[Relation between paranoid psychoses and schizophrenia (according to genetic-correlation analysis)].

The author has made a genetic-correlational analysis of the findings obtained in a clinical-genealogical examination of two groups of probands--with paranoiac schizophrenia (40 families) and with progressive schizophrenia (365 families). The results of the analysis suggest that the studied forms of schizophrenia are of the same genetic nature. Simultaneously, a genotypical homogeneity of the paranoiac form of schizophrenia has been demonstrated.
