APRT Deficiency – RDG

  • Aims of the Group

    1.   To collect clinical data on patients with APRT Deficiency in a Registry. This will allow us to:

    • study the causes, natural history and outcome of the condition
    • develop patient cohorts for future studies

     

    2.   To collect biological samples for future studies in a Biobank. This will allow us to:

    • identify factors influencing the course of APRT Deficiency
    • determine the role of various genes

     

    3.  To develop new methods to measure urinary purine excretion. This will improve tools that allow us to:

    • study the effectiveness of pharmacological and dietary interventions
    • identify factors influencing the course of the condition

     

    4.  To work with patient organisations, health care professionals and researchers:

    • to enhance the education and training aspect of this project
    • to develop strategies to increase the awareness and early detection of APRT Deficiency and improve patient outcomes
  • Current Activities

    1. Enrolling patients into RaDaR

    Analysis of data from international registries has led to the publication of review papers and the development of diagnostic guidelines. These may be refined with the inclusion of UK data.

    2.  Improving ways of measuring DHA

    Our Icelandic colleagues have been developing a way to measure DHA in the urine to help diagnose APRT Deficeincy and monitor drug therapy.

    3. Conducting a pilot study with APRT Deficiency patients

    We are comparing the effect of two different drugs (allopurinol and febuxostat) and dietary modification on urinary DHA excretion.

  • International Links

    Because APRT Deficiency is such a rare condition, we aim to collaborate extensively with colleagues based in Iceland and the USA in order to achieve the aims of the group. Details of these collaborations can be found on the Rare Kidney Stone Consortium website.

  • Patient Support Groups

    The APRT Deficiency Support Network aims to increase awareness of all aspects of this underreported disease including its symptoms, diagnosis, available treatment options and current scientific research. Its website connects patients and relatives of those with APRT Deficiency to provide support and practical advice.
