title: Identical twins with the classical form of Schwartz-Jampel syndrome.
abstract: The Schwartz-Jampel syndrome is a rare disorder inherited as an autosomal recessive trait. The main clinical features of this syndrome include generalized myotonic myopathy, skeletal dysplasia, blepharophimosis, microstomia, contracture of joints and short stature. This report concerns a pair of female monozygotic twins with Schwartz-Jampel syndrome. Minor physical differences were found in the toes and joints affected. Additionally, both showed severe microcephaly and previously undescribed X-ray manifestations: a small skull, disproportion between skull and facial structures and dysharmonic bone maturation. This is the first report of identical twins with this syndrome.
