The volcano plot of Figure 3C shows that CeD‐SBAs shared an expression profile similar to that of UCD mucosae, with only TET1 and TET2 transcripts being significantly downregulated (p = 0.0081 and p = 0.0085, respectively) and CD4 and IL6 transcripts significantly upregulated (p = 0.033 and p = 0.0287, respectively) in CeD‐SBAs compared with UCD mucosae. The gene discussed is CD4; the disease is urea cycle disorder.
