Labcorp Genetics (formerly Invitae), Labcorp RCV001247485 SCV001420910 uncertain significance Gastrointestinal stromal tumor; Paragangliomas 4; Pheochromocytoma 2022-09-13 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). ClinVar contains an entry for this variant (Variation ID: 971655). This variant has not been reported in the literature in individuals affected with SDHB-related conditions. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This sequence change replaces lysine, which is basic and polar, with threonine, which is neutral and polar, at codon 167 of the SDHB protein (p.Lys167Thr).
