Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PP2PP3_ModerateBS2
The NM_002471.4(MYH6):c.3163C>T(p.Arg1055Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000479 in 1,461,888 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1055Q) has been classified as Likely benign.

Hypertrophic cardiomyopathy 14 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 17, 2022 | 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MYH6 protein function. ClinVar contains an entry for this variant (Variation ID: 568290). This variant has not been reported in the literature in individuals affected with MYH6-related conditions. This variant is present in population databases (rs764909774, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1055 of the MYH6 protein (p.Arg1055Trp). - |
