Agenesis of the corpus callosum: symptoms consistent with developmental disability in two siblings

Abstract

Agenesis of the corpus callosum (AgCC) is a congenital disorder that disrupts the development of neurological structures connecting the right and left hemispheres of the brain. In addition to neurological symptoms, many individuals with AgCC demonstrate marked deficits in social, communication, and adaptive skills. This paper presents two case studies of congenital AgCC in siblings with socioemotional and behavioral symptoms consistent with developmental disability, but with notably different symptom presentations and clinical needs. Conclusions from these cases suggest that unique symptom profiles of individuals with AgCC warrant careful consideration for referral to appropriate academic and habilitative services.
