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]

Deficiency of isobutyryl-CoA dehydrogenase

Pathogenic:1Uncertain:1

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 29, 2024	This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 152 of the ACAD8 protein (p.Met152Thr). This variant is present in population databases (rs121908418, gnomAD 0.01%). This missense change has been observed in individual(s) with biochemical features of isobutyryl-CoA dehydrogenase deficiency (PMID: 16857760, 17304052). This variant is also known as p.M130T. ClinVar contains an entry for this variant (Variation ID: 5355). 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 ACAD8 protein function with a positive predictive value of 80%. 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. -
