We also observed increased levels of CLC, COL1A2, CTSC, EPPK1, and EPX and lowered levels of ALOX12, ENDOU, and GRPEL2, however, these changes were not EoE-specific in our patient cohort and also occurred in CD and/ or GERD (Fig. EV3A; Dataset EV2C). Here, COL1A2 is linked to eosinophilic esophagitis.
