Original Article

Thirteen tetranucleotide and 2 pentanucleotide repeat units were analyzed in 120 unrelated individuals of Patel and other communities of Gujarat, India. Allele frequency data obtained from the analysis of 15 short tandem repeat markers of the population were found to be satisfying Hardy-Weinberg equilibrium, with marginal deviations. Departures from Hardy-Weinberg equilibrium were observed in Patel communities at locus vWA and for that of the other communities at locus D7S820 and at locus TPOX. The power of discrimination values on an average fall within the range of 0.718 and 0.870, with deviations at locus D3S1358 showing a value of 0.400 for Patels. The value ranged between 0.709 and 0.869, with slight variations among the studied alleles in the other group. Thus, the 15 markers selected for this study were found to be highly suitable in human identification and for providing information on genetic polymorphism of the population of Gujarat.
