Ehlers-Danlos syndrome, spondylocheirodysplastic type is a subtype of Ehlers-Danlos syndrome characterized by skeletal dysplasia comprising platyspondyly with moderate short stature, osteopenia and widened metaphyses, in addition to hyperextensible, thin, easily bruised skin, hypermobility of small joints with tendency to contractures, prominent eyes with bluish sclerae, wrinkled palms, atrophy of the thenar muscle and tapering fingers.
Features include always present findings: Hypertelorism, Depressed nasal bridge, and Webbed neck; and common findings: Flared metaphysis, Cigarette-paper scars, Motor delay, and Mild bone density loss (osteopenia) and others. 38 total HPO annotations.
