Other markers associated with celiac disease like elevated serum anti-gliadin and/or anti-tissue transglutaminase (anti-TTG) IgG or elevated succus anti-gliadin and/or anti-TTG IgA antibodies were also associated with a response to GFD indicating that potential or latent celiac disease could be present in this cohort. The gene discussed is CD79A; the disease is celiac disease.
