Abstract
It is well known that an individual with a family history of schizophrenia carries an increased risk of manifesting the disorder in comparison with members of the population at large. Also, within the population of schizophrenic patients, individuals may or may not have other members of the family affected. Obviously also, schizophrenic patients may be distinguished by gradations of severity of the illness. Whether familial incidence of schizophrenia and severity co-vary, however, remains an open question.
