Genes affected
ACTG2 (HGNC:145): (actin gamma 2, smooth muscle) Actins are highly conserved proteins that are involved in various types of cell motility and in the maintenance of the cytoskeleton. Three types of actins, alpha, beta and gamma, have been identified in vertebrates. Alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton and as mediators of internal cell motility. This gene encodes actin gamma 2; a smooth muscle actin found in enteric tissues. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Based on similarity to peptide cleavage of related actins, the mature protein of this gene is formed by removal of two N-terminal peptides.[provided by RefSeq, Dec 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PP5
Variant 2-73902698-C-A is Pathogenic according to our data. Variant chr2-73902698-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 218311.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr2-73902698-C-A is described in Lovd as [Pathogenic].
BP4
Computational evidence support a benign effect (MetaRNN=0.068038076). . Strength limited to SUPPORTING due to the PP5.
BS2
High AC in GnomAd4 at 17 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
