Abstract

This is a report of two North American patients with spondyloepimetaphyseal dysplasia with joint laxity, an uncommon autosomal recessive skeletal dysplasia rarely reported outside of South Africa. Patients with SEMDJL have vertebral abnormalities and ligamentous laxity that results in spinal misalignment and progressive severe kyphoscoliosis, thoracic asymmetry, and respiratory compromise resulting in early death. Nonaxial skeletal involvement includes elbow deformities with radial head dislocation, dislocated hips, clubbed feet, and tapered fingers with spatulate distal phalanges. Many affected children have an oval face, flat midface, prominent eyes with blue sclerae, and a long philtrum. Palatal abnormalities and congenital heart disease are also observed. Diagnosis in infancy may be difficult because many of the typical findings are not apparent early and only evolve over time. We review the physical and radiographic findings in two unrelated patients with this disorder in order to increase the awareness of this disorder, particularly for clinicians outside of South Africa.
