Invitae RCV000459530 SCV000551317 uncertain significance Pyridoxine-dependent epilepsy 2016-05-22 criteria provided, single submitter clinical testing This sequence change replaces valine with methionine at codon 228 of the ALDH7A1 protein (p.Val228Met). The valine residue is highly conserved and there is a small physicochemical difference between valine and methionine. This variant is present in population databases (rs201832111, ExAC 0.01%) but has not been reported in the literature in individuals with a ALDH7A1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
