The short rib (polydactyly) syndrome Beemer type is a rare lethal osteochondrodysplasia characterized clinically by short limbs, median cleft upper lip and palate, narrow thorax, and protuberant abdomen, and radiologically by short ribs, short and bowed long bones, and mild platyspondyly. Two affected female sibs are described, one having a preaxial polydactyly of the feet. The differentiation with the short rib syndrome Majewski type relies mainly on the radiological appearance of the tibia. Molecular biology may eventually prove whether the 2 conditions are truly separate entities or not.
