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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.41173273).

BS2

High AC in GnomAdExome4 at 32 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.2446C>T (p.R816W) alteration is located in exon 19 (coding exon 18) of the SLC26A8 gene. This alteration results from a C to T substitution at nucleotide position 2446, causing the arginine (R) at amino acid position 816 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
