dbSNP rs932525260: ACADS:p.Arg325Gln (chr12-120738860-G-A) – ACMG Classification: Pathogenic (13 pts)

Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate

The NM_000017.4(ACADS):c.974G>A(p.Arg325Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000821 in 1,461,230 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R325W) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PM1

In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_000017.4

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-120738859-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 3835.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 27 curated pathogenic missense variants (we use a threshold of 10). The gene has 8 curated benign missense variants. Gene score misZ: 0.58444 (below the threshold of 3.09). Trascript score misZ: 0.78549 (below the threshold of 3.09). GenCC associations: The gene is linked to short chain acyl-CoA dehydrogenase deficiency.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.979

PP5

Variant 12-120738860-G-A is Pathogenic according to our data. Variant chr12-120738860-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 450631.Status of the report is criteria_provided_single_submitter, 1 stars.
