Genes affected

ACAD8 (HGNC:87): (acyl-CoA dehydrogenase family member 8) This gene encodes a member of the acyl-CoA dehydrogenase family of enzymes that catalyze the dehydrogenation of acyl-CoA derivatives in the metabolism of fatty acids or branch chained amino acids. The encoded protein is a mitochondrial enzyme that functions in catabolism of the branched-chain amino acid valine. Defects in this gene are the cause of isobutyryl-CoA dehydrogenase deficiency.[provided by RefSeq, Nov 2009]

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. 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 not expected to disrupt ACAD8 protein function. ClinVar contains an entry for this variant (Variation ID: 1376818). This variant has not been reported in the literature in individuals affected with ACAD8-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 11 of the ACAD8 protein (p.Ala11Val). -
