Moreover, nine biopsies (3.96%) showed coeliac disease-related laboratory results: five (2.20%) exhibited clear positive findings for both tissue transglutaminase IgA (tTG) and endomysial antibody (EMA), while four cases (1.76%) had a positive IgA tTG result with a negative or missing EMA result (Table 4). Here, TGM2 is linked to celiac disease.
