This study establishes the prevalence rates at birth of the skeletal dysplasias which can be diagnosed in the perinatal period or during pregnancy. Using a population-based register of congenital anomalies, a prevalence rate of 3.22 0/000 was observed. The most frequent types of skeletal dysplasia were achondroplasia and osteogenesis imperfecta (0.64 0/000, 1/15,000 births), thanatophoric dysplasia and achondrogenesis (0.28 0/000). The mutation rate for achondroplasia was higher in our material than in the other studies: 3.3 x 10(-5) per gamete per generation. Our study demonstrates that prenatal diagnosis by ultrasound is possible in some skeletal dysplasias.
