The Nail-Patella syndrome (NPS) is an autosomal dominant connective-ti
ssue disorder characterized by the absence or hypoplasia of the nails
and patella, posterior illiac horns, elbow deformities, congenital nep
hropathy cervical ribs and eye problems. The presence of the posterior
iliac horns is pathognomonic and have been observed in more than 80 p
er cent of cases. In this report, we present the first case of prenata
l diagnosis of NPS by ultrasound. The possible kidney involvement, com
bined with other, milder. complications make the prenatal diagnosis of
this syndrome worthwhile. (C) 1998 John Wiley & Sons, Ltd.
