We have generated a panel of 55 somatic cell hybrids retaining fragments of human chromosome 4. Each hybrid has been characterized cytogenetically by FISH and molecularly by 37 STSs, evenly spaced along the chromosome. The panel can be exploited to map subregionally DNA sequences on chromosome 4 and to generate partial chromosome paints useful in the(More)
A patient with a typical form of chronic myeloid leukemia was found to carry a large deletion on the derivative chromosome 9q+ and an unusual BCR-ABL transcript characterized by the insertion, between BCR exon 14 and ABL exon 2, of 126 bp derived from a region located on chromosome 9, 1.4 Mb 5' to ABL. This sequence was contained in the bacterial artificial(More)
Low-grade fibromyxoid sarcoma (LGFMS) is a variant of fibrosarcoma that was recognized as a distinct tumor entity only quite recently. We previously described a translocation, t(7;16)(q33;p11), that resulted in a fusion of the FUS and CREB3L2 (also known as BBF2H7) genes in two soft tissue tumors that fulfilled morphologic criteria for LGFMS. To delineate(More)
The 22q11.2 microdeletion syndrome is the most frequent microdeletion syndrome in humans, yet its genetic basis is complex and is still not fully understood. Most patients harbor a 3-Mb deletion (typically deleted region [TDR]), but occasionally patients with atypical deletions, some of which do not overlap with each other and/or the TDR, have been(More)
Previous studies have suggested that amplification of genes, notably the TOP2A gene, on chromosome arm 17q may be important for the development of malignant peripheral nerve sheath tumour (MPNST). In order to study the frequency, distribution, and chromosomal organization of rearrangements at 17q, interphase and metaphase fluorescence in situ hybridization(More)
The screening of a human genomic library with a chemokine receptor-like probe allowed us to obtain a putative member of the G protein-coupled receptor gene (GPCR) family, designated GPR31. Its deduced amino acid sequence encodes a polypeptide of 319 amino acids that shares 25-33% homology with members of the chemokine, purino, and somatostatin receptor gene(More)
The "golden path", produced by the Human Genome Project effort, is composed of a collection of overlapping and fully sequenced BAC/PAC clones covering almost completely the human genome. These clones can be advantageously exploited as fluorescence in situ hybridization (FISH) probes for the characterization of rearrangements frequently found in tumors.(More)
BACKGROUND Deletions of IKAROS (IKZF1) frequently occur in B-cell precursor acute lymphoblastic leukemia (B-ALL) but the mechanisms by which they influence pathogenesis are unclear. To address this issue, a cohort of 144 adult B-ALL patients (106 BCR-ABL1-positive and 38 B-ALL negative for known molecular rearrangements) was screened for IKZF1 deletions by(More)
The FUS gene at 16p11 fuses with DDIT3 and ATF1 as the result of translocations with chromosome band 12q13 in myxoid liposarcoma and angiomatoid fibrous histiocytoma, respectively, and with ERG as the result of a t(16;21)(p11;q22) in acute myeloid leukemia. We here show that a t(7;16)(q33;p11) in two cases of low grade fibromyxoid sarcoma fuses the FUS gene(More)
We report on a boy with three cell lines: 46,XY, r(11)(p15.5,q25)[90]/45,XY,-11 [8]/47,XY, r(11)(p15.5,q25)x2[2], with minor anomalies and mental retardation who developed asynchronous bilateral Wilms tumors (WTs). Array comparative genomic hybridization (CGH) performed on peripheral blood leukocytes of the patient led to the identification of a(More)
