RCV001909660 | SCV002183144 | uncertain significance | Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 | 2021-08-03 | 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. This variant has not been reported in the literature in individuals affected with SDHA-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with serine at codon 197 of the SDHA protein (p.Gly197Ser). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and serine. |
