Bringing together top-level contributions on all aspects of the subject, this book provides an overview of the recent advances in the genetics of respiratory control in health and disease. It also shows how combined studies in humans and mouse models have helped to improve our understanding of the mechanisms that underlie genetically determined respiratory control disorders with the goal of developing new therapeutic interventions.
