    Abstract

    Based on a micro thermal cycler apparatus, a new protocol for amplification of the D1S80 locus has been developed. The advantages of this system consist of a reduction in time and costs of the amplification process, which greatly facilitates the analysis of the D1S80 locus at the population level and considerably increases its applicability in forensic samples. Using this protocol, an allele distribution study of the D1S80 locus has been carried out in a sample of 257 individuals residing in the Basque Country. In this study, up to 22 different alleles, ranging from 17 to 40 repetitions have been observed; moreover, the 35 and 38-repetition alleles, not reported in the european populations analyzed to date, have been detected.

    The sample studied fits Hardy-Weinberg equilibrium, the observed heterozygosity being 0.74, and the expected heterozygosity 0.804 ± 0.012. The Chance of Exclusion and Index of Discrimination are 0.638 and 0.072 respectively.

    Moreover, the gene frequency distribution from the Basque resident population does not show significant differences when compared to other European and U.S. Caucasian populations.
