Observational Studies

The Nephrotic Syndrome Study Network


The Nephrotic Syndrome Study Network (NEPTUNE) is a 24-site consortium designed to foster clinical and translational research to redefine nephrotic syndrome on a mechanistic level and to translate new discoveries to the bedside. The NIH sponsored consortium is coordinated at the University of Michigan with a focus on patients with Focal Segmental Glomerulosclerosis (FSGS), Minimal Change Disease (MCD), Membranous Nephropathy (MN) or childhood onset nephrotic syndrome. 

NEPTUNE includes a) longitudinal cohort study with biospecimens and data collection for use in scientific discovery and b) a biology-based patient to clinical trial matching program, NEPTUNE MATCH. Learn more at https://neptune-study.org.

Cure Glomerulonephropathy


Glomerulonephropathy (CureGN) is a 66-center consortium that fosters research through a prospective observational study and biobank with 2,400 patients with glomerular disease.

Funded by the NIH-NIDDK, University of Michigan manages the CureGN data coordinating center. Participating children and adults with FSGS, MCD, MN, or IgA nephropathy graciously share their clinical data, patient-reported data, biospecimens and insight to support clinical and translational research.

Kidney Research Network [KRN]

Kidney Research Network

The mission of the KRN is to improve kidney disease treatment options and optimize patient health. KRN engages patients, medical teams, researchers, patient advocates, regulatory, and industry partners to accelerate research to find better treatments with a focus on rare kidney diseases.

The KRN, coordinated by the University of Michigan Pediatric Nephrology Research Program, includes a Patient Registry of 1,200 participants with proteinuric kidney disease who consent to share data from their electronic health records; Clinical Trials Consulting and Endpoints Consortium to improve clinical trial designs and trial endpoint options. Quality Improvement Program to improve the care provided to patients with kidney disease Learn more at https://www.kidneyresearchnetwork.org



The Clinical Phenotyping Resource and Biobank Core (C-PROBE) is a prospective observational cohort study of 1,600 patients with chronic kidney disease. C-PROBE includes a wide range of diagnoses, including glomerular and non-glomerular diseases. Clinical data collection is couples with biobanked specimens to foster translational research.

Chronic Kidney Disease in Children (CKiD)

Chronic Kidney Disease

The CKiD Study is a NIH-funded, multicenter, prospective cohort study of children aged 6 months to 16 years with mild to moderate impaired kidney function.

The primary goals of CKiD are to determine the risk factors for decline in renal function and to define how progressive decline in renal function impacts biomarkers of risk factors for cardiovascular disease; neurocognitive function and behavior; and growth failure and its associated morbidity.
