To determine their specificity, six of the CC biomarkers identified in Figure 3: CTAG1A, LYZL6, SCP2D1, TEX33, TKTL2, and SPZ1 were screened for expression in five samples of chronic myeloid leukemia (CML), three samples of chronic lymphoblastic leukemia (CLL), and eight samples of BC isolated from the Saudi population. The gene discussed is LYZL6; the disease is B-cell chronic lymphocytic leukemia.
