Children with Down's syndrome are at an increased risk for development of several hematological disorders like acute leukemia, acute myelofibrosis of childhood and transient myeloproliferative disorder (TMD)(1). Transient myeloproliferative disorder is recognized shortly after birth or in neonatal period and is characterized by leukocytosis and thrombocytopenia, which resolves spontaneously in ...

BACKGROUND AND OBJECTIVES Detection of chromosomal abnormalities in myeloproliferative disorders is important for proper diagnosis of these disorders. This study has investigated the presence of JAK2 mutation (V617F) in Egyptian patients with myeloproliferative disorders referred to National Cancer institute, Cairo University. METHODS The study involved 110 cases of Philadelphia negative Myel...

Philadelphia-chromosome negative chronic myeloproliferative neoplasms are clonal hematologic diseases characterized by hematopoietic progenitor independence from or hypersensitivity to cytokines. The cellular and molecular mechanisms involved in the pathophysiology of myeloproliferative neoplasms have not yet been fully clarified. Pathophysiologic findings relevant for myeloproliferative neopla...
