Mid-Atlantic Twin Registry

The Mid-Atlantic Twin Registry (MATR) is an organization of twins and their families who are willing to consider taking part in twin-based, health-related research. The MATR welcomes twins of any age, ethnicity, and zygosity (identical or fraternal), as well as higher order multiples such as triplets, quadruplets and quintuplets. Most of the twins registered in the MATR are from Virginia, North Carolina, and South Carolina, but twins from all over the country and all around the world are welcome to register with us!

MATR Repository: The MATR also houses a repository containing DNA samples provided by more than one-thousand twins. This repository is a tremendous scientific resource which allows researchers to study the twins’ data collected by studies along with their DNA.

MATR Mission Statement: The mission of the Mid-Atlantic Twin Registry (MATR) is to promote the mental and physical well-being of all men, women, and children through the support of major health research on twins and their family members. Our goal is to serve as a model for the protection and privacy of participants in human research and as a leader in twin registry-based research.
