Invitae | RCV002967297 | SCV003284665 | uncertain significance | L-2-hydroxyglutaric aciduria | 2022-04-12 | 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with L2HGDH-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.04%). This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 41 of the L2HGDH protein (p.Ser41Gly). |
