OverviewNCBI Gene
This gene encodes a calcium-binding mitochondrial carrier protein. The encoded protein localizes to the mitochondria and is involved in the exchange of aspartate for glutamate across the inner mitochondrial membrane. Polymorphisms in this gene may be associated with autism, and mutations in this gene may also be a cause of global cerebral hypomyelination. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Apr 2012]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SLC25A12 as an antibody target. Whether an autoantibody or antibody against SLC25A12 could matter depends on whether native SLC25A12 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLC25A12 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 SLC25A12 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
