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 OPA1 protein function. This variant has not been reported in the literature in individuals affected with OPA1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with valine at codon 436 of the OPA1 protein (p.Ile436Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine.
