Case Report: Making a diagnosis of familial renal disease - clinical and patient perspectives.

BACKGROUND: A precise molecular genetic diagnosis has become the gold standard for the correct identification and management of many inherited renal diseases.

METHODS: Here we describe a family with familial focal segmental glomerulosclerosis, and include a clinical and patient perspective on the diagnostic workup and relaying of genetic results following whole exome sequencing.

RESULTS: Through next generation sequencing approaches, we identified a pathogenic mutation in TRPC6, the underlying cause of the phenotype. The identification of this mutation had important clinical consequences for the family, including allowing a living-unrelated kidney transplant to proceed in the index case. There are also wider ranging social and ethical dilemmas presented when reaching a genetic diagnosis like this one, which are explored here by both physicians and the index case.

CONCLUSIONS: Through physician and patient perspectives in a family with inherited renal failure we explore the implications and the magnitude of a molecular genetic diagnosis.
