Labcorp Genetics (formerly Invitae), Labcorp RCV001960298 SCV002226279 uncertain significance Gastrointestinal stromal tumor; Paragangliomas 3 2021-08-07 criteria provided, single submitter clinical testing 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 expected to disrupt SDHC protein function. This variant has not been reported in the literature in individuals affected with SDHC-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with cysteine at codon 142 of the SDHC protein (p.Gly142Cys). The glycine residue is moderately conserved and there is a large physicochemical difference between glycine and cysteine.
