              • Definitions

                • Group of generalized skeletal dysplasias primarily involving vertebrae and proximal epiphyseal centers
                  • Affected patients demonstrate short trunk, neck, and limbs with normal hand and foot size
                • Classified as short-trunk dwarfing syndrome (trunk involvement > limbs)
                • 2 major SED types primarily seen: SED congenita and SED tarda
                  • Multiple rare uncommon subtypes also reported
