Description

This sequence change replaces tyrosine with cysteine at codon 771 of the RBM20 protein (p.Tyr771Cys). The tyrosine residue is moderately conserved and there is a large physicochemical difference between tyrosine and cysteine. 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 not expected to disrupt RBM20 protein function. This variant has not been reported in the literature in individuals with RBM20-related conditions. This variant is not present in population databases (ExAC no frequency).
