Previous studies have revealed that that approximately 10% to 15% of multiple myelomas (MMs) are characterized by a reciprocal t(4;14)(p16;q32) translocation that activates expression of FGFR3 and creates an IGH/MMSET fusion transcript. Current data suggest that activation of FGFR3 is the oncogenic consequence of this rearrangement. Using a combination of microarray profiling, reverse transcrip...
CD5(+) diffuse large B-cell lymphomas (DLBLs) have recently been described as a particular subgroup of DLBLs. Classical banding and interphase cytogenetic analyses targeting ATM, TP53, and P16(INK4a) genes and the D13S25 locus from 13 CD5(+) DLBLs were compared with 55 CD5(-) DLBLs. Additionally, analysis of somatic mutations of the immunoglobulin heavy chain variable region (IgVH) genes were p...
Double-hit lymphomas (DHL) are defined as B-cell lymphoma with a chromosomal breakpoint affecting the MYC/8q24 locus in combination with rearrangement at (14;18)(q32;q21). We recently observed three cases of B-cell lymphoma with an extra intact MYC signal in association with the t(14;18)(q32;q21) translocation. The impact of an extra copy of MYC to the clinical course and prognosis of one patie...
Background. We hereby describe what we believe to be the first reported case of t (14; 15) (q32; q13) associated with acute myeloid leukemia (AML). Methods. PubMed, Embase, and OVID search engines were used to review the related literature and similar published cases. Case. A47-year-old female presented in December 2011 with AML (acute myelomonocytic leukemia) with normal cytogenetics; molecula...
Here, we report a rare case of double-hit lymphoma, demonstrating t(6;14;18)(p25;q32;q21), suggesting two independent dual-translocations, c-MYC/BCL-2 and IRF4/BCL-2. The present case had a rare abnormal chromosome, t(6;14;18)(p25;q32;q21), independently, in addition to known dual-hit chromosomal abnormalities, t(14;18)(q32;q21) and t(8;22)(q24;q11.2). Lymph node was characterized by a follicul...
Translocation t(9;14)(p13;q32) involving PAX5 and IGH genes was first described in lymphoplasmacytic lymphoma. However, Tracy et al. recently studied a series of 37 low-grade B-cell lymphomas: 13 lymphoplasmacytic lymphomas, 18 marginal zone lymphomas (8 with the splenic form) and 6 small lymphocytic lymphomas by fluorescence in situ hybridization (FISH) with a PAX5 probe and did not detect any...
Hemophores from Serratia marcescens (HasA(sm)) and Pseudomonas aeruginosa (HasA(p)) bind hemin between two loops, which harbor the axial ligands H32 and Y75. Hemin binding to the Y75 loop triggers closing of the H32 loop and enables binding of H32. Because Yersinia pestis HasA (HasA(yp)) presents a Gln at position 32, we determined the structures of apo- and holo-HasA(yp). Surprisingly, the Q32...
Although many recurring chromosome abnormalities have been found in malignant lymphoma (ML) in recent years, their relationship to histology remains largely undefined. We have correlated, in the same tumor mass, chromosome findings with histology, defined by the International Working Formulation for Clinical Usage, in 120 patients. We find differences among histologies in the frequency of norma...
We have detected and cloned two rearrangements in the T-cell receptor alpha locus from a clone of somatic cell hybrids carrying a t(14;14)(q11;q32) chromosomal translocation derived from an ataxia telangiectasia patient with T-cell chronic lymphocytic leukemia. The T-cell clone carrying the t(14;14) chromosomal translocation was known to be present for greater than 10 years before the onset of ...
