The simultaneous and unequivocal discernment of all human chromosomes in different colors would be of significant clinical and biologic importance. Whole-genome scanning by spectral karyotyping allowed instantaneous visualization of defined emission spectra for each human chromosome after fluorescence in situ hybridization. By means of computer separation(More)
Murine models of human carcinogenesis are exceedingly valuable tools to understand genetic mechanisms of neoplastic growth. The identification of recurrent chromosomal rearrangements by cytogenetic techniques serves as an initial screening test for tumour specific aberrations. In murine models of human carcinogenesis, however, karyotype analysis is(More)
A number of unique sequence recombinant DNA clones were isolated from a recombinant DNA library constructed from DNA enriched for chromosome 21 by flow sorting. Of these, five were mapped to chromosome 21 using a somatic cell hybrid. Regional mapping of these probes and of a probe previously assigned to chromosome 21, was carried out with the aid of(More)
A novel polymerase chain reaction (PCR) technique has been combined with chromosome flow sorting to characterise two lymphoblastoid cell lines and one medullary thyroid carcinoma cell line carrying translocations close to the locus for multiple endocrine neoplasia type 2A (MEN 2A). Five hundred copies of the derivative chromosome(s) were flow sorted from(More)
Human centromeres have been extensively studied over the past two decades. Consequently, more is known of centromere structure and organization in humans than in any other higher eukaryote species. Recent advances in the construction of a human (or mammalian) artificial chromosome have fostered increased interest in determining the structure and function of(More)
Chicken genome mapping is important for a range of scientific disciplines. The ability to distinguish chromosomes of the chicken and other birds is thus a priority. Here we describe the molecular cytogenetic characterization of each chicken chromosome using chromosome painting and mapping of individual clones by FISH. Where possible, we have assigned the(More)
Mendelian inherited disorders due to deletions of adjacent genes on a chromosome have been described as "contiguous gene syndromes." Short stature, chondrodysplasia punctata, mental retardation, steroid sulfatase deficiency, and Kallmann syndrome have been found as isolated entities or associated in various combinations in 27 patients with interstitial and(More)
Von Hippel-Lindau (VHL) disease is a dominantly inherited familial cancer syndrome predisposing to a variety of malignant and benign neoplasms, most frequently retinal, cerebellar and spinal haemangioblastoma, renal cell carcinoma, phaeochromocytoma and pancreatic tumours. We have previously detected large germline deletions by Southern analysis and pulsed(More)
