Genes affected

SLC10A7 (HGNC:23088): (solute carrier family 10 member 7) Enables bile acid transmembrane transporter activity. Involved in several processes, including cellular calcium ion homeostasis; glycoprotein transport; and heparin biosynthetic process. Located in Golgi apparatus and endoplasmic reticulum. Is intrinsic component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
• PP5: Variant 4-146305928-G-A is Pathogenic according to our data. Variant chr4-146305928-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 623254.Status of the report is no_assertion_criteria_provided, 0 stars.
