Our results are in line with previous studies reporting that mutations of EZH2 are rare in T-NHL: one in 36 cases (2.7%) in PTCL-NOS and one AITL case in 84 cases (1.2%) in a cohort consisting of AITL, PTCL-NOS, ALCL, and MEITL presented as nonsynonymous single nucleotide variants (SNV) [21]. The gene discussed is EZH2; the disease is mature T-cell and NK-cell non-Hodgkin lymphoma.
