title: [HLA groups in the infantile psychoses during development, and hypothesis for an enzyme defect].
abstract: The HLA typing (loci A and B) of a series of fifteen psychotic children has shown an increase of the frequency of both HLA-A9 and B5 antigens. These preliminary data and previous biochemical findings in psychotic patients lead the authors to postulate the hypothesis of a qualitative or quantitative anomaly of the superoxide dismutase (SOD-2), the gene of which is situated on the same chromosome (sixth) as the HLA complex.
