NM_000017.4:c.842G>C

Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM1PM2PP2PP3_Strong

The NM_000017.4(ACADS):​c.842G>C​(p.Gly281Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000167 in 1,612,488 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G281V) has been classified as Uncertain significance.

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]
ACADS Gene-Disease associations (from GenCC):
  • short chain acyl-CoA dehydrogenase deficiency

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1
In a helix (size 36) in uniprot entity ACADS_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_000017.4
PM2
Very rare variant in population databases, with high coverage;
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, 0.991
