Not so long ago, many people believed that autism was caused by bad parenting, that social factors caused schizophrenia, and that obesity was due to a lack of will power. By studying twins, we now know that all three conditions are strongly influenced by genes. These examples show the value of twin studies in medical and behavioral health research. In fact, twin studies have provided invaluable insights into conditions as diverse as multiple sclerosis, cardiovascular disease, and type II diabetes. And twin studies hold great promise to continue to produce important discoveries in medicine and behavioral science.

At present, the UW Twin Registry is one of the largest twin registries in the United States with more than 8,000 twin pairs currently enrolled and as many as 100 new pairs added each month. The UW Twin Registry receives no direct support from government agencies but has successfully competed for multiple large Federal research grants, primarily from the National Institutes of Health, and from select private foundations.

Unfortunately, as valuable as the UW Twin Registry is, it is threatened by the uncertainty of Federal and private grant funding in the future. Thus, we are looking for ways to ensure the Registry’s long-term survival. Below are ways you can support our important work:
