OverviewNCBI Gene
This gene encodes a mitochondrial solute carrier protein family member. It functions in promoting mitochondrial fission, and prevents the formation of hyperfilamentous mitochondria. Mutation of this gene results in neuropathy and optic atrophy. [provided by RefSeq, Aug 2016]

Whether an antibody against SLC25A46 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 SLC25A46 as an antibody target. Whether an autoantibody or antibody against SLC25A46 could matter depends on whether native SLC25A46 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLC25A46 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 SLC25A46 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
