However, while MYF6 expression as reported by Basso et al. [28, 29] was lower in CLL than in HCL, CLL was higher than nearly all other non-HCL malignancies, and this is consistent with our data showing that 73% of CLL patients were MYF6+ by RQ-PCR. Here, MYF6 is linked to B-cell chronic lymphocytic leukemia.
