Invitae | RCV003121743 | SCV003788910 | uncertain significance | L-2-hydroxyglutaric aciduria | 2022-06-12 | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 0.006%). This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 448 of the L2HGDH protein (p.Ala448Pro). |
