title: Linkage between glucose-6-phosphate dehydrogenase deficiency and manic-depressive psychosis.
abstract: Hereditary has been shown to be an important factor in the aetiology of manic-depressive psychosis. Recent linkage studies with colour blindness have suggested the presence of an X-linked dominant gene in the transmission of manic-depressive psychosis. We report here positive evidence of a linkage between manic-depressive psychosis and glucose-6-phosphate dehydrogenase deficiency in an informative family assorting for both traits. These results strengthen previous linkage studies in affective illness and support the hypothesis of X-linkage in a subgroup of manic-depressive psychosis.
