The lymph node biopsy revealed five rearrangementsof the TCRG gene and eight of the TCRB genes.Except for the rearrangements of TCRB (A), 267 bp, andTCRB (B), 262 bp, that are present in most tissuessimultaneously, other rearrangements of TCRB genes wererandomly distributed and belonged to different tumor clones. The gene discussed is TRGC1; the disease is neoplasm.
