Brief Summary:
The purposes of this study are to 1 identify the genes responsible for certain immune disorders 2 learn about the medical problems they cause and 3 learn how to predict who is likely to develop these disorders and what the risk is of passing them on to children The immune system is the body s defense system Some immune deficiencies impair a person s ability to fight infections others render a person susceptible to allergies or to autoimmune diseases such as lupus or arthritis in which the immune cells white blood cells attack and destroy the body s own tissues
Patients with immune disorders known or suspected to have a genetic basis and their family members may enroll in this study Eligibility will be determined by a review of the patient s medical records and family medical history Participants will provide a small blood sample for genetic DNA and white blood cell analysis Gene samples but not white blood cells may also be obtained by mouth brushing or skin biopsy For the mouth brushing a small brush is rubbed against the inside of the cheeks for 1 minute to wipe off some cells For the skin biopsy a small circle of skin about 18 inch is removed under local anesthetic Pregnant women may be asked to provide a fetal sample amniotic fluid cells or chorionic villus sample All samples will be used for immune or genetic studies of the family s immune disorder
If test results show a specific genetic variation responsible for the family s immune disorder a report will be sent to the patient s doctor or genetic counselor who will discuss the implications for the family NIH researchers and genetic counselors will also be available to explain results and answer questions Information will not be available in the case of disorders that cannot yet be linked to a specific genetic abnormality
Information from this study will increase knowledge about the immune system and what causes immune deficiencies Participants may also learn the underlying cause of an immune disorder that affects them or someone in their family information may be useful in guiding treatment and in making decisions regarding family planning

Detailed Description:
This protocol includes studies of genetic defects of the immune system that cause failure of host defenses against infections immune dysregulation and autoimmune diseases Numerous rare disorders result from inherited or newly arising mutations in genes involved in the development and function of innate and adaptive immune systems or both As specific disease syndromes are defined and the responsible genes identified mutations in individual families can be sought Correlation of mutation sites with clinical information helps to determine how specific gene segments encode important functional domains of the proteins of the immune system within the same genetic defect Rare single gene disorders identify immunologic pathways that might contribute to more common conditions such as failure to respond to vaccines susceptibility to allergies or autoimmune diseases like arthritis or lupus
Members of families with immune disorders that are known or suspected to have a genetic basis may be eligible Immunologic tests and DNA sequence analysis appropriate to each clinical condition will be performed as needed on affected individuals and at-risk family members Healthy family members may serve as controls Probands parents of deceased affected individuals or entire families may be referred to the Investigators Initially clinical and family history as well as laboratory data will be reviewed by the investigators to determine eligibility Subjects considered appropriate will be invited through their referring physician to participate by signing our consent form and sending appropriate blood DNA or other samples to our PI Should a genetic basis for an individual s immune disorder be identified or if clinical eligibility for other protocols is met they may be invited to visit NIH
