Ebert and Stephanie Halene) Mutations affecting the spliceosomal protein U2AF1 are commonly addition, U2AF1(S34F) is present at high allelic frequencies (nearly found in myelodysplastic syndromes (MDS) and secondary acute 50%) in MDS (6), seems to predispose MDS patients to secondary myeloid leukemia (sAML).
