Margaret Pericak-Vance
Margaret Ann Pericak-Vance is an American human geneticist who is the Dr. John T. Macdonald Foundation Professor of Human Genetics and director of the John P. Hussman Institute for Human Genomics at the University of Miami. She is known for her research on the genetics of common human diseases. This research has led to a number of findings of genes that increase the risk of certain diseases, such as apolipoprotein E and Alzheimer's disease, interleukin-7 receptor and multiple sclerosis, and complement factor H and macular degeneration.
Education and career
A native of Buffalo, New York, Pericak-Vance attended Wells College, graduating in 1973 with a bachelor's degree in biology. She went on to earn her Ph.D. in 1978 from Indiana University School of Medicine: Department of Medical and Molecular Genetics, where she studied under P. Michael Conneally. She did a post-doctoral fellowship at the University of North Carolina Chapel Hill under Robert C. Elston. She subsequently served on the faculty of Duke University, where she eventually became director of the Center for Human Genetics, James B. Duke Professor of Medicine, and Chief of the Section of Medical Genetics at Duke University Medical Center.In January 2007, Pericak-Vance left Duke to help launch the Miami Institute for Human Genomics, which is now the John P. Hussman Institute for Human Genomics at the University of Miami's Miller School of Medicine.
Scientific Contributions
Alzheimer's disease research
In 1993, Pericak-Vance and her colleagues identified the APOE-4 allele as a significant genetic risk factor for late-onset Alzheimer's disease. Their research demonstrated that individuals carrying this allele had an increased likelihood of developing the disease, making it the most significant genetic risk factor beyond age. Pericak-Vance and colleagues published a study in Science identifying the APOE-4 allele as a genetic risk factor for late-onset Alzheimer's disease, one of the first gene variants associated with a common neurological disorder. As of 2023, the study is the most-cited original research paper in Alzheimer's studies of the past 50 years.In 1994, Pericak-Vance and her team demonstrated that the APOE-e2 allele had a protective effect against Alzheimer's disease, the earliest example of different alleles of the same gene having differing effects on disease susceptibility. Subsequent research has cited these findings as influential in shaping approaches to studying genetic risk and protection in complex diseases.
In 2018, Pericak-Vance co-authored a study examining the APOE-ε4 allele in Puerto Rican and African American populations, which highlighted how ancestry can moderate genetic risk for Alzheimer's disease.
In 2025, Pericak-Vance and colleagues analyzed the relationship between telomere length and cognitive impairment in Midwestern Amish populations in the context of understanding the process of age-related neurodegeneration. The team determined that telomere length decreased during aging — an expected finding, but found no significant results between cognition and telomere length.
