Abstract
The Pena–Shokeir phenotype represents an autosomal recessive syndrome characterized by neurogenic arthrogryposis, facial anomalies and pulmonary hypoplasia. Prenatal diagnosis of this disease has been reported prospectively and in cases with positive family history. We describe here a patient who has had three consecutive pregnancies affected by the Pena–Shokeir syndrome. In these pregnancies, the onset of the arthrogryposis varied between the 12th and the 18th week of gestation. Therefore, the possibility of a variable chronological development of the main diagnostic feature of the syndrome, arthrogryposis, has to be taken into proper consideration while counseling families with a positive history for the Pena–Shokeir phenotype.
