We also noted that (a) GSTT2 was differentially expressed in AAs compared with White individuals regardless of whether they were healthy or had BE or EAC (Supplemental Figure 9B), and (b) GSTT2 inversely correlates with the EAC signature (Supplemental Figure 9C) and its subset of neutrophil degranulation signature (Supplemental Figure 9D). Here, GSTT2 is linked to Barrett esophagus.
