Genes affected

SLC10A2 (HGNC:10906): (solute carrier family 10 member 2) This gene encodes a sodium/bile acid cotransporter. This transporter is the primary mechanism for uptake of intestinal bile acids by apical cells in the distal ileum. Bile acids are the catabolic product of cholesterol metabolism, so this protein is also critical for cholesterol homeostasis. Mutations in this gene cause primary bile acid malabsorption (PBAM); muatations in this gene may also be associated with other diseases of the liver and intestines, such as familial hypertriglyceridemia (FHTG).

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BP6: Variant 13-103066121-G-A is Benign according to our data. Variant chr13-103066121-G-A is described in ClinVar as Benign. ClinVar VariationId is 2122470.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.193 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0242 (3690/152230) while in subpopulation AFR AF = 0.0361 (1500/41546). AF 95% confidence interval is 0.0346. There are 64 homozygotes in GnomAd4. There are 1712 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 64 AR,Unknown gene
