Answer

The risk of schizophrenia is elevated in biologic relatives of persons with schizophrenia but not in adopted relatives. [16] The risk of schizophrenia in first-degree relatives of persons with schizophrenia is 10%. If both parents have schizophrenia, the risk of schizophrenia in their child is 40%. Concordance for schizophrenia is about 10% for dizygotic twins and 40-50% for monozygotic twins.
