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]

Variant summary: ACADS c.814C>T (p.Arg272Cys) results in a non-conservative amino acid change to a highly conserved residue (HGMD) located in the Acyl-CoA dehydrogenase/oxidase, C-terminal domain (IPR009075) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 247630 control chromosomes (gnomAD). c.814C>T has been reported in the literature in individuals affected with Deficiency Of Butyryl-CoA Dehydrogenase (Tonin_2016, Huang_2016). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 27051597, 33895855, 27938594). Five submitters have cited clinical-significance assessments for this variant to ClinVar after 2014, and classified it as likely pathogenic (n=4) or uncertain significance (n=1). Based on the evidence outlined above, the variant was classified as likely pathogenic. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 272 of the ACADS protein (p.Arg272Cys). This variant is present in population databases (rs539219309, gnomAD 0.008%). This missense change has been observed in individuals with short-chain acyl-coenzyme A dehydrogenase deficiency (PMID: 27051597; internal data). ClinVar contains an entry for this variant (Variation ID: 377422). 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 ACADS protein function with a positive predictive value of 95%. This variant disrupts the p.Arg272 amino acid residue in ACADS. Other variant(s) that disrupt this residue have been observed in individuals with ACADS-related conditions (PMID: 32710939), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -
