Description

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 ACTC1 protein function. This variant has not been reported in the literature in individuals affected with ACTC1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 193 of the ACTC1 protein (p.Lys193Arg).
