RCV003813011 | SCV004609374 | uncertain significance | Gastrointestinal stromal tumor; Paragangliomas 4; Pheochromocytoma | 2023-11-11 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with threonine, which is neutral and polar, at codon 91 of the SDHB protein (p.Arg91Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SDHB-related conditions. 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 with a positive predictive value of 80%. 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. |
