Renal tubular dysgenesis and mutation in the renin gene

Renal tubular dysgenesis is a severe and rare disorder of the renal development characterized by fetal anuria, oligohydramios and early death from pulmonary hypoplasia and refractory arterial hypotension. We report on a female patient who presented with anuria in the neonatal period, requiring peritoneal dialysis until 5 months of age with unexpected diuresis recovery at 2 months of age. Clinical, histological and pathophysiological issues are discussed for this disease related to a mutation in the renin gene. (c) 2007 Elsevier Masson SAS. Tous droits reserves.
