By Sanger sequencing, four of 11 large cell PTCL-TFH patients (36%), one of six small cell PTCL-TFH (17%), eight of 19 of AITL (42%), two of four F-TCL (50%) and one of 13 PTCL-NOS (8%) patients showed the RHOA p.G17V mutation (Fig. 3), but no significant differences were found among the groups. The gene discussed is RHOA; the disease is angioimmunoblastic T-cell lymphoma.
