Inferring the initiation and development of myeloproliferative neoplasms
Résumé
The developmental history of blood cancer begins with mutation acquisition and the resulting malignant clone expansion. The two most prevalent driver mutations found in myeloproliferative neoplasms— JAK2 V617F and CALR m —occur in hematopoietic stem cells, which are highly complex to observe in vivo. To circumvent this difficulty, we propose a method relying on mathematical modeling and statistical inference to determine disease initiation and dynamics. Our findings suggest that CALR m mutations tend to occur later in life than JAK2 V617F . Our results confirm the higher proliferative advantage of the CALR m malignant clone compared to JAK2 V617F . Furthermore, we illustrate how mathematical modeling and Bayesian inference can be used for setting up early screening strategies.
