OverviewNCBI Gene
This gene is a member of a phylogenetically conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of developmental processes. Mutations in this gene have been associated with the inherited X-linked disorder, Cleft palate with ankyloglossia, and it is believed to play a major role in human palatogenesis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads TBX22 as an antibody target. Whether an autoantibody or antibody against TBX22 could matter depends on whether native TBX22 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TBX22 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 TBX22 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
