Genes affected

PHACTR1 (HGNC:20990): (phosphatase and actin regulator 1) The protein encoded by this gene is a member of the phosphatase and actin regulator family of proteins. This family member can bind actin and regulate the reorganization of the actin cytoskeleton. It plays a role in tubule formation and in endothelial cell survival. Polymorphisms in this gene are associated with susceptibility to myocardial infarction, coronary artery disease and cervical artery dissection. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PHACTR1. . Gene score misZ 0.708 (greater than the threshold 3.09). Trascript score misZ 3.1944 (greater than threshold 3.09). GenCC has associacion of gene with West syndrome, developmental and epileptic encephalopathy, 70.
