Biochemical markers for inflammatory bowel disease (pANCA and ASCA) [68] and celiac disease (anti-tissue transglutaminase antibody) [21], [69] were examined in our marmosets in an attempt to define the nature of BGS, but unfortunately the marmosets’ serum did not cross-react with the human diagnostic tests (Table S2). The gene discussed is TGM2; the disease is celiac disease.
