Variant summary
Our verdict is Pathogenic. The variant received 21 ACMG points: 21P and 0B. PS1_Very_StrongPM1PM5PP2PP5_Very_Strong
The NM_000017.4(ACADS):c.989G>A(p.Arg330His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000139 in 1,613,856 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R330C) has been classified as Likely pathogenic.

Deficiency of butyryl-CoA dehydrogenase Pathogenic:4Uncertain:1
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 330 of the ACADS protein (p.Arg330His). This variant is present in population databases (rs199633532, gnomAD 0.02%). This missense change has been observed in individuals with short-chain acyl-coenzyme A dehydrogenase deficiency (PMID: 16926354, 26274329; Invitae). ClinVar contains an entry for this variant (Variation ID: 557389). 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) has been performed at Invitae 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. This variant disrupts the p.Arg330 amino acid residue in ACADS. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16926354, 18676165; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
