ClinVar

Description

ClinVar contains an entry for this variant (Variation ID: 2055479). This variant has not been reported in the literature in individuals affected with MYH3-related conditions. This variant is present in population databases (rs773153080, gnomAD 0.009%). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 906 of the MYH3 protein (p.Cys906Tyr). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MYH3 protein function. 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.
