OverviewNCBI Gene

This gene encodes D-2hydroxyglutarate dehydrogenase, a mitochondrial enzyme belonging to the FAD-binding oxidoreductase/transferase type 4 family. This enzyme, which is most active in liver and kidney but also active in heart and brain, converts D-2-hydroxyglutarate to 2-ketoglutarate. Mutations in this gene are present in D-2-hydroxyglutaric aciduria, a rare recessive neurometabolic disorder causing developmental delay, epilepsy, hypotonia, and dysmorphic features.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against D2HGDH 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 D2HGDH as an antibody target. Whether an autoantibody or antibody against D2HGDH could matter depends on whether native D2HGDH is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

D2HGDH 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 D2HGDH as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
