The aim of this study was to contribute new data on autosomal STR and Y-STR markers of the Mayas from Guatemala in order to improve available databases of forensic interest. We analyzed 16 autosomal STR markers in a population sample of 155 indigenous Maya and 17 Y-chromosomal STR markers in the 100 males of the sample. Deviations from Hardy-Weinberg equilibrium and linkage disequilibrium between autosomal STR markers were not observed at any loci. The combined power of exclusion was estimated as 99.9991% and the combined power of discrimination was >99.999999999999%. Haplotype diversity of Y-STRs was calculated as 0.9984 ± 0.0018 and analysis of pairwise genetic distances (Rst) supported the Native American background of the population.
本研究的目的是提供危地马拉玛雅人的常染色体STR和Y-STR标记的新数据，以完善法医相关的现有数据库。我们分析了155名玛雅原住民群体样本中的16个常染色体STR标记，并在样本中的100名男性中分析了17个Y染色体STR标记。在任何位点均未观察到常染色体STR标记偏离哈迪-温伯格平衡和连锁不平衡。排除组合概率估计为99.9991%，鉴别组合概率>99.999999999999%。Y-STR的单倍型多样性计算为0.9984±0.0018，成对遗传距离（Rst）分析支持该群体的美洲原住民背景。
