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
Feb 03, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. 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 expected to disrupt ACADS protein function. ClinVar contains an entry for this variant (Variation ID: 549997). This missense change has been observed in individual(s) with short chain acyl-CoA dehydrogenase deficiency (PMID: 27466294, 27938594). This variant is present in population databases (rs755247580, gnomAD 0.03%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 228 of the ACADS protein (p.Glu228Lys). -
