The nature of the association between the ABO blood groups and disease is being investigated in the population of the State of Iowa.1 The demonstration of statistically significant associations between the ABO blood groups and several diseases suggests that the ABO blood groups may be a tool useful in investigation of genetic factors in still other disorders. This paper is a report of the findings in patients with psychoses and intracranial neoplasms (brain tumors).
