Genetic Mutation in Amish Linked to Longer Life
November 16, 2017
A genetic mutation in an Amish community in Indiana that can cause fatal blood clotting has been linked to longevity and protection against diabetes, according to a study published in Science Advances this week (November 15).
Previous research has shown that the gene in question, SERPINE1, produces a protein that can promote aging in mice. Levels of the protein, called plasminogen activator inhibitor type 1 (PAI-1), are higher in patients with diabetes, obesity, or cardiovascular disease. PAI-1 is also known to play an important role in blood clotting, and people with two defect copies of SERPINE1 suffer from blood clotting disorders, Science reported.
