RCV001242993 | SCV001416121 | uncertain significance | Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 | 2019-10-17 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces cysteine with tyrosine at codon 536 of the SDHA protein (p.Cys536Tyr). The cysteine residue is moderately conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant has not been reported in the literature in individuals with SDHA-related conditions. 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). |
