RaDaR Protocol

The National Registry of Rare Kidney Diseases (RaDaR) is an initiative established by the Renal Association. It is designed to pull together information from patients who have certain rare kidney diseases. The aim is to give a much better understanding of how these illnesses affect people and facilitate research.

The work is done in partnership with patients. Where the research leads to practical benefits, such as better diagnosis, treatments or general advice this will be publicised on the website.

RaDaR is open for recruitment for children and adults with the following conditions:

  • Adenine Phosphoribosyltransferase Deficiency (APRT-D)
  • Alport Syndrome
