Abstract
We report on a patient of Guatemalan descent whose physical and radiological findings are consistent with a diagnosis of spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL). This is a rare, autosomal recessive skeletal dysplasia with short limbs, severe scoliosis, high dorsal kyphoscoliosis, and joint hypermobility. Most described patients with SEMDJL are from the Afrikaans-speaking communities of South Africa. Patients with SEMDJL have an oval face, prominent eyes, and blue sclerae. Our patient's height and weight were below the fifth centile. She had prominent eyes with blue sclerae, a narrow, high-arched palate, pectus carinatum, severe scoliosis, and hyperextensibility and instability of most joints, with limited extension and supination of her elbows. A review of her roentgenograms showed severe scoliosis, poorly developed ischial, iliac, and pubic bones, a "bat-like" appearance of the iliac bones, "dysplastic" acetabulum, minimal metaphyseal and epiphyseal abnormalities at the knees, deformation of the proximal femoral metaphyses, and generalized brachydactyly of the hands and feet. This disorder may be more common than previously thought, and the diagnosis should be considered in any child with a dwarfing condition and joint laxity.
