title: Clinical characteristics of schizophrenia associated with velo-cardio-facial syndrome.
abstract: Velo-cardio-facial syndrome (VCFS) is caused by a microdeletion in the long arm of chromosome 22 and is associated with an increased frequency of schizophrenia and bipolar mood disorder. The purpose of this study was to investigate the genetic, physical, developmental and psychiatric features of schizophrenic patients with VCFS microdeletion. It describes the clinical findings in four schizophrenic inpatients with the characteristic chromosomal deletion. The four patients displayed delayed motor development, language deficits, learning disabilities, mental retardation, early age of onset, chronic and disabling course of illness and poor response to classical neuroleptic drugs and electroconvulsive therapy. Two patients benefited from treatment with clozapine. We suggest that schizophrenic patients with a history of delayed motor development, early onset of the disorder, history of learning disability, mental retardation, congenital cardiac anomalies and/or hypernasal speech should be screened for the velo-cardio-facial syndrome deletion. The implications of this study for psychiatric phenotype, nosology, disease mechanism, and possible new treatments in the future are discussed.
