A chromosome 21-specific cosmid cocktail for the detection of chromosome 21 aberrations in interphase nuclei.
Fluorescent in situ hybridization (FISH) with a 21q11-specific probe (CB21c1) consisting of three non-overlapping cosmids has been applied to interphase amniocytes of pregnancies at increased risk for fetal aneuploidy (N = 78) and to interphase lymphocytes, cultured and uncultured, of patients referred for Down syndrome (N = 19 and 28, respectively). In the uncultured amniocytes, six chromosome...

متن کاملChromosome-21 and Paroxysmal Nocturnal Hemoglobinuria.
LTHOUGH great strides have been made in the past decade in both cytogenetics and biochemical genetics, the location of genes on the 44 autosomes has remained unknown. The experiments of nature in which an additional chromosome-21 is present and where a portion of this chromosome has been deleted have provided, for the first time, a clue to the possible location of some autosomal genes. The stud...
متن کاملTrisomy of chromosome 21 in leukemogenesis.
Extra copies of chromosome 21 are often found in sporadic leukemias. Constitutional trisomy 21 of Down syndrome (DS) is associated with markedly increased risk for childhood leukemia. Thus the oncogenic role of trisomy 21 in the more common sporadic childhood leukemias may be revealed through the investigations of the relatively rare leukemias of DS. Recent studies of the megakaryoblastic leuke...
متن کاملEvolutionarily conserved sequences on human chromosome 21.
Comparison of human sequences with the DNA of other mammals is an excellent means of identifying functional elements in the human genome. Here we describe the utility of high-density oligonucleotide arrays as a rapid approach for comparing human sequences with the DNA of multiple species whose sequences are not presently available. High-density arrays representing approximately 22.5 Mb of nonre...
