Brief Summary
The purpose of this study is to identify genes that increase the risk of developing vasculitis, a group of severe diseases that feature inflammation of blood vessels. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.

Eligibility Criteria
Individuals with giant cell arteritis, Takayasu's arteritis, polyarteritis nodosa, granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis (Churg-Strauss). Enrollment will be sequential and patients will have disease in various stages and of different duration.
You may qualify if:
- \. Diagnostic criteria for Giant Cell Arteritis Age at disease onset \>50 years (required)
- New onset or new type of localized pain in the head
- Temporal artery abnormality (i.e. temporal artery tenderness to palpation or decreased pulsation, unrelated to arteriosclerosis of cervical arteries)
- ESR of \>40mm in the first hour by the Westergren method
- Abnormal artery biopsy (i.e. temporal artery biopsy showing vasculitis characterized by a predominance of mononuclear cell infiltration or granulomatous inflammation, usually with multinucleated giant cells)
- Large Vessel Vasculitis (LVV) by angiogram or biopsy not explained by something else
- \. Diagnostic criteria for Takayasu's Arteritis
- Age at disease onset \<50 years
- Claudication of extremities
- Decreased brachial artery pulse (one or both arteries)
- Blood pressure difference of \>10mm Hg between the arms
- Bruit over subclavian arteries or aorta
- Arteriogram abnormalities compatible with TAK (includes conventional dye angiography or MR angiography or CT angiography)
- \. Diagnostic criteria for Polyarteritis Nodosa Major criteria (not explained by other causes) felt by investigator to be due to vasculitis
- Arteriographic abnormality
- +32 more criteria
You may not qualify if:
- Inability to give informed consent and to sign the consent form
- Enrolled in VCRC protocols 5502, 5503, 5504, 5505, 5506, 5522, or 5523
- Unwilling to provide blood for DNA collection
