Congenital erythrocytosis: a new form associated with an erythropoietin-dependent mechanism.

abstract：:The identification of acquired CALR mutations in patients with essential thrombocythaemia (ET) or myelofibrosis (MF) has meant that disease-initiating mutations can now be detected in about 90% of all patients with a myeloproliferative neoplasm (MPN). Here, we show that only those CALR mutations that cause a +1 frames...
