Genes affected

SLC26A8 (HGNC:14468): (solute carrier family 26 member 8) This gene encodes a member of the SLC26 gene family of anion transporters. Family members are well conserved in gene structure and protein length yet have markedly different tissue expression patterns. The expression of this gene appears to be restricted to spermatocytes. Alternatively spliced transcript variants that encode different isoforms have been described. [provided by RefSeq, Jul 2010]

The c.2547G>T (p.K849N) alteration is located in exon 20 (coding exon 19) of the SLC26A8 gene. This alteration results from a G to T substitution at nucleotide position 2547, causing the lysine (K) at amino acid position 849 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
