Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads FEM1C as an antibody target. Whether an autoantibody or antibody against FEM1C could matter depends on whether native FEM1C is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
FEM1C 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 FEM1C as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
