The study will allow researchers to obtain blood, plasma, DNA, and RNA for genetic studies of insulin. There will be a focus on the causes of insulin resistance and diabetes mellitus. Insulin is a hormone found in the body that controls the level of sugar in the blood. Insulin resistance refers to conditions like diabetes when insulin does not work properly. In this study researchers would like to compare patients with diabetes and other forms of insulin resistance to normal individuals. The study will investigate how insulin attaches to cells. Researchers will take 4 to 6 ounces (100-150 ml) of blood from adult patients and may request up to 12 ounces (one unit) of blood if necessary. Skin samples may be taken for a biopsy if further genetic testing is necessary. In addition some patients may be asked not to eat for up to 72 hours prior to testing....
