Inborn Errors of Development is the definitive work on genetically caused abnormailities of human development. Despite the explosion in genetic advances, the causes of two-thirds of all birth defects remain unknown. However, we are on the brink of a revolution in this area, and this book is at the forefront. It is the first book to connect the disease-causing gene to its biochemical pathway and to the structural/functional disorder. Mutations of the gene, the clinical picture, genetic counselling and prognosis, and any known treatments are discussed.
