Spondylo-epi-metaphyseal dysplasia with joint laxity (SEMDJL) is characterized by severe dwarfism, articular hypermobility and progressive spinal malalignment. The clinical manifestations of 18 affected persons in 13 families of the Afrikans-speaking community of South Africa have been analysed and it has become evident that survival into adulthood is unusual. SEMDJL is inherited as an autosomal recessive trait.
