OverviewNCBI Gene

This gene encodes a proline-rich protein that contains two A-T hook DNA binding domains. A chromosomal translocation and gene fusion between this gene and zinc finger, MIZ-type containing 1 (Gene ID: 57178) may underlie intellectual disability and neuropsychiatric problems in a human patient. Enriched expression of this gene in embryonic mouse brain suggests that this gene may play a role in nervous system development. [provided by RefSeq, Jul 2016]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads PRR12 as an antibody target. Whether an autoantibody or antibody against PRR12 could matter depends on whether native PRR12 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PRR12 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 PRR12 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
