Invitae | RCV000816683 | SCV000957201 | uncertain significance | Multiple acyl-CoA dehydrogenase deficiency | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with glutamic acid at codon 269 of the ETFDH protein (p.Gln269Glu). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with ETFDH-related conditions. 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant disrupts the p.Gln269 amino acid residue in ETFDH. Other variant(s) that disrupt this residue have been observed in individuals with ETFDH-related conditions (PMID: 12815589, 24516753), which suggests that this may be a clinically significant amino acid residue. 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. |
