Schinzel acrocallosal syndrome.

Acrocallosal syndrome (ACLS), also known by its synonyms: Schinzel Acrocallosal syndrome and Hallux duplication, Postaxial polydactyly and absence of corpus callosum, is a rare genetic disorder that is apparent at birth. Although autosomal recessive inheritence has been suggested, ACLS often appears to occur sporadically. Typical characteristics of ACLS are hypoplasia/agenesis of corpus callosum, moderate to severe mental retardation, characteristic craniofacial abnormalities, distinctive digital malformations and growth retardation. It has not been reported from India so far. This article reports a 5-month-old boy with combination of abnormalities consistent with acrocallosal syndrome.
