Acrocallosal syndrome, Schinzel type is a rare genetic disorder that is apparent at birth (congenital). Associated symptoms and findings may be variable, including among affected members of the same family (kindred). However, the disorder is typically characterized by underdevelopment (hypoplasia) or absence (agenesis) of the thick band of nerve fibers joining the two hemispheres of the brain (corpus callosum) and moderate to severe mental retardation. In addition, many affected individuals have malformations of the skull and facial (craniofacial) region and/or distinctive abnormalities of the fingers and toes (digits). Characteristic craniofacial abnormalities may include an unusually large head (macrocephaly) with a prominent forehead, widely spaced eyes (ocular hypertelorism), downslanting eyelid folds (palpebral fissures), a small nose with a broad nasal bridge; and malformed (dysplastic) ears. Most affected individuals also have distinctive digital malformations, such as the presence of extra (supernumerary) fingers and toes (polydactyly) and webbing or fusion (syndactyly) of certain digits. Additional physical abnormalities may also be present, including growth retardation, resulting in short stature. Although autosomal recessive inheritance has been suggested, acrocallosal syndrome often appears to occur randomly for unknown reasons (sporadically).
