Genes affected

ACADM (HGNC:89): (acyl-CoA dehydrogenase medium chain) This gene encodes the medium-chain specific (C4 to C12 straight chain) acyl-Coenzyme A dehydrogenase. The homotetramer enzyme catalyzes the initial step of the mitochondrial fatty acid beta-oxidation pathway. Defects in this gene cause medium-chain acyl-CoA dehydrogenase deficiency, a disease characterized by hepatic dysfunction, fasting hypoglycemia, and encephalopathy, which can result in infantile death. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PM1

In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_001286043.2

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 95 curated pathogenic missense variants (we use a threshold of 10). The gene has 29 curated benign missense variants. Gene score misZ: 0.54287 (below the threshold of 3.09). Trascript score misZ: 0.50796 (below the threshold of 3.09). GenCC associations: The gene is linked to medium chain acyl-CoA dehydrogenase deficiency.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.974

PP5

Variant 1-75740069-T-A is Pathogenic according to our data. Variant chr1-75740069-T-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 198379.
