GeneDx RCV000158074 SCV000208009 uncertain significance not provided 2017-10-16 criteria provided, single submitter clinical testing The D430N variant has not been published as pathogenic or been reported as benign to our knowledge. The D430N variant is not observed in large population cohorts (Lek et al., 2016). The D430N variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function.
Invitae RCV003748189 SCV004499962 uncertain significance Hypertrophic cardiomyopathy 2023-02-27 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 430 of the MYBPC3 protein (p.Asp430Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MYBPC3-related conditions. ClinVar contains an entry for this variant (Variation ID: 180928). 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 disruptive. 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.
