NEPTUNE

The purpose of this study is to learn more about three kidney diseases called nephrotic syndrome: Focal Segmental Glomerulosclerosis (FSGS), Minimal Change Disease (MCD), and Membranous Nephropathy (MN). By collecting health information and laboratory samples from individuals who have these diseases and by making this information available to researchers, we hope to gain new knowledge about these diseases and to find better treatments for them.
