    Abstract:
    Analysis of properties of the genetic structure in 2847 individuals with different chronic diseases (1261 men and 1586 women) for 14 polymorphic loci (AcP, PGM1, PGD, GPT, GLO-I, EsD, AK, Pp, E2, Hp, Gc, Tf, AB0 and Rh) is presented. Discrepancy between the observed and expected phenotype frequencies for PGM1, GLO-I, EsD and AB0 loci is observed in a sample of patients Deviation from the expected frequencies is unequal for the representatives of different sex. Male and female portions of the sample differ significantly from each other for AcP, GPT, GLO-I, AK, EsD, Tf and AB0 loci, i. e. for 7 from 14 systems analysed. Highly significant differences between healthy and sick individuals have been detected: in general samples for 8 loci (AcP, PGM1, GPT, GLO-I, AK, Pp, Hp, AB0); in men for 8 loci (AcP, GPT, AK, PGD, Pp, Tf, AB0); in women for 5 loci (PGD, Pp, Gc, Tf, AB0). The difference between sick and healthy individuals of different sex is not only of qualitative but also of quantitative expression. The difference between sick and healthy men is much stronger, as compared to that between women. A decline in the average heterozygosity is noted in sick individuals. From the results obtained it is possible to conclude that the group of different pathologic conditions for the complex of genetic parameters differs significantly from that of healthy individuals. This may be a reflection of adaptation and disadaptation processes under the extreme environmental conditions.
