title: [Analysis of the allelic polymorphism of four short tandem repeats in a population from the northwestern region of Russia].
abstract: Characteristics of the allelic polymorphisms of the trimeric AGC repeat of the androgen receptor gene (Xq11-12), exon 1 (AR); the tetrameric ATCT repeat of the von Willebrand factor gene (12p12), intron 40 (vWF); the AGAT repeat of the hypoxanthine phosphoribosyltransferase gene (Xq26) (HPRT); and the AGAT repeat of anonymous DNA sequences of the short arm of chromosome X (STRX1) were studied in 160 DNA samples from unrelated inhabitants of northwestern Russia using the method of polymerase chain reaction. Seventeen, ten, eight, and nine alleles were revealed electrophoretically for short tandem repeats of AR, vWF, HPRT, and STRX1, respectively. The heterozygosity indices for these repeats were 0.80, 0.70, 0.54, and 0.58, respectively. The values for AR and vWF correlated with those expected, according to the Hardy-Weinberg equilibrium, whereas the values for HPRT and STRX1 differed significantly from those theoretically expected. The individualization potentials were 0.045, 0.135, 0.095, and 0.061 for the short tandem repeats of AR, vWF, HPRT, and STRX1, respectively. The distribution of genotypes for the set of these four loci in the population studied was determined. The possibilities of using the studied polymorphic marker systems in molecular diagnosis of the corresponding monogenic diseases--spinal and bulbar muscle atrophy (AR), Lesch-Nyhan disease (HPRT), and von Willebrand disease (vWF)--as well as in population human genetics, testing of personal identity, and molecular approaches to the estimation of mutagenic activity are discussed.
