| Study Name | Who Can Participate? | | SEARCH for Diabetes in Youth (SEARCH) | Children and youth who are under age 20 when they were diagnosed with diabetes may be eligible to join. Eligibility may depend on the place the child or young adult resides or the place where health care is received.
| | Type 1 Diabetes Genetics Consortium (T1DGC) | The T1DGC has completed enrollment for the affected sibling pair families phase of the study. We would like to thank all of participants worldwide who helped the study reach this monumental goal.
We are continuing to recruit trios (father, mother, and a child with type 1 diabetes), as well as cases (with type 1 diabetes) and controls (no history of type 1 diabetes) from populations with a low prevalence of the disease only as we have adequate numbers of Caucasians of European origins. In Asia Pacific, this includes individuals from countries such as India and Thailand. In North America, this includes Mexican American and African American individuals.
| | Family Investigation of Nephropathy and Diabetes (FIND) | In order for a family to participate, there must be at least one person with kidney disease due to diabetes. In addition, there must be at least one full brother/sister (not a half or step brother/sister) who: (1) has diabetes and kidney disease OR (2) has had diabetes for more than 10 years and does not have kidney disease. A family with a member with diabetic kidney disease whose two parents are willing to participate may also be enrolled in the study. Other family members may be recruited to the study as well.
There are also opportunities for Mexican-American patients with diabetic kidney disease, and African-American patients with diabetic and non-diabetic kidney disease and their families to participate as well.
| | TrialNet-MMF/DZB (TrialNet) | This study is no longer recruiting patients. Persons who had developed type 1 (insulin dependent) diabetes within the last three months and who are between the ages of 12 and 35 were eligible to participate.
