This classic text covers over 700 different genetic syndromes affecting body structures, and has established itself as the definitive, comprehensive work on the subject. The discussion covers the phenotype spectrum, epidemiology, mode of inheritance, pathogenesis, and clinical profile of each condition, all of which is accompanied by a wealth of illustrations. The authors are recognized leaders in the field, and their vast knowledge and strong clinical judgment will help readers make sense of this complex and burgeoning field. New syndromes have been added to this edition and existing syndromes have been updated. This book will appeal to clinical geneticists, pediatricians, neurologists, head and neck surgeons, otolaryngologists, and dentists. "I have to agree with Dr. John Opitz, who in the foreword to the fourth edition (2001), noted: "'Gorlin's Syndromes of the Head and Neck' is known throughout the world, it has become the most useful book in clinical genetics, rivaled perhaps only by McKusick's OMIM." This book is an indispensable tool for modern dysmorphologists and is based on the vision and wonderful mind of Bob Gorlin. Congratulations to the editors of this edition for a job well done." -- Doody's The definitive work on the subject! Raoul C. M.
