Abstract: The present invention concerns the V617F variant of the protein-tyrosine kinase JAK2, said variant being responsible for Vaquez Polyglobulia. The invention also relates to a first intention diagnostic method for erythrocytosis and thrombocytosis allowing their association with myeloproliferative disorders, or to the detection of the JAK2 V617F variant in myeloproliferative disorders allowing their reclassification in a new nosological group.

Abstract: The present invention concerns an in vitro method for diagnosing a myeloid tumour or a lymphoid tumour in a subject, which comprises the step of analyzing a biological sample from said subject by (i) detecting the presence of a mutation in the Ten Eleven Translocation protein family member 2 gene (TET2) coding for the polypeptide having the sequence SEQ ID NO:2, and/or (ii) analyzing the expression of the TET2 gene; wherein the detection of such a TET2 mutation, of the absence of expression of TET2 or of the expression of a truncated TET2 is indicative of a subject developing or predisposed to develop a myeloid tumour or a lymphoid tumour.

Abstract: A regime or regimen for inducing the differentiation of multilineage myeloid progenitor cells (CFU-GEMM) into megakaryocyte progenitor cells and, optionally, into megakaryocytes, that are able to produce platelets both in vivo and in vitro, includes a step a) of administering a thus effective amount of erythropoietin, derivative or agonist thereof to multilinear myeloid progenitor cells.
