title: Population genetics of the D4S139, D10S28, D17S74 and D17S79 VNTR loci among Asian, black, Caucasian, Hispanic and Native American populations from Seattle.
abstract: We studied four variable number of tandem repeat (VNTR) loci (D4S139, D10S28, D17S74, and D17S79) in five ethnic populations from the Seattle metropolitan area. DNA samples purified from randomly chosen individuals were digested with Hae III or Hinf I and probed with pH30, for D4S139; TBQ7 for D10S28; pCMM86 for D17S74 and pAC256 for D17S79. The allele frequencies, expected Hardy-Weinberg values, observed heterozygosities and genetic distances among the populations were obtained for all these loci. D4S139 restriction fragment lengths (RFLs) varied in size from 1.4 to 22 kilobase pairs (kbp). The observed heterozygosities (H) varied from 84% in Native American populations to 94% among Blacks. D10S28 RFLs varied in size from 650 base pairs (bp) to 10.1 kbp. H varied from 90% in Native Americans to 96% in Caucasians and Hispanics. D17S74 RFLs varied in size from 782 bp to 9.3 kbp. H varied from 87% in Asians to 92% among Blacks. D17S79 RFLs varied in size from 400 bp to 3 kbp. H varied from 87% in Hispanics to 95% in the Black population. The frequencies of genotypes of the loci conformed to Hardy-Weinberg equilibrium with the exception of the D17S79 in Hispanics and Native Americans. The genetic distances between the populations were also determined.
