Invitae RCV000497441 SCV000623549 uncertain significance Hypertrophic cardiomyopathy 2018-12-04 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with asparagine at codon 75 of the MYBPC3 protein (p.Asp75Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs375471260, ExAC 0.02%). This variant has been reported in individuals with hypertrophic cardiomyopathy (HCM) (PMID: 21943931, 27600940, 21488259) and in a family with suggestive electrocardiographic alterations but no diagnoses of HCM. ClinVar contains an entry for this variant (Variation ID: 161313). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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.
