Blood samples and health information (e.g., age at diagnosis, test results) are collected for the purposes of genetic research. The blood samples are assigned a number and stored in a repository for safe keeping until they are needed for a research project. Participants are persons who are healthy (not having high blood pressure, diabetes, or high cholesterol levels) or persons who have Diabetes Mellitus Type II(T2D) and live in Indiana. Participants complete a questionnaire at the time the blood sample is drawn. Visits are repeated at 2 and 5 years after initial contact. Researchers apply to the Fairbanks Institute for use of the blood samples and health information minus participant names and contact information. Their research is required to be related to find genes or substances made by genes that may be involved in Diabetes Mellitus Type II with the purpose of improving the investigators understanding of the illness potentially leading to the development of new diagnostic tools for identifying the illness, new treatments,or preventative measures.
