Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP3_ModeratePP5_Moderate
The NM_000432.4(MYL2):c.497A>T(p.Asp166Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D166N) has been classified as Uncertain significance.

Hypertrophic cardiomyopathy 10 Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 27, 2022 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this missense change affects MYL2 function (PMID: 18987303, 23727233, 24374283). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 31769). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 12707239; Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 166 of the MYL2 protein (p.Asp166Val). - |
