A case of Potter sequence with WT1 mutation.

Wilms tumor 1 (WT1) is the causative gene of Denys-Drash syndrome and Frasier syndrome, and in most cases, kidney failure develops after birth. We report an unusual case of Potter sequence due to fetal nephropathy and kidney failure with a WT1 mutation. The neonate was born at 37 weeks of gestation, and had no distinctive facial appearance or anomalies of the extremities.
