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 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 13, 2020This sequence change replaces proline with arginine at codon 142 of the ACADS protein (p.Pro142Arg). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual affected with short-chain acyl-CoA dehydrogenase deficiency (SCADD) (PMID: 22424739). ClinVar contains an entry for this variant (Variation ID: 420094). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. -

Uncertain significance, criteria provided, single submitterclinical testingGeneDxFeb 10, 2017The P142R variant has been reported in one patient with short chain acyl-CoA dehydrogenase (SCAD) deficiency. This patient was also found to harbor the c.366_367delCT variant and the c.625 G>A variant. The phase of these three variants is unknown (Gallant et al., 2012). The P142R variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The P142R variant occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. In summary, we interpret P142R to be a variant of uncertain significance. -
