Lessons learned from a multidisciplinary renal genetics clinic.

BACKGROUND: Inherited renal disorders comprise a significant proportion of cases in both paediatric and adult nephrology services. Genetic advances have advanced rapidly while clinical models of care delivery have remained static.

AIM: To describe a cohort of patients attending a multidisciplinary renal genetics clinic and the insights gained from this experience.

DESIGN AND METHODS: A retrospective review of clinic cases and their molecular genetic diagnosis over a 5-year period.

RESULTS: We report details of 244 individuals including 80 probands who attended the clinic. The commonest reasons for referral was familial haematuria which accounted for 37.5% of cases and cystic kidney disease, accounting for 31% of cases. Eighteen probands had a known molecular genetic diagnosis and were referred for genetic counselling and screening of at risk relatives and management plans. About 62 probands and their families were referred for a precise molecular diagnosis and this was achieved in 26 cases (42%). The most frequent new genetic diagnoses were COL4A5 mutations underlying familial haematuria and familial end stage renal disease. The clinic also allowed for patients with rare renal syndromes to be reviewed, such as ciliopathy syndromes, allowing detailed phenotyping and often a precise molecular genetic diagnosis to be provided.

CONCLUSIONS: The integration of modern day genetics and genomics into multidisciplinary clinics often allows a precise diagnosis which benefits patients, their relatives and the clinicians providing care and future management.
