Variant summary

Our verdict is The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_001141945.3(ACTA2):c.-24+733T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: NM_001141945.3 is not a MANE Select or MANE Plus Clinical transcript for ACTA2; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant allele was found at a cumulative frequency of 0.536 (AC=81,523) in the gnomAD database across 152,064 control chromosomes, including 22,963 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.714. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Variant has been reported in ClinVar as Benign/Likely Benign (★).

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.

FAS (HGNC:11920): (Fas cell surface death receptor) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor contains a death domain. It has been shown to play a central role in the physiological regulation of programmed cell death, and has been implicated in the pathogenesis of various malignancies and diseases of the immune system. The interaction of this receptor with its ligand allows the formation of a death-inducing signaling complex that includes Fas-associated death domain protein (FADD), caspase 8, and caspase 10. The autoproteolytic processing of the caspases in the complex triggers a downstream caspase cascade, and leads to apoptosis. This receptor has been also shown to activate NF-kappaB, MAPK3/ERK1, and MAPK8/JNK, and is found to be involved in transducing the proliferating signals in normal diploid fibroblast and T cells. Several alternatively spliced transcript variants have been described, some of which are candidates for nonsense-mediated mRNA decay (NMD). The isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full length isoform. [provided by RefSeq, Mar 2011]
