There are several different types of glomerular diseases, such as minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), membranous nephropathy (MN), and immunoglobulin A nephropathy (IgAN). Over time, these diseases may cause kidney damage. Because these kidney diseases are rare, it is difficult for individual researchers to gather a large enough number of people to effectively study underlying causes, identify markers of disease, and identify and evaluate new therapies. The purpose of CureGN is to gather a group of people with glomerular disease to create a source of information and blood and urine samples, so that researchers can easily and effectively study glomerular disease. People with diabetes were excluded from the original CureGN Study, but diabetes is very common and may impact numerous aspects of glomerular disease. CureGN-Diabetes is an ancillary study to CureGN, which includes participants with diabetes AND glomerular disease, so researchers may also understand how these two chronic diseases affect one another.

You may be eligible for this study if you meet the following criteria:

• Conditions: glomerular diseases
• Age: 18 years - 99 years
• Gender: All
