[Dynamic evaluation of the incidence of hereditary pathology by an accounting of spontaneous abortions and congenital developmental defects].

A new method is suggested to control the mutation process in man by the dynamics of hereditary pathology frequency. The paper presents data on registration of spontaneous abortions, congenital malformations, Down's syndrome and perinatal death in Angarsk for 10 years (1971-1980). No changes are found in the frequencies of these data. The dynamic analysis of hereditary pathology "units" of mutation origin for 10 years did not show any time trend.
