Cure Glomerulonephropathy Network (CureGN) is a multi-year study of 2,400 children and adults with four rare glomerular (kidney) diseases at over 50 centers in the US, Canada, and Italy. The purpose of CureGN is to create a patient research network to learn about four major causes of glomerular disease : 1. Minimal Change Disease (MCD) 2. Focal Segmental Glomerulosclerosis (FSGS) 3. Membranous Nephropathy (MN) 4. IgA Nephropathy (IgAN)

In this study, we are developing new magnetic resonance imaging (MRI) and ultrasound methods to determine if it is effective in diagnosing complication in kidney transplant patients. Participants in this study will involve patients that have had a kidney transplant and are scheduled for a kidney biopsy. The study will also involve a comparison group of healthy individuals that have no history of kidney conditions. Study procedures will include a review of medical history and medications, MRI scan and ultrasound of the abdomen and blood/ urine test.

Urinary stone disease (USD) is a common, chronic disorder that is seen more frequently in adolescence today than in the past. Current understanding of its impact on bone development and structure as well as dental health is not known. We will be evaluating bone and dental quality in 90 children/adolescents with USD and 90 healthy children/adolescents. The study requires: two to three visits for a total of three to four hours, that the participant be 5-21 years old, and compensation will be provided. If interested in participating contact the research coordinator at 267-226-6995.
