title: [Comparative analysis of allele polymorphism of three short tandem repeats in the Russian, Uzbek and Georgian populations].
abstract: The allele polymorphism of the AGC short tandem repeat (STR) of exon 1 of the androgen receptor (AR) gene located in Xq11-12, ATCT STR of intron 40 of the von Willebrand factor (vWF) gene located in chromosome 12p12, and AGAT STR of an anonymous DNA sequence (STRX1) from the short arm of the X chromosome was analyzed in the Georgian, Uzbek, and Russian populations. Polymerase chain reaction (PCR) with DNA of unrelated persons revealed 14 AR, 7 vWF, and 7 STRX1 alleles in Georgians; 14, 8, and 6 alleles, respectively, in Uzbeks; and 16, 8, and 9 alleles, respectively, in Russians. The heterozygosity at these STR was 0.61, 0.78, and 0.46 in Georgians; 0.60, 0.83, and 0.44 in Uzbeks; and 0.80, 0.70, and 0.58 in Russians. The correspondence of genotype frequencies to the Hardy-Weinberg equilibrium was observed with AR STR in Russians and Uzbeks, STRX1 STR in Georgians, and vWF in all three populations. A significant deviation from the equilibrium was found for STRX1 in Russians and Uzbeks and AR in Georgians. The potential of individualization was 0.05 for AR, 0.13 for vWF, and 0.18 for STRX1 in Georgians; 0.04, 0.09, and 0.13, respectively in Uzbeks; and 0.05, 0.14, and 0.07, respectively, in Russians. The allele and genotype frequency distributions of each STR were analyzed in all three populations. Allele frequencies in the populations were compared by the Kolmogorov-Smirnov test. The Russian population significantly differed in allele frequencies of the three STR from Uzbeks and in those of STRX1 and AR from Georgians. Georgians and Uzbeks significantly differed in vWF and STRX1 frequencies. The possibility of using the three STR in molecular diagnosis of the corresponding monogenic diseases, population genetic studies, and personal identification is discussed.
