Recurrence Post-transplant Observational Study in Focal Segmental Glomerulosclerosis and Minimal Change Disease

After a kidney transplant, sometimes focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) return in the new kidney. This study is being done to try to understand why this happens in some people but not in others. The purpose of RESOLVE is to gather a group of people with FSGS and MCD that have had or will have a kidney transplant to create a bank of information and biospecimens so researchers can more effectively study these diseases.

Inclusion Criteria:Retrospective non-consented participant group had a transplant from the year 2000 and onward.Diagnosis of FSGS or MCD in the native kidney (prior to transplant).Exclusion Criteria:Pathologic diagnosis other than FSGS or MCDFSGS or MCD secondary to a known disorder (e.g. lupus nephritis, Immunoglobulin A (IgA) nephropathy, malignancy)
