Characterization of the CBir1 antigenic response for diagnosis and treatment of Crohn's disease

摘要

This invention provides methods of diagnosing or predicting susceptibility to Crohn's Disease by determining the presence or absence of genetic variants. In one embodiment, the present invention provides methods to diagnose and/or predict susceptibility to Crohn's Disease in an individual by determining the presence or absence of anti-Cbir1 reactivity and the presence or absence of TLR5 risk variants. In another embodiment, the present invention provides methods to diagnose Crohn's Disease by determining the presence or absence of NFKB1 haplotype H3 and/or ASCA expression. In another embodiment, the present invention provides methods of diagnosing Crohn's Disease by determining the presence or absence of Cbir1 specific peripheral blood T cell proliferation.
