Labcorp Genetics (formerly Invitae), Labcorp RCV003624807 SCV004394838 likely pathogenic Multiple acyl-CoA dehydrogenase deficiency 2024-09-23 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 594 of the ETFDH protein (p.Ile594Thr). This variant is present in population databases (rs770051042, gnomAD 0.003%). This missense change has been observed in individual(s) with multiple Acyl-CoA dehydrogenase deficiency (internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ETFDH protein function with a positive predictive value of 80%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
