This particular family member encodes a protein involved in transporting chloride, oxalate, sulfate and bicarbonate. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Aug 2013]

The c.1964G>A (p.G655E) alteration is located in exon 18 (coding exon 18) of the SLC26A6 gene. This alteration results from a G to A substitution at nucleotide position 1964, causing the glycine (G) at amino acid position 655 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
