OverviewNCBI Gene
This gene is a member of the homeobox family of genes that encode proteins containing a 60-amino acid residue motif that represents a DNA binding domain. Homeobox genes have been characterized extensively as transcriptional regulators involved in pattern formation in both invertebrate and vertebrate species. Several human genetic disorders are caused by aberrations in human homeobox genes. This locus represents a pseudoautosomal homeobox gene that is thought to be responsible for idiopathic short stature, and it is implicated in the short stature phenotype of Turner syndrome patients. This gene is considered to be a candidate gene for Cornelia de Lange syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SHOX2 as an antibody target. Whether an autoantibody or antibody against SHOX2 could matter depends on whether native SHOX2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SHOX2 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 SHOX2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
