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 SDHD protein function. This variant has not been reported in the literature in individuals affected with SDHD-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with leucine at codon 91 of the SDHD protein (p.Met91Leu). The methionine residue is moderately conserved and there is a small physicochemical difference between methionine and leucine.
