Genes affected
ACADS (HGNC:90): (acyl-CoA dehydrogenase short chain) This gene encodes a tetrameric mitochondrial flavoprotein, which is a member of the acyl-CoA dehydrogenase family. This enzyme catalyzes the initial step of the mitochondrial fatty acid beta-oxidation pathway. Mutations in this gene have been associated with short-chain acyl-CoA dehydrogenase (SCAD) deficiency. Alternative splicing results in two variants which encode different isoforms. [provided by RefSeq, Oct 2014]

Deficiency of butyryl-CoA dehydrogenase Pathogenic:4Uncertain:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 330 of the ACADS protein (p.Arg330His). This variant is present in population databases (rs199633532, gnomAD 0.02%). This missense change has been observed in individuals with short-chain acyl-coenzyme A dehydrogenase deficiency (PMID: 16926354, 26274329; Invitae). ClinVar contains an entry for this variant (Variation ID: 557389). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ACADS protein function. This variant disrupts the p.Arg330 amino acid residue in ACADS. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16926354, 18676165; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
