David H. Ledbetter, Ph.D.

David H. Ledbetter, Ph.D., discovered the microdeletion in chromosome
15 as the major cause of Prader-Willi syndrome while a graduate student, which launched a life-long research interest in the mechanism and consequences of this and similar chromosome abnormalities. His broader interest in the genetic basis of developmental disabilities in children led to the development of a complete set of human telomere clones, now used routinely in the evaluation of all children with unexplained developmental delay or mental retardation using "telomere FISH" test. He is currently the Robert W. Woodruff Professor of Human Genetics at Emory University School of Medicine.
