[edit] Discussion of Nail-Patella syndrome

  • AKA Fong syndrome
  • Nail-patella syndrome is an autosomal dominant condition characterized:
    • Nail dysplasia
    • Patellar aplasia-hypoplasia
    • Arthrodysplasia of the elbows
    • Iliac horns
    • Nephropathy


  • In the US, it has a prevalence of 1 per 50,000 live births.
  • Patients are at risk for nephropathy that resembles glomerulonephritis. This occurs in 30-55% of cases, and renal failure is the leading cause of death.
  • No race predilection has been reported.
  • Males and females are equally affected.

  • Patellar aplasia-hypoplasia
  • Iliac horns: These symmetrical, bilateral, central-posterior, iliac processes are asymptomatic and vary from a small dimple to a well-marked spur.
  • Elbow arthrodysplasia: The head of the radius is underdeveloped and posteriorly displaced.
