Roger Stevenson 12Although considerable progress has been made in recent decades, the understanding of birth defects and intellectual disabilities is surprisingly limited. In only about half of patients who have intellectual disabilities or significant birth defects can the cause be identified - a necessary first step if prevention strategies are to be developed.

Dr. Stevenson’s professional career has been devoted to the study of birth defects and developmental impairments. He has contributed broadly to the literature on the cytogenetic, metabolic, molecular and environmental causes of these disabilities, authored two editions of the textbook The Fetus and Newly Born Infant, Influences of the Prenatal Environment, and with Dr. Judith Hall produced two editions of Human Malformations and Related Anomalies. He and his colleagues, Charles Schwartz, PhD and Curtis Rogers, MD, authored Atlas of X-Linked Intellectual Disability Syndromes (Oxford University Press, 2012).
