Title:

Stroke Genomics - A Correlative Study of Stroke Subtypes, Neuroimaging, Therapy and Outcome Measures

Number:

02-N-0221

Summary:

This study will characterize the gene response of the body's immune and inflammatory cells to stroke. There is a wide variation in stroke risk, stroke outcome, and response to clot-busting therapy for stroke. This variation may be due to differences in people's response to injury or infection, or to differences in genetic make-up between individuals. Genes store the biological information that determines the body's response to injury or infection. This study will analyze the activity of a large number of genes to try to learn which genes might be related to patient outcome. This, in turn, may lead to an understanding of which gene profiles are related to increased stroke risk and increased disability or death.

Healthy volunteers over age 21 and stroke patients over age 21 who are admitted to the NIH Stroke Program at Suburban Hospital in Bethesda, Md., may be eligible for this study. Volunteers will be screened with a medical history, blood pressure and pulse measurements, electrocardiogram, and neurological examination.

Participants will have 20 to 35 milliliters (about an ounce) of blood drawn for genetic studies. The genetic material will be extracted from the white blood cells and analyzed for normal and abnormal gene activity related to stroke.
