Prevalence of hereditary pathologies in residents of the Kirov Province

Medical-genetic study was carried out in the population of Kirov Province (population size about 120.000). 203 families with 334 affected with hereditary disorders were registered. The correctness of pathology classification for the inheritance type was confirmed by segregational analysis. The load of hereditary diseases in the population was: 1.25 +/- 0.06 for autosomal dominant, 1.37 +/- 0.07 for autosomal recessive and 0.22 +/- 0.06 for X-linked recessive disorders. It is suggested that variability in the values of the load of autosomal recessive disorders is determined to the large extent by genetic structure of the population.
