INTRODUCTION Array comparative genomic hybridisation (array CGH) is a powerful method that detects alteration of gene copy number with greater resolution and efficiency than traditional methods. However, its ability to detect disease causing duplications in constitutional genomic DNA has not been shown. We developed an array CGH assay for X linked hypopituitarism, which is associated with dupli...
We studied the genomic status of BCL6 in 23 cases of nodular lymphocyte predominance Hodgkin lymphoma (NLPHL) and 40 cases of classical Hodgkin lymphoma (cHL), using dual-color interphase fluorescence in situ hybridization (FISH). The BCL6 rearrangement was identified in 48% of NLPHL cases and was not detected in cHL cases. As a confirmation, sequential or simultaneous immunohistochemistry (IHC...
The fragile X syndrome is a common X-linked mental retardation and autism, affecting females as well as males. The fragile site X chromosomes were studied in a series of 153 mentally retarded boys of unknown etiology to determine the frequency of fragile X syndrome, and to assess the feasibility of making a clinical diagnosis of the fragile X syndrome in young boys before cytogenetic results we...
We report a series of 20 non-Hodgkin's lymphomas (NHL) in which cytogenetic analysis showed a translocation involving band 3q27 and the site of one of the three Ig genes (14q32, 2p12, 22q11) in the neoplastic cells. These cases were found in a series of 319 patients with clonal chromosomal abnormalities studied over a 7-year period. Fourteen patients had diffuse lymphoma, mainly of large cell t...
Although it is known that parental carriers of structural chromosomal rearrangements are associated with recurrent pregnancy loss, subsequent natural pregnancies remain possible. We examined the reproductive outcome of a familial balanced translocation with t(3;6)(q12;q27). Karyotyping of the proband revealed 46,XY chromosomes with the balanced translocation t(3;6). The first 2 pregnancies resu...
