As data on X-chromosomal short tandem repeats (X-STRs) for the Brazilian population are scarse, the aim of this study was to determine the allele frequencies of five X-STRs (DXS6854, DXS7424, DXS101, DXS6808 and DXS7132) in the São Paulo State, Brazil. No deviations from the Hardy-Weinberg equilibrium were observed, with the exception of DXS101. The forensic efficiency parameters demonstrated that DXS101 was the most informative marker. Population comparisons revealed that the X-STR profile sampled in the state of São Paulo was more similar to European and African populations than Asiatic populations reported in this work.
由于巴西人群X染色体短串联重复序列（X-STRs）的数据稀缺，本研究旨在确定巴西圣保罗州五个X-STRs（DXS6854、DXS7424、DXS101、DXS6808和DXS7132）的等位基因频率。除DXS101外，未观察到偏离哈迪-温伯格平衡的情况。法医效率参数表明，DXS101是信息最丰富的标记。人群比较显示，圣保罗州采集的X-STR图谱与欧洲和非洲人群比与本研究中报道的亚洲人群更相似。
