What can genetics contribute to reduce the problems of schizo-affective psychoses?

The biological base of psychoses is controlled by multifactorial genotype compounds using sometimes the same gene locus or DNA information section for diverse diseases, but always in different and repeatable combinations. These compounds can be formed by special regulatory or junction genes. With the help of inherited serum markers of the haptoglobin and the Gc system including quantitative studies of the ceruloplasmin and transferrin serum level, the combinations of diverse biological factors have been presented especially for cycloid psychoses, unsystematic schizophrenias, and paranoid psychoses with late onset and a cyclic axis syndrome. Considering the specifications of genetic control and clinical course no indefinite mixtures in the sense of schizo-affective psychoses should be discussed furthermore.
