HLA Antigens in Schizophrenia: A Family Study

Abstract
HLA haplotypes A and B were studied in eight familes with two or more schizophrenic members. All index cases and all but two sick relatives satisfied Research Diagnostic Criteria for the diagnosis of schizophrenia; 45 subjects were studied. Data were analysed by sequential tests for the detection of linkage and by the affected sib-pair method. The results do not support a linkage between HLA and schizophrenia.
