Clinical information:

SF3B1 mutations occur in 10-15% of CLL patients and serve as independent predictors of shortened time to treatment and poorer overall survival in CLL. Mutations are also detected in approximately 28% of MDS and 19% of myelodysplastic/myeloproliferative neoplasms. In MDS/MPN, most mutations were found in refractory anemia with ring sideroblasts (the RARS subtype).
