Testing, testing, testees wanted!

I was perusing the intrawebs as I am known to do sometimes and I came across some interesting factoids on one of the vasculitis pages I frequently lurk.
There's a VCRC Genetic Repository study currently going on- they need something like 1300 participants from several different types of vasculitis: Churg-Strauss syndrome (CSS), giant cell arteritis (GCA), microscopic polyangiitis (MPA), polyarteritis nodosa (PAN), Takayasu's arteritis (TAK), and Wegener's granulomatosis (WG). They are looking for genetic materials from patients in the hopes that they can find some king of genetic link for these diseases. As of right now, there is no known cause for vasculitis.
Study Name: 5510 - VCRC Genetic Repository One-Time DNA Collection Protocol

• VCRC Genetic Repository - Recruiting

  The Vasculitis Clinical Research Consortium is pleased to let you know the Mayo Clinic, Rochester, MN, and Johns Hopkins Vasculitis Center, Baltimore, MD is now enrolling patients for our study: VCRC Genetic Repository One Time DNA Protocol.

My rheumy's have been with me since the beginning and I am responding well to their prescribed treatments. I am going to email them back to let them know I was only interested in the genetic repository. The closer they come to finding a cause means that they are that much closer to finding a cure.
