ARPKD/NPHP | Change in sampling technique from invasive kidney biopsy to non-invasive "liquid biopsy" (urine sample).
|
BK Nephropathy | The RDG PPI has contributed to grant applications |
Calciphylaxis | Global leadership:
|
CKD African Genes | New APOL1 testing available at King's which can be offered to other units. This will be publicised when 'live'. |
Cystinosis | National Commissioning of the Cystinosis Centres: NHS England » Service specification: Cystinosis diagnosis and co-ordination of management (all ages).
National Commissioning of Cystadrops: NHS England » Mercaptamine hydrochloride viscous eyedrops for corneal cystine deposits in people aged 2 years and over.
Most of the RDG members energy has been focussed on setting up the hubs, which are still evolving but will profoundly change practice with anticipated patient benefit. There is a major phase 1 trial of the “CF10 prodrug” hopefully in 2024, which we will support. We will be supporting the International Cystinosis Network Europe Conference from 25 – 27 July 2024 in Manchester. |
Cystinuria | Approached by several Pharma companies regarding urine chelators. Improving patient care. A good exemplar of this was the National letter re tiopronin shortage we developed in 2021.

Fibromuscular Dysplasia | The main developments are the ethical approval of the UK FMD study, Salford Royal Hospital is the sponsor and are uploading patients to this study. 9 other centres (the RaDaR collaborators primarily) are in the process of onboarding. |
Hyperoxaluria | Creation of a virtual clinical pathway which is nationally available. Helping the NHS use high-cost drugs in a cost-effective way. Making genetic testing quicker and easier. |
IgA Nephrothaphy | First questionnaire out to an entire RDG; intention is to send these annually. Research plans are active and we wish to add QoL data to RaDaR. We have "virtually" linked RaDaR with the NIHR BioResource and this should reap rewards in the coming years. |
Inherited Renal Cancer Syndromes | Extensive recruitment has been achieved at one centre (Cambridge) and other centres are coming on board and are being prioritised. |
MPGN, DDD and C3G | Activity in C3G trials slightly outwith RaDaR; work done by RDG group members has led to publications. |
