Insights from a rare myeloproliferative neoplasm with coexisting BCR‐ABL1 fusion gene, CALR, and TET2 mutations treated with nilotinib and ruxolitinib.

Myeloproliferative neoplasms (MPNs) with concurrent BCR‐ABL1 fusion gene and CALR mutation are especially rare. We report a patient with coexisting BCR‐ABL1 fusion gene, CALR, and TET2 mutations who was treated with the combination of the second‐generation TKI nilotinib and JAK1/JAK2 inhibitor ruxolitinib.
