The association of a spondylo-epiphyseal dysplasia and growth failure with the nephrotic syndrome was found in three boys. Renal biopsy performed on two revealed focal and segmental glomerulosclerosis. The nephrotic syndrome occurred at the age of 3-7 years, leading to end-stage renal failure in all patients. Growth failure persisted after successful renal transplantation. This association may represent a distinct disease entity.
