Preferred Label : Spondyloepiphyseal dysplasia with congenital joint dislocations;
Symbol : SEDCJD;
CISMeF acronym : CDMD; HSD; SEDCJD;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Spondyloepiphyseal dysplasia, omani type; Chondrodysplasia with multiple dislocations; CDMD; Humerospinal dysostosis; HSD;
Description : Although patients with mutations in the CHST3 gene may initially be given varying
diagnostic labels, they have similar clinical features, including dislocation of the
knees and/or hips at birth, clubfoot, elbow joint dysplasia with subluxation and limited
extension, short stature, and progressive kyphosis developing in late childhood. The
disorder is usually evident at birth, with short stature and multiple joint dislocations
or subluxations that dominate the neonatal clinical and radiographic picture, and
affected individuals may receive an initial clinical diagnosis of Larsen syndrome
(see 245600) or humerospinal dysostosis. During childhood, the dislocations improve,
both spontaneously and with surgical treatment, and features of spondyloepiphyseal
dysplasia (SED) become apparent, leading to arthritis of the hips and spine with intervertebral
disc degeneration, rigid kyphoscoliosis, and trunk shortening by late childhood; at
this stage, the clinical features are those previously described as the Omani type
of SED (summary by Unger et al., 2010).;
