Baylor Genetics RCV001329259 SCV001520645 likely pathogenic Multiple acyl-CoA dehydrogenase deficiency 2020-08-01 criteria provided, single submitter clinical testing This variant was determined to be likely pathogenic according to ACMG Guidelines, 2015 [PMID:25741868].
Invitae RCV001329259 SCV002294099 uncertain significance Multiple acyl-CoA dehydrogenase deficiency 2022-07-19 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 262 of the ETFDH protein (p.Leu262Phe). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with glutaric acidemia type II (PMID: 12359134). ClinVar contains an entry for this variant (Variation ID: 1028249). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ETFDH protein function. Studies have shown that this missense change alters ETFDH gene expression (PMID: 12359134). 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.
