Senior Director, Cytogenetics Laboratory
Dr. DuPont came to the GGC in 1999 as Director of the Cytogenetics Laboratory. This laboratory currently conducts over 4,000 clinical tests and 1,000 research tests per year and has 16 technologists. Her major areas of research interest include subtelomere rearrangements, phenotype/genotype mapping of chromosome rearrangements and deletion syndromes, the mechanisms of chromosome rearrangements, as well as, chromosome alterations in cancer. Her laboratory is currently working on studying the telomeres of a large population of South Carolina patients with intellectual disability of unknown etiology and dysmorphic features. She is also working in collaboration with Dr. Anand Srivastava and Dr. Charles Schwartz on genotype/phenotype mapping of patients with apparently balanced chromosome rearrangements.
Dr. DuPont is board certified by the American Board of Medical Genetics (1996) in clinical cytogenetics. She is a member of the American Society of Human Genetics, and a fellow of the American College of Medical Genetics. She is also a reviewer for a number of scientific journals including American Journal of Medical Genetics and Cytogenetics and Cell Genetics.
