Abnormal mRNAs of the hybrid BCR-ABL gene in the majority of cases initiate the synthesis of proteins with a mass of 210 kDa (p210), 190 kDa (p190), and 230 kDa (p230). Expression of the p210 variant is most common in CML (95% of cases), while the p190 and p230 variants are less common (1-4%). On the contrary, p190 predominates in ALL.

A number of mutations in the JAK2 gene act as driving forces of myeloproliferative neoplasms (MPN), the pathogenesis of certain variants of acute leukemia, a number of solid malignancies and cardiovascular diseases. Assays for quantifying JAK2 mRNA in circulating blood cells can be used as a marker associated with the activity of this enzyme.

Increased expression of miR-155 is observed in many malignant diseases, including lymphomas, acute myeloid leukemia and CLL. However, a comparative study of the miR-155 expression in the blood leukocytes in patients with chronic myeloid and lymphoproliferative diseases has not yet been carried out.
