Assessing clonal fitness and mechanisms of clonal evolution in FPD-MN
Germline RUNX1 mutations are commonly observed in familial platelet disorders (FPD); FPD patients have a high rate of transformation to myeloid neoplasms (FPD-MN). The molecular pathogenesis of FPD-MN remains elusive.
The proposed research here will use novel mouse models to identify contexts in which oncogenic RUNX1 mutations are necessary for disease progression and maintenance. These studies will provide insights into mechanisms of clonal fitness and leukemic transformation in FPD, which can help identify FPD patients at highest risk of transformation and inform the development of novel therapeutic approaches to prevent/intercept disease progression.
