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]

The variant is present at low allele frequencies population databases (rs28940875 – gnomAD 0.0003941%; ABraOM no frequency - http://abraom.ib.usp.br/) - PM2_supporting. The p.(Arg380Trp) was detected in trans with a pathogenic variant (PMID: 24485985; 22424739; 16926354) - PM3. Multiple lines of computational evidence support a deleterious effect on the gene or gene product - PP3. In summary, the currently available evidence indicates that the variant is likely pathogenic. -

Variant summary: ACADS c.1138C>T (p.Arg380Trp) results in a non-conservative amino acid change in 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 9.3e-05 in 248232 control chromosomes (gnomAD). c.1138C>T has been reported in the literature in multiple individuals affected with short-chain acyl-CoA dehydrogenase (SCAD) deficiency (examples: Bok_2003, Edhager_2014, Navarrete_2019). These data indicate that the variant is very likely to be associated with disease. Multiple publications have reported experimental evidence that this variant changes the normal protein function (examples: Edhager_2014, Bok_2003). The following publications have been ascertained in the context of this evaluation (PMID: 24485985, 30626930, 18523805, 14595061). Ten submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 380 of the ACADS protein (p.Arg380Trp). This variant is present in population databases (rs28940875, gnomAD 0.05%). This missense change has been observed in individuals with SCAD deficiency (PMID: 11134486, 14595061, 16906473, 16926354, 22424739, 24485985). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 3837). 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) has been performed 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. Experimental studies have shown that this missense change affects ACADS function (PMID: 18523805). For these reasons, this variant has been classified as Pathogenic. -
