The recurrent translocation t(11;16)(q23;p13) has been reported to be associated with therapy-related acute leukemia. The MLL gene involved in other 11q23 abnormalities was also rearranged by this translocation. We analyzed two patients with myelodysplastic syndrome with t(11;16) and showed that the MLL gene on 11q23 was fused with CREB-binding protein (CBP) gene on 16p13 in these patients. The...

Fusion genes implicating the MLL gene have been recently demonstrated in various 11q23 chromosomal abnormalities in human hematopoietic malignancies. We analyzed a t(6;11)(q21;q23) translocation detected in a secondary acute myeloblastic leukemia. This translocation results in fusion of the MLL gene on 11q23 to a previously unknown gene on chromosome 6 that differs from the previously reported ...

The breakpoint of t(11;14)(q23;q32) chromosome translocation in a B-cell lymphoma line, RC-K8, was cloned. Immunoglobulin heavy chain (IGH) constant gene, C gamma 2 at the 5' end, was involved in this translocation, and the DNA segment juxtaposed to the C gamma 2 was proved to be derived from chromosome 11 by somatic cell hybrid study. The normal counterpart of chromosome 11 was also isolated. ...

The MLL gene, on human chromosome 11q23, undergoes chromosomal translocation in acute leukemias, resulting in gene fusion with AF4 (chromosome 4) and ENL (chromosome 19). We report here translocation of MLL with nine different chromosomes and two paracentric chromosome 11 deletions in early B cell, B- or T-cell lineage, or nonlymphocytic acute leukemias. The mRNA translocation junction from 22 ...

BACKGROUND AND OBJECTIVES In acute leukemias, chromosomal translocations involving the 11q23 band are frequently, but not invariably, associated with MLL gene rearrangement and their finding is associated with a poor prognosis. We observed two new translocations with a breakpoint in the 11q23 region at standard cytogenetic analysis: a previously undescribed t(3;11)(q21;q23) in a 70-year old wom...

A newborn male infant with multiple congenital abnormalities was found to be trisomic for 3p23----pter and monosomic for 11q23----qter. His parents were both carriers of a balanced reciprocal translocation. Considerable overlap in phenotype-karyotype correlations was found between the two chromosomal syndromes in the patient.

The constitutional t(11;22) is the most frequently occurring non-Robertsonian translocation in humans. The breakpoint (BP) of the t(11;22) has been identified within palindromic AT-rich repeats (PATRRs) on chromosomes 11 and 22, suggesting that hairpin/cruciform structures mediate double-strand breaks leading to the translocation. To further characterize the mechanism of the translocation, iden...

The constitutional t(11;22) is the most frequent recurrent non-Robertsonian translocation in humans, the breakpoints of which are located within palindromic AT-rich repeats on 11q23 and 22q11 (PATRR11 and PATRR22). Genetic variation of the PATRR11 was found to affect de novo t(11;22) translocation frequency in sperm derived from normal healthy males, suggesting the hypothesis that polymorphisms...

The MLL gene involved in 11q23 translocations found in the majority of infantile leukemias and some secondary leukemias makes fusion transcripts with genes such as LTG4 (chromosome 4), LTG9 (chromosome 9), and LTG19 (chromosome 19) as a result of reciprocal translocation. We have examined 25 cases of leukemias with 11q23 abnormalities by Southern blot analysis and the reverse transcriptase-poly...

Translocations involving the HRX/ALL1 locus at chromosomal region 11q23 are among the most frequent cytogenetic abnormalities in acute leukemias. 11q23 translocations involve different chromosome partners and lead to the formation of HRX/ALL1 fusion proteins. The HRX/ALL1 protein is a putative transcription factor that has been implicated in developmental regulation in mammals. We report here t...
