Protocol Number: 05-I-0213
Patients of any age with abnormal immune function who have recurrent or unusual infections, whose blood tests show evidence of immune dysfunction, or who have GVHD, XSCID, CGD or LAD may be eligible for this study. Patients' parents, siblings, grandparents, children, aunts, uncles and first cousins of any age also may be included. Healthy normal volunteers between 18 and 85 years of age are recruited as controls. Normal volunteers undergo a physical examination and provide blood, saliva, and urine samples for immune function studies. Patients' family members provide a medical history, have a physical examination, and give blood and urine samples, and possibly a saliva sample. The samples are used for genetic and routine laboratory studies. Investigators may request tissue samples, such as biopsy specimens, previously removed for medical reasons to be sent to NIH for study. Patients undergo the following tests and procedures: 1. Medical history and physical examination. 2. Blood and urine tests, including analysis for genes involved in immune disorders. 3. Buccal smear (in some patients) for genetic studies. This involves scraping the lining of the mouth near the cheek. 4. Specialized tests to evaluate specific conditions in patients who have an immune disorder that might affect lung function, gum infections or eye problems. These may include chest x-ray, CT scan, breathing function test, dental, eye, and hearing examinations. 5. Follow-up visits of patients with immune problems may occur at 6 months and at one year after the first visit (or more frequently if medically required) to include: -Medical history update -Physical examination -Follow-up on abnormal test results and medical treatments initiated at NIH -Collection of blood, saliva, urine, or wound drainage samples for repeat immune function studies -Tissue study of specimens removed for medical reasons at other institutions besides NIH
