"The new edition of this book addresses the range of advances in the study of genetically caused abnormalities of human development. This edition features a wealth of color illustrations. The operating principle for organizing the clinical chapters remains one that is based on the notion of developmental pathways, analogous to the biochemical pathways that are involved in the inborn errors of metabolism." "This book will be a resource for physicians, dentists, genetic counselors, and other health professionals interested in going beyond clinical descriptions of multiple malformation syndromes to gain an understanding of their genetic basis and pathogenesis. It is also intended for the increasing number of basic scientists and students interested in developmental processes and in the human disorders that result from genetic perturbations that affect them."--BOOK JACKET.
