Figure 5. DHTKD1 protein expression in family 443.

IHC staining for dehydrogenase E1 and transketolase domain–containing 1 (DHTKD1) expression in esophageal biopsies from normal controls (NL), unrelated patients with active EoE, and individual II.2 from family 443 during active disease (active) and disease remission (inactive). Images from 2 patients are shown for both the NL and unrelated active EoE groups (representative of 6 patients per group). Scale bar: 50 μM.
