The physical, radiographic, and pathologic findings in 3 new patients with Marden-Walker syndrome (MWS) are compared with those of previously described children with the syndrome. Over 75% of the children with MWS have blepharophimosis, psychomotor retardation, small mouth, micrognathia, kyphosis/scoliosis, and multiple contractures. Minimal diagnostic criteria have yet to be defined attesting to the broad range of variability and potential genetic heterogeneity in this disorder.
