Synopsis

There have been many advances in clinical cytogenetics since the first edition of this book appeared in 1989. The authors have written more expansively on segregation and risks in reciprocal translocations, X-autosome translocations, inversions, insertions, and prenatal diagnosis. The deletion syndromes have become more numerous, and more precisely defined, and this required treatment. Fluorescence in situ hybridization has become a routinely applied methodology, and its use has extended the power, and increased the sophistication, of the discipline of clinical cytogenetics. The Human Genome Project is unravelling the complexity of our genetic inheritance, and readers will find evidence of its impact on the practicalities of human cytogenetics throughout the book. Two phrases not used at all in the first edition are dynamic mutation and genomic imprinting. The fragile X syndrome now has the status of the prototypical dynamic mutation. The authors completely rewrote this chapter, giving it a much more molecular character. The Prader-Willi and Angelman syndromes, likewise, have become the classic examples of genomic imprinting and uniparental disomy.

Présentation de l'éditeur

Chromosomal abnormalities can cause disability in children, and reproductive difficulty in parents. Many parents and couples seek genetic counselling in order to learn why they, or a relative, may have had a child with a particular collection of medical problems and/or intellectual disability. There may have been a history of multiple miscarriage, or infertility. They may want to know the outlook for a pregnancy, and what the risks might be. These and other questions concerning chromosome abnormalities are addressed in this standard text, which will be of interest to genetic counsellors, medical geneticists, paediatricians and obstetricians, infertility specialists, and laboratory cytogeneticists. This third edition has been thoroughly updated, and is richly illustrated and fully referenced. New chapters have been written on preimplantation diagnosis and recent advances in molecular cytogenetics are noted. The book will give counsellors the information that will enable them to help concerned parents accommodate to their particular "chromosomal situation", and to determine what may be, for them, the best course of action.
