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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2023The c.1658A>G (p.N553S) alteration is located in exon 15 (coding exon 15) of the SLC26A6 gene. This alteration results from a A to G substitution at nucleotide position 1658, causing the asparagine (N) at amino acid position 553 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
