OverviewNCBI Gene

This gene encodes a mitochondrially localized protein that is highly conserved across species. The gene is expressed in a variety of tissues including human lymphoblast cells and rat neurosensorial epithelium of the cristaampullaris. A mutation in this gene has been associated with familial Meniere's disease, a chronic disorder of the inner ear. Several pseudogenes of this gene are found on other chromosomes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2016]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FAM136A 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 FAM136A as an antibody target. Whether an autoantibody or antibody against FAM136A could matter depends on whether native FAM136A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FAM136A 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 FAM136A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
