With the advent of the new banding techniques in human cytogenetics, it has become possible to detect small changes in the human karyotype that can be related to specific phenotypic manifestations. These new syndromes have been described with increasing frequency in the literature, and the permutations of physical findings in clinical diagnosis have been increased accordingly. Fortunately, the spirit of Diderot and the French encyclopedists is not dead; Jean de Grouchy and Catherine Turleau have produced in Paris, in 1982, a magnificent atlas of chromosomal abnormalities. They describe, with the use of clinical notes, illustrations, and karyotypes, the principal cytogenetic syndromes, including the known partial trisomies, monosomies, ring chromosomes, polysomies, and polyploidies, to date.
In each section, the authors correlate cytogenetic data with the latest available assignments of loci on the gene map. As an example of the detail in this book, in the section on chromosome 1, three different
