Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ACADM gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Acyl-CoA dehydrogenase specific for acyl chain lengths of 4 to 16 that catalyzes the initial step of fatty acid beta- oxidation. Utilizes the electron transfer flavoprotein (ETF) as an electron acceptor to transfer electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase). {ECO:0000269|PubMed:25416781}.
• Disease: DISEASE: Acyl-CoA dehydrogenase medium-chain deficiency (ACADMD) [MIM:201450]: An inborn error of mitochondrial fatty acid beta- oxidation which causes fasting hypoglycemia, hepatic dysfunction and encephalopathy, often resulting in death in infancy. {ECO:0000269|PubMed:10767181, ECO:0000269|PubMed:11349232, ECO:0000269|PubMed:11409868, ECO:0000269|PubMed:11486912, ECO:0000269|PubMed:1363805, ECO:0000269|PubMed:1671131, ECO:0000269|PubMed:1684086, ECO:0000269|PubMed:1902818, ECO:0000269|PubMed:2251268, ECO:0000269|PubMed:2393404, ECO:0000269|PubMed:2394825, ECO:0000269|PubMed:7603790, ECO:0000269|PubMed:7929823, ECO:0000269|PubMed:8198141, ECO:0000269|PubMed:9158144, ECO:0000269|PubMed:9882619}.
