Abstract
- Spliceosomal mutations account for the most frequent class of mutations in patients with MDS and CMML, yet the mechanism by which these mutations perform their driver function is not well understood. Moreover, no genetically engineered murine models for expression of spliceosomal gene mutations from their endogenous loci have been reported. Given the genetic heterogeneity of primary patient samples, we generated a model for conditional expression of the commonly occurring SRSF2P95H mutation from the endogenous murine locus of Srsf2. We compared expression of the Srsf2P95H mutation with genetic inactivation of 0, 1 or 2 copies of Srsf2to understand the biological and mechanistic consequences of spliceosomal mutations relative to loss-of-function.
