There is increasing evidence that genetic factors play a role in the etiology of schizophrenic disorders. One thousand eightynine first-degree relatives of schizophrenics and 1,137 controls were studied to discover their psychiatric morbidity. Psychiatric morbidity was found in 16.34% of the firstde

โฆ Synopsis
Platelet monoamine oxidase (MAO) is under genetic control. A lower MAO activity in chronic schizophrenia has repeatedly been reported, and it has been suggested that reduced activity of this enzyme reflects an increased vulnerability to schizophrenia. To test this hypothesis platelet MAO was determined in 65 first-degree relatives of 22 schizophrenic index patients and in matched healthy controls. No difference in mean activity between the two samples could be detected, suggesting that reduced MAO activity in schizophrenia is more likely to be a phenomenon secondary to the disease. A significant parent-offspring correlation of MAO activities was obtained.
