RT Journal A1 TOWNES PL T1 CLinical atlas of human chromosomes JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1979 FD February 1 VO 133 IS 2 SP 226 OP 226 DO 10.1001/archpedi.1979.02130020118034 UL http://dx.doi.org/10.1001/archpedi.1979.02130020118034 AB The basic organization of the Atlas is sequential, with a section or chapter devoted to each chromosome starting with chromosome 1 and continuing numerically to chromosome 22 and the sex chromosomes. All sections have identical headings and subheadings, which greatly facilitates rapid reference and use of the Atlas. Each section is prefaced by brief summary statements concerning the status of the chromosome in primate evolution, the number of recognized gene loci, and the clinical importance of the specific chromosome. These statements are followed by a brief introductory paragraph and a section on "Morphology and Banding" that contains a series of photographs of the specific chromosome with conventional, quinacrine fluorescence, trypsin-Giemsa G, Giemsa R, acridine orange R, and T and C banding that are all horizontally aligned with a schematic diagram of banding according to the Paris conference. A similar diagram showing the recognized gene loci of the specific chromosome is
