THE NAIL-PATELLA syndrome (hereditary osteo-onychodystrophy) is a rare, genetically determined disorder involving tissues of both ectodermal and mesodermal origin. Though the commonly affected sites of dysplasia are the patellae, the nails, and the elbows, other defects are often present. Since 1946, several investigators have commented upon the associated finding of proteinuria and hematuria in this syndrome suggesting glomerular involvement.1-8 The renal pathology in this disorder has not been fully delineated, nor have ultrastructural changes from the kidney been reported. It is the purpose of this report to describe additional clinical findings in an affected patient and further to define morphologic changes observed in the kidney by use of both light and electron microscopy.
