Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads IFNA14 as an antibody target. Whether an autoantibody or antibody against IFNA14 could matter depends on whether native IFNA14 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

IFNA14 is annotated as secreted, so native IFNA14 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label IFNA14 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
