Briefly, the TB was estimated for each of the BM/PB specimens involved by the lymphomas (16 AITL and 1 PTCL-NOS) based on their histological, immunophenotyping, and T-cell receptor gamma (TCRG) gene rearrangement findings (Supplementary file 1), and compared to the VAFs of the somatic alterations of T-cell lymphoma-associated genes, for example, RHOA p.G17V, a molecular characteristic of AITL (Nakamoto-Matsubara et al., 2014; Sakata-Yanagimoto et al., 2014; Tiacci et al., 2018; Yoo et al., 2014). This evidence concerns the gene TRGC1 and mature T-cell and NK-cell non-Hodgkin lymphoma.
