Lethal short-rib polydactyly syndrome of the Majewski type: a report of three cases.

Three cases of lethal short-rib polydactyly syndrome of the Majewski type are presented. All three cases were the products of first-cousin marriages. Two of the cases were siblings; three more of their siblings also showed signs of this abnormality but their cases were incompletely documented. The three reported cases are compared with five fully documented cases that have been presented by other authors.
