Splicing factor mutations in hematologic malignancies.

ABSTRACT: Mutations in genes encoding RNA splicing factors were discovered nearly 10 years ago and are now understood to be among the most recurrent genetic abnormalities in patients with all forms of myeloid neoplasms and several types of lymphoproliferative disorders, as well as subjects with clonal hematopoiesis. These discoveries implicate aberrant RNA splicing, the process by which precursor RNA is converted into mature messenger RNA, in the development of clonal hematopoietic conditions. Both the protein and the RNA components of the splicing machinery are affected by mutations at highly specific residues, and a number of these mutations alter splicing in a manner distinct from loss of function. Importantly, cells bearing these mutations have now been shown to generate mRNA species with novel
