Labcorp Genetics (formerly Invitae), Labcorp RCV002032944 SCV002112412 uncertain significance Gastrointestinal stromal tumor; Paragangliomas 4; Pheochromocytoma 2021-04-21 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with SDHB-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with cysteine at codon 184 of the SDHB protein (p.Tyr184Cys). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and cysteine. 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 SDHB protein function. 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.
