Labcorp Genetics (formerly Invitae), Labcorp RCV000648302 SCV000770116 uncertain significance Hypertrophic cardiomyopathy 11; Dilated cardiomyopathy 1R; Atrial septal defect 5 2024-11-04 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 4 of the ACTC1 protein (p.Asp4Asn). This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ACTC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 538810). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002424493 SCV002742833 uncertain significance Cardiovascular phenotype 2019-11-01 criteria provided, single submitter clinical testing The p.D4N variant (also known as c.10G>A), located in coding exon 1 of the ACTC1 gene, results from a G to A substitution at nucleotide position 10. The aspartic acid at codon 4 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
