MATR Repository

About the Repository

Studies involving twins are exceptional ways to learn about the genetic and environmental factors impacting our health. With a desire to maximize the capacity to learn from twins, Dr. Francis Macrina, VCU’s Vice President for Research, had a vision of a DNA repository which MATR in which MATR twins could participate. Through collaborations here at VCU, the vision of such a resource is now a reality.

The MATR DNA repository is a tremendous scientific resource which will allow researchers to take twin studies to a new level of scientific knowledge. Not only will researchers be able to collect useful information from twins, they can now utilize the twins’ DNA to truly realize the potential of studying genetic and environmental factors impacting our physical and mental health.

We are excited to be a part of the development of such a resource and look forward to watching it continue to grow.
