I would like to express my sincere thanks to the many people who walked through the writing of this book with me. My partners, colleagues, and office were simply selfless in allowing me time off and away to write. My family and friends were so patient in listening to my angst as I often stalled in the process. I would particularly like to thank our accomplished group of medical reviewers. Their comments, insight and suggestions were invaluable:
University of Colorado (Denver) School of Medicine
Children's Hospitals and Clinics of Minnesota
Sonja A. Rasmussen, MD, MS
Centers for Disease Control and Prevention
I, too, owe a debt of gratitude to the reviewers who made many constructive recommendations to improve this book and to my family and friends who supported and encouraged me during the project. In addition, I thank the many students over the years who have asked questions that made me think about concepts in a new way and who encouraged my work through their individual successes. The changing face of a science like medical genetics leads us all to continue being students.
