dbSNP rs199633532: ACADS:p.Arg330His (chr12-120738875-G-A) – ACMG Classification: Pathogenic (21 pts)

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.

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 21 ACMG points.

PS1

Transcript NM_000017.4 (ACADS) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000017.4

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-120738874-CGC-TGT is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 203569.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.

PP5

Variant 12-120738875-G-A is Pathogenic according to our data. Variant chr12-120738875-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 557389.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
