One of the two CD cases with remaining enteropathy on a GFD that were misclassified based on anti-TG2 (see Clinical antibody tests) showed a level of the TNFRSF9 mRNA marker for normalized CD (Figure 1) that was below the 80% CR of the group with normalized CD and within the 80% CR for the group with active CD (Additional file 2). Here, TNFRSF9 is linked to Abnormal intestine morphology.
