OverviewNCBI Gene

The protein encoded by this gene belongs to the HMG-CoA lyase family. It is a mitochondrial enzyme that catalyzes the final step of leucine degradation and plays a key role in ketone body formation. Mutations in this gene are associated with HMG-CoA lyase deficiency. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

LocalizationUniProt · AlphaFold · HPA

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

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