Gene: [01p31/ACADM] acyl-CoA dehydrogenase M (medium straight-chain fa C4/C12); hypoglycemia, non-ketotic, and secondary carnitine deficiency; dicarboxylicaciduria (MCAD deficiency); Reye-like syndrome (fatty acids beta-oxidation familial defect);

[1] Systematic name: acyl-CoA:(acceptor) 2,3-oxidoreductase.
[2] Reaction catalyzed: Acyl-CoA + ETF = 2,3-dehydroacyl-CoA + reduced ETF. [3] The acyl-CoA dehydrogenase M participates in the initiation of beta-oxidation of medium straight-chain fatty acids (C4-C12), that requires ACADM to bind with another flavoprotein. The latter is composed of 2 subunits, see GEM:15q2/ETFA and GEM:19q134/ETFB." |

The active enzyme is a homotetramer. Each of its four identical subunits is synthesized as ACADM propeptide of MM 50 kD while the mature ACADM peptide has MM 46 kD. The 4 kD difference is due to a leader peptide being cut out after the protein transition from cytosol into mitochondria." |

Genes encoding other enzymes of the acyl-CoA dehydrogenase
group have also been identified. This group includes the enzymes for
short straight-chain (GEM:12q2/ACADS), long
straight-chain
(GEM:02q3/ACADL) and very long straight-chain
fatty acids
(GEM:17p11/ACADVL), as well as the enzymes
dehydrating isovaleryl-CoA
(GEM:15q1/ACADI), glutaryl-CoA (GEM:19p132/GCDH), and
branched-chain substrates with the alpha-methyl group
(2-methyl-butyryl-CoA and isobutyryl-CoA). The latter enzyme is denoted as 2-'ME'BCAD; the corresponding gene is not yet mapped (GEM:00.0/ACADB). All genes of acyl-CoA dehydrogenases are likely to have originated from the same ancestral gene. They form a multigene family, as follows from analysis of the corresponding amino acid and nucleic acid sequences." |

Clinical genetic data on various disturbances of the fatty acid oxidation in mitochondria are not organized systematically. The MIM catalogue describes these disturbances as independent markers: MIM:201450 (corresponding to GEM:01p31/ACADM), MIM:201460 (GEM:02q3/ACADL), MIM:201470 (GEM:12q2/ACADS), MIM:243500 (GEM:15q1/ACADI*), MIM:201475 (GEM:17p11/ACADVL), MIM:231670 (glutaric aciduria I, glutaryl-CoA dehydrogenase deficiency; GEM:19p132/GCDH), MIM:231680 (glutaric aciduria IIA, MADD; GEM:15q2/ETFA), MIM:130410 (glutaric aciduria IIB; GEM:19q134/ETFB), MIM:231675 (glutaric aciduria IIC; GEM:04q3/ETFDH)." |
