Genetic polymorphisms of blood groups, serum proteins, red cell enzymes, PTC tasting, and cerumen types are reported for five Mongoloid populations of Buryats from the Lake Baikal region of Siberia (Russia). These groups are characterized by relatively high frequencies of alleles ABO*B, RH*D, cerumen D, GC*1F, ACP1*B, ESD*2, and PGD*C. Significant genetic heterogeneity between populations was demonstrated for the loci RH, MN, cerumen, PGD, ABO, GC, GLO, TF, and PGM1. Genetic distance analyses using five loci revealed a lower level of genetic microdifferentiation within the Buryat populations compared with other native Siberian groups. The distribution of gene markers in Buryats is similar to that found in neighboring Central Asian groups, such as the Yakuts and the Mongols. Intrapopulational analyses of the five Buryat subdivisions, based on R matrix and rii, indicate that one of the subdivisions is reproductively more isolated than the others and that two of the communities have received considerable gene flow. A nonlinear relationship was demonstrated between geographic and genetic distances of Buryat population subdivisions.

Genetic polymorphism at 10 independent loci (ABO, RH, HP, GC, PI, TF, ACP1, PGM1, GLO1, and PTC) was studied in male patients with lung squamous cell carcinoma. These patients were divided into two groups, depending on their tolerance for surgical intervention and on the postoperative course: (1) patients with an uneventful postoperative period and (2) patients with postoperative complications. The genetic structure of the combined sample at the loci studied did not differ from that of the control group consisting of health people (population control). Genotypic differences might manifest at the postoperative stage rather than at the onset of the disease, and determine the presence of postoperative complications. However, comparative analysis of the two groups of patients revealed their polar divergence in respect to phenotype and gene frequencies at certain loci. Moreover, the genotypic structure of patients in both groups differed from that in the combined sample and in the population control. In the group with postoperative complications, higher frequencies of the alleles GC*1F, ACP1*A, and HP*2 were observed. By contrast, the group of patients with an uneventful postoperative period demonstrated prevalence of the alternative alleles of these loci: GC*2, ACP1*B, and HP*1. The greatest difference in the distribution of informative allele frequencies was observed between the group of patients with postoperative complications and the control group. This is evidence that these groups significantly differ in their genetic structure. Such divergence is largely determined by the polymorphic multifunctional systems of serum proteins.

Relationships between genetic polymorphisms (ABO, RH, HP, TF, GC, Pi, ACP1, PGM1, GLO1, PTC) and some clinical, biochemical, and functional parameters were studied in patients with epidermoid carcinoma of the lung who were divided into 2 groups: those with uncomplicated and complicated postoperative courses of the disease. They were found to be different in the two groups. The values of ESR, albumin, lymphocytes, vital capacity, and RQ are the most distinctive signs that differentiate the patient groups. A high correlation was found between the signs in patients with an uncomplicated postoperative course. A less correlation between the signs, as a higher intergroup variability in the majority of the signs under study suggests that there is a significantly impaired physiological homeostasis in the group of patients with a complicated course. Comparing the mean values and dispersions shows their equal direction in the two groups of patients irrespective of their genetic polymorphism. The GC system is associated with profound changes of the studied signs in the group of patients with an uncomplicated course and GC*1F carriage should be regarded as a poor factor in the prognosis of the disease.

Population genetic data on Gagauzes from Moldavia are reported here for the first time. AB0 and Rhesus blood groups, serum protein group (HP, TF, GC) and the red cell enzyme polymorphism PGM1 were determined in 190 Gagauzes. In addition to this the ability to taste PTC was tested. The following allele frequencies were found: AB0*0 = 0.5241, AB0*A = 0.3279, AB0*B = 0.1480; RH*D = 0.6083, RH*d = 0.3917; HP*1 = 0.3544, HP*2 = 0.6456; TF*C1 = 0.7472, TF*C2 = 0.1770, TF*C3 = 0.0730, TF*B = 0.0028; GC*1F = 0.1025, GC*1S = 0.5932, GC*2 = 0.3043; PGM*1+ = 0.5932; PGM*1- = 0.1000, PGM*2+ = 0.2607, PGM*2- = 0.1107. The frequency of the PTC*T allele was found to be 0.5298. These frequencies and genetic distance analyses show that the gene pool of the Gagauzes is similar to that of neighbouring southeastern European populations.
