Spondyloepiphyseal Dysplasia, Congenital
National Organization for Rare Disorders, Inc.
- SED Congenital
Congenital spondyloepiphyseal dysplasia is a rare genetic disorder characterized by growth deficiency before birth (prenatally), spinal malformations, and/or abnormalities affecting the eyes. As affected individuals age, growth deficiency eventually results in short stature (dwarfism) due, in part, to a disproportionately short neck and trunk, and a hip deformity in which the thigh bone is angled toward the center of the body (coxa vara). In most cases, affected individuals may have diminished muscle tone (hypotonia), abnormal front-to-back and side-to-side curvature of the spine (kyphoscoliosis), abnormal inward curvature of the spine (lumbar lordosis), and/or unusual protrusion of the breast bone (sternum), a condition known as pectus carinatum. Affected individuals also have abnormalities affecting the eyes including nearsightedness (myopia) and, in approximately 50 percent of cases, detachment of the nerve-rich membrane lining the eye (retina). Congenital spondyloepiphyseal dysplasia is inherited as an autosomal dominant trait.
