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.

STAMBPL1 (HGNC:24105): (STAM binding protein like 1) Predicted to enable Lys63-specific deubiquitinase activity and thiol-dependent deubiquitinase. Predicted to be involved in protein K63-linked deubiquitination. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACTA2-AS1 (HGNC:45169): (ACTA2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).
• BP6: Variant 10-88935118-C-A is Benign according to our data. Variant chr10-88935118-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 301504.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00065 (99/152236) while in subpopulation NFE AF = 0.000706 (48/68014). AF 95% confidence interval is 0.000547. There are 0 homozygotes in GnomAd4. There are 52 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 99 AD,Unknown gene.
