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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.82).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0186 (2826/152334) while in subpopulation NFE AF = 0.0267 (1813/68026). AF 95% confidence interval is 0.0256. There are 50 homozygotes in GnomAd4. There are 1387 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 50 AR gene
