Serine/arginine-rich splicing factor 2 (SRSF2) is a gene that codes for one of several serine/arginine-rich splicing factors, serine/arginine-rich splicing factor 2. SRSF2 is a member of the spliceosome and is involved in mRNA processing (Gene 2014). Spliceosome mutations are observed in MDS, chronic lymphocytic leukemia (CLL), AML, and chronic myelomonocytic leukemia (CMML), and these mutations can cause abnormal expression patterns of some genes involved in cancer pathogenesis (PMID: 23327988).

SRSF2 is altered in 1.62% of all cancers with acute myeloid leukemia, myelodysplastic syndromes, acute myeloid leukemia with myelodysplasia-related changes, breast invasive ductal carcinoma, and chronic myelomonocytic leukemia having the greatest prevalence of alterations [3].

The most common alterations in SRSF2 are SRSF2 Mutation (1.33%), SRSF2 Exon 1 Mutation (1.15%), SRSF2 Codon 95 Missense (0.86%), SRSF2 P95H (0.72%), and SRSF2 P95L (0.26%) [3].
