Invitae RCV000456572 SCV000554010 uncertain significance Gastrointestinal stroma tumor; Paragangliomas 4; Pheochromocytoma 2018-11-08 criteria provided, single submitter clinical testing This sequence change replaces arginine with cysteine at codon 38 of the SDHB protein (p.Arg38Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs202119350, ExAC 0.009%). This variant has been reported in individuals affected with paraganglioma (PMID: 23660872, Invitae). ClinVar contains an entry for this variant (Variation ID: 371801). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies. 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.
