Kidney abnormalities in Hajdu-Cheney syndrome.

We report a 14-year-old boy from Saudi Arabia with the Hajdu-Cheney syndrome who also had bilateral hypoplastic kidneys and chronic renal failure. This report, along with others in the literature, suggest that renal abnormalities, including cystic disease, vesico-ureteral reflux, glomerulonephritis, chronic renal failure, and hypertension, may be an integral part of this syndrome. Recognizing this fact, may help in the early diagnosis, prevention, and treatment of renal failure in these patients.
