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]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 90 of the ACADS protein (p.Gly90Ser). This variant is present in population databases (rs121908005, gnomAD 0.006%). This missense change has been observed in individual(s) with short-chain acyl-coA dehydrogenase (SCAD) deficiency (PMID: 11134486). ClinVar contains an entry for this variant (Variation ID: 3832). 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%. Experimental studies have shown that this missense change affects ACADS function (PMID: 11134486). 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.
