The purpose of this study is to examine the relationship of t(11;16)(q23;p13) to the type of myeloproliferative disorder noted by hematopathology. Previously, t(11;16) has been reported in fewer than 20 patients, all with the diagnosis of therapy-related (secondary) acute myelogenous leukemia (sAML) or myelodysplastic syndrome (MDS). Putative involved genes are the MLL on 11q23 and CBP at 16p13...

Background: Acute Myeloid Leukemia (AML) with translocation (3,3) is a form of AML that may present de novo or may arise from a previous myelodysplastic syndrome. It is often associated with normal or elevated peripheral blood platelet count and increased bone marrow megakaryocytes with associated multi lineage dysplasia. A subset of patients present with hepatosplenomegaly while a few cases h...

The MLL gene from human chromosome 11q23 is involved in >30 different chromosomal translocations resulting in a plethora of different MLL fusion proteins. Each of these tends to associate with a specific leukaemia type, for example, MLL-AF9 is found mainly in acute myeloid leukaemia. We have studied the role of the Mll-AF9 gene fusion made in mouse embryonic stem cells by an homologous recombin...

The MLL gene located at 11q23 is frequently disrupted by chromosomal translocation in a wide spectrum of newly diagnosed acute leukemias. Recently, it has become apparent that the MLL gene is very frequently disrupted by chromosomal translocations in patients with secondary leukemias associated with chemotherapeutic regimens incorporating topoisomerase II inhibitors. These secondary leukemias a...

Cytogenetic analyses of pretreatment bone marrows were performed at local institutions as part of Childrens Cancer Group (CCG) protocol CCG-107 for infants less than 1 year of age with previously untreated acute lymphoblastic leukemia (ALL). Cytogenetic analyses from 39 patients (17 males and 22 females) were accepted after review. Several unique cytogenetic features were observed. Twelve patie...

Among 17786 karyotyres performed in our center,during 18 years (1357-1375),1300(7.3%) cases of chromosome 21 aberration,including 1284(98.77%) of Down syndrome have been detected.1191 of cases (92.76%) born free trisomy 21:61 cases (4.75%) revealed translocation and 32 cases (2.4%) showed mosaic pattern.among the pateints,59 had robertsonian translocation,2 had translocation between chromosome ...

Triploidy is a lethal chromosomal abnormality. Foetuses with triploid condition have a tendency to die in early conception and very few survive to term. In this study, we report the prenatal diagnosis of fetal triploidy with unexpected chromosomal translocation. A 27 years old women was referred to our clinical cytogenetic department due to history of previous conceptus with intrauterine growth...
