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 Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, PHACTR1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.852
• PP5: Variant 6-12749749-C-G is Pathogenic according to our data. Variant chr6-12749749-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2584340.Status of the report is criteria_provided_single_submitter, 1 stars.
