A term infant with prenatally noted ambiguous genitalia and nonpalpable gonads presented with life-threatening hyponatremia, hypertension, acidosis, and anuric renal failure requiring peritoneal dialysis at age 3 months.Sequencing confirmed 46, XY Denys-Drash syndrome (DDS) due to heterozygous Wilms tumor-1 exon 8 mutation encoding p.His445Arg. Renal US identified bilateral multifocal renal masses at age 8 months. Bilateral retroperitoneal nephrectomies found bilateral nephroblastomatosis without Wilms’ tumor avoiding chemotherapy, followed by bilateral laparoscopic orchiopexies. We suggest monthly screening of 46, XY DSD cases for DDS by evaluating for proteinuria and electrolyte disarray starting at diagnosis of DSD to prevent acute life-threatening renal failure presentation.
