In addition, the incidence of genetic mutations in TNFRSF14, TBL1XR1, and P2RY8 was reduced in GI-DLBCL compared with those in non-gastrointestinal DLBCL; however, the differences between the two were not statistically significant (Supplementary Table 3). This evidence concerns the gene TNFRSF14 and diffuse large B-cell lymphoma.
