OverviewNCBI Gene

This gene encodes an enzyme involved in the catabolism of choline, catalyzing the oxidative demethylation of dimethylglycine to form sarcosine. The enzyme is found as a monomer in the mitochondrial matrix, and uses flavin adenine dinucleotide and folate as cofactors. Mutation in this gene causes dimethylglycine dehydrogenase deficiency, characterized by a fishlike body odor, chronic muscle fatigue, and elevated levels of the muscle form of creatine kinase in serum. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against DMGDH can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads DMGDH as an antibody target. Whether an autoantibody or antibody against DMGDH could matter depends on whether native DMGDH is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DMGDH is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label DMGDH as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
