Fabry disease is a lysosomal storage disorder with kidney involvement. The initial manifestation of kidney disease is often impaired urinary concentrating ability in adolescence or young adulthood. We describe a boy diagnosed prenatally with Fabry disease who presented with polyuria, polydipsia, hypertension, hypokalaemia and proteinuria at 7 years of age. A formal water-deprivation test followed by vasopressin challenge confirmed nephrogenic diabetes insipidus. A renal biopsy revealed findings typical of Fabry disease. Angiotensin converting-enzyme therapy resulted in rapid improvement of symptoms, normalization of blood pressure and resolution of hypokalaemia and proteinuria. This child is the youngest reported Fabry disease patient with documented renal pathology and clinical manifestations of hypertension, proteinuria and nephrogenic diabetes insipidus.

The purpose of this review is first to describe the importance of early detection of vasopressin receptor mutations responsible for X-linked nephrogenic diabetes insipidus (NDI). We have proposed that all families with hereditary diabetes insipidus should have their molecular defect identified because early diagnosis and treatment of affected infants can avert the physical and mental retardation that results from repeated episodes of dehydration. Secondly, 95 published missense mutations responsible for X-linked NDI are likely to result in misfolded arginine-vasopressin V(2) receptors that are trapped in the endoplasmic reticulum. These misfolded receptors are unable to reach the plasma membrane in principal collecting duct cells and to engage the circulating antidiuretic hormone, arginine-vasopressin. These misfolded proteins potentially could be rescued with pharmacologic chaperones, an active area of research pertinent to other hereditary protein misfolding diseases such as cystic fibrosis, phenylketonuria, and Anderson-Fabry disease among many others. Finally, a long-term careful surveillance of all patients with hereditary NDI should be performed to prevent chronic renal failure likely caused by the long-term functional tract obstruction with reflux.
