Variant rs34719006 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PP2PP3

The NM_001374385.1(ATP8B1):c.208G>T(p.Asp70Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000806 in 1,613,764 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D70N) has been classified as Likely benign.

Genes affected

ATP8B1 (HGNC:3706): (ATPase phospholipid transporting 8B1) This gene encodes a member of the P-type cation transport ATPase family, which belongs to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. Mutations in this gene may result in progressive familial intrahepatic cholestasis type 1 and in benign recurrent intrahepatic cholestasis. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PP2

Missense variant in the ATP8B1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 21 curated pathogenic missense variants (we use a threshold of 10). The gene has 24 curated benign missense variants. Trascript score misZ: 3.3227 (above the threshold of 3.09). GenCC associations: The gene is linked to progressive familial intrahepatic cholestasis type 1, cholestasis, intrahepatic, of pregnancy, 1.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.786
