Michigan State University Twin Registry (MSUTR)
MSUTR is a population-based twin registry based at Michigan State University (MSU) in the United States. It was created to examine developmental differences in genetic, environmental, and neurobiological influences on internalising and externalising symptoms. The registry began in 2001 as a university-based registry assessing undergraduates enrolled at MSU and expanded in 2004 to include twins aged 3 to 55. As of 2024, it includes thousands of twins and their families from Michigan and surrounding states. Since 2008, most participants have been recruited through the Michigan Twins Project (MTP); a brief mail-in survey which serves as an introduction to the registry and is now the most common way for twins to get involved with the MSUTR.
