One further case was found within the group of patients with functional dyspepsia (1.1%), displaying positivity for both tTG-IgA (value 123 U/mL) and EMA-IgA at 1:16 dilution, thus leading to a definitive diagnosis of CD upon the demonstration of the characteristic lesions at histologic examination of the duodenal biopsies (see Table 2). Here, TGM2 is linked to dyspepsia.
