In this study, we found that the diversity of TRA and TRB in CML patients was lower than that reported in healthy individuals, suggesting a possible increase in T‐cell clonality in CML patients; however, the median age of healthy individuals in previous studies was 31.5 years [24], whereas the median age in this study was 64 years. Here, THRB is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
