Human chromosome 19p: A fluorescence in situ hybridization map with genomic distance estimates for 79 intervals spanning 20 Mb
- Lawrence Livermore National Lab., CA (United States)
A physical map of human chromosome 19p has been constructed by fluorescence in situ hybridization of cosmids to metaphase chromosomes and sperm pronuclear interphases. The map spans {approximately}20 Mb and was generated with 141 multiple, partially overlapping estimates of genomic distances for 79 intervals separating 80 sequentially ordered cosmid reference points. The average distance separating pairs of cosmids was 250 kb, with a range from 50 to 700 kb; 75% of the intervals were estimated to be less than or equal to 300 kb and only 8 intervals were between 500 and 700 kb. Cosmids positive for 33 genes or gene families and 5 polymorphic markers were included among the mapped elements. The fluorescence in situ hybridization map will be useful for furthering the integration of the physical and genetic maps of 19p and for placing newly identified markers within a few hundred kb of their neighbors. 42 refs., 3 figs.
