Genes affected

SLC4A2 (HGNC:11028): (solute carrier family 4 member 2) This gene encodes a member of the anion exchanger family of membrane transport proteins. The encoded protein regulates intracellular pH, biliary bicarbonate secretion, and chloride uptake. Reduced expression of this gene may be associated with primary biliary cirrhosis (PBC) in human patients, while differential expression of this gene may be associated with malignant hepatocellular carcinoma, colon and gastric cancers.

Ambry Genetics

Apr 19, 2023

The c.34G>A (p.A12T) alteration is located in exon 2 (coding exon 1) of the SLC4A2 gene. This alteration results from a G to A substitution at nucleotide position 34, causing the alanine (A) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
