[SRSF2 mutation in patients with chronic myelomonocytic leukemia].

Objective: To investigate SRSF2 mutations in patients with chronic myelomonocytic leukemia (CMML) and the clinical characteristics of patients with SRSF2 mutants.

Methods: In this study, the frequency of SRSF2 mutation in a cohort of 20 patients with CMML was detected by polymerase chain reaction (PCR) followed by direct sequencing to couple with their clinical features.

Results: Of 20 patients, 4 patients were found harboring SRSF2 mutations, including 2 P95L, 1 P95H and 1 P95R point mutations. There were no significantly statistical differences in terms of their clinical characteristics between mutant and wild type group.

Conclusion: SRSF2 mutation was not frequently occurred in CMML patients and might associated with poor prognosis. It might be a practically diagnostic maker and therapeutic target in CMML.
