Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 5P and 4B. PP2PP3_StrongBS2

The NM_001613.4(ACTA2):c.1112T>C(p.Ile371Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000744 in 1,613,522 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I371N) has been classified as Uncertain significance.

Genes affected

ACTA2 (HGNC:130): (actin alpha 2, smooth muscle) This gene encodes one of six different actin proteins. Actins are highly conserved proteins that are involved in cell motility, structure, integrity, and intercellular signaling. The encoded protein is a smooth muscle actin that is involved in vascular contractility and blood pressure homeostasis. Mutations in this gene cause a variety of vascular diseases, such as thoracic aortic disease, coronary artery disease, stroke, and Moyamoya disease, as well as multisystemic smooth muscle dysfunction syndrome.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP2

Missense variant in the ACTA2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 27 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Trascript score misZ: 4.6117 (above the threshold of 3.09). GenCC associations: The gene is linked to multisystemic smooth muscle dysfunction syndrome, connective tissue disorder, familial thoracic aortic aneurysm and aortic dissection, Moyamoya disease 5, aortic aneurysm, familial thoracic 6.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.961

BS2

High AC in GnomAdExome4 at 10 AD,Unknown gene.
