National Institute of Allergy and Infectious Diseases (NIAID)
Background: * National Institutes of Health (NIH) researchers have been studying immune cells (white blood cells) to better understand how the human body s defense system works and adjusts or regulates itself, and how changes in this system can make a person sick. * To study the cells of patients who have problems with their immune systems, researchers would like to collect samples of skin cells from patients with immune system disorders and compare them with skin cells taken from healthy volunteers. By studying these cells, researchers hope to determine whether these cells can be modified to create a new kind of personalized gene therapy that would attempt to cure immune diseases in the future. Objectives: * To obtain skin cells from patients with immune system disorders and from healthy volunteers for research and comparison purposes. Eligibility: * Patients between the ages of 2 and 85 who have immune system disorders. * Healthy volunteers between the ages of 18 and 85. * Both groups will be selected from the eligible participants of existing NIH studies into immune system disorders. Design: * Researchers may take up to two biopsies from participants arms, legs, abdomen, or back. * The biopsy site will be numbed with local anesthetic and cleaned before the sample is taken. * The punch skin biopsy needle will be inserted into the skin and rotated to remove a small circle of skin (approximately 1/4 to 3/8 of an inch across). The area will be closed with bandages or stitches, and then covered with a dressing. Any stitches will be removed in 7 to 10 days. * Tissue samples collected in the study will be stored for future research.
This protocol is designed as an adjunct to other National Institutes of Health (NIH) IRB approved protocols that allow for genetic testing, which may include those that are screening protocols for patients with rare primary immunodeficiency or immunodysregulation disorders. Patients deemed of sufficient research interest after review of outside medical records, clinical evaluation, and testing, may be invited to participate in this study. Healthy volunteers and relatives of patients will also be invited to participate as a source of control samples for research testing. After consent and enrol…
* INCLUSION CRITERIA: Patients: 1. To be enrolled in this study, a patient must be \>=2 years of age but not \>85 years of age, 2. have a known diagnosis of primary immunodeficiency or immunodysregulation (or be a blood relative of such as patient), 3. be concurrently enrolled on an NIH IRB approved NIAID protocol that includes genetic testing for disease of the immune system, such as but not limited to 05-I-0213 or 06-I-0015 Patient Relative: To be enrolled in this study, a patient relative must be: 1. A biological relative of a participant being studied under this protocol. Relatives may…
