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

The ACADS c.1095G>T; p.Gln365His variant (rs368469075) is reported in the literature in individuals affected with deficiency of short-chain Acyl-CoA dehydrogenase (Jethva 2008, Pendersen 2008, Pena 2012, Sadat 2020, Seidel 2003, Waisbren 2013). This variant is also reported in ClinVar (Variation ID: 203560). This variant is found in the general population with an overall allele frequency of 0.004% (11/278,764 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is deleterious (REVEL: 0.947). In vitro functional analyses demonstrated folding defects and difficulties for the variant protein to form a mature tetrameric enzyme (Pendersen 2003, Seidel 2003). Based on available information, this variant is considered to be pathogenic. References: Jethva R et al.

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ACADS c.1095G>T (p.Gln365His) missense variant has been reported in two studies in which it is found in a compound heterozygous state with another missense variant in two probands with short-chain acyl-coA dehydrogenase (SCAD) deficiency (Seidel et al. 2003; Pedersen et al. 2008). The p.Gln365His variant was absent from 100 control alleles and is reported at a frequency of 0.000128 in the African population of the Genome Aggregation Database. Functional studies in vitro revealed that the p.Gln365His variant was found to translate and import into mitochondria efficiently but had a decreased ability to form the mature tetrameric enzyme leading to misfolding, and a severe increased tendency to form aggregates especially at an elevated temperature (Seidel et al. 2003; Pedersen et al. 2008). Based on the evidence, the p.Gln365His variant is classified as likely pathogenic for short-chain acyl-coA dehydrogenase deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 365 of the ACADS protein (p.Gln365His). This variant is present in population databases (rs368469075, gnomAD 0.01%). This missense change has been observed in individuals with short-chain acyl-coenzyme A dehydrogenase deficiency (PMID: 12872838, 31813752; Invitae). This variant is also known as Gln341His. ClinVar contains an entry for this variant (Variation ID: 203560). 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) performed at Invitae indicates that this missense variant is not expected to disrupt ACADS protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects ACADS function (PMID: 14506246). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

Functional analysis of Q365H found that it is associated with reduced tetramer formation, increased aggregation tendency, and increased chaperone retention compared to wild-type, similar to other pathogenic variants in the ACADS gene (Seidel et al., 2003; Pedersen et al., 2008); Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 12872838, 18523805, 31813752, 23798014, 22241096, 18951053, 14506246) -
