Screening will be performed by the Principal Investigator during the kidney transplant evaluation clinics and during the wait list kidney transplant evaluation clinic. All patients with FSGS will have maintenance immunosuppression with belatacept (if EBV positive), prograf, cellcept and prednisone. If after one year the patient has been stable and there has not been rejection, will stop the prograf and continue solely with belatacept, cellcept and prednisone.
