The National Registry of Rare Kidney Diseases (RaDaR) was set up with funding from Kidney Care UK and Kidney Research UK and is supported and coordinated by the UK Kidney Association. There are over 100 NHS sites contributing to RaDaR. To date, 32,924 UK patients have been recruited (up to March 2024).

RaDaR focuses specifically on rare renal conditions and holds detailed information on people with these conditions. More information about each condition and RaDaR recruitment is on the Rare Renal microsite.
