In this study, we analyzed the expression level of all three genes in samples from Chinese patients with T cell NHL (T-NHL), B cell NHL (B-NHL), and NK/T cell lymphoma (NK/T-CL) to further understand the role of A20 and the NF-κB pathway in the occurrence and development of lymphoma. Here, TNFAIP3 is linked to T-cell non-Hodgkin lymphoma.
