[Hereditary polymorphism in the haptoglobin system of schizophrenic patients and healthy subjects].

Hereditary polymorphism of haptoglobin is studied by means of starch gel electrophoresis in schizophrenic patients (200 persons) and in healthy people (154 persons), in habitants of Minsk. It is concluded that Minsk inhabitants do not differ considerably from the rest European population in their frequencies of haptoglobin alleles. No reliable differences in the distribution of haptoglobin genotypes were found between patients and healthy persons. However, hereditary types of haptoglobins turned to be markers of the course and the prognosis of schizophrenia.
