The acrocallosal syndrome

Abstract
We report two unrelated patients, a three‐year‐old girl and an 8 8/12‐year‐old boy with the newly described “acrocallosal” syndrome. The main manifestations of the syndrome are unusual facial appearance, pre‐ and postaxial polydactyly, mental retardation, and absence of the corpus callosum. Cause remains unknown.
