Allele frequencies for 10 STR loci in a population from central Poland

Allele frequencies of 10 STR loci included in the AmpFlSTR SGM Plus Kit (PE Applied Biosystem) was obtained a simple of 222 unrelated individuals residing in Warsaw (Poland) region.     

珠海地区汉族人群10个Y-STR基因座的多态性

目的 调查珠海地区汉族人群10个Y-STR基因座及其单倍型的遗传多态性，探讨其法医学应用价值。方法 应用Y-PLEX荧光标记复合扩增系统，对珠海地区汉族200名无关男性个体进行10个Y-STR基因座的复合扩增，用ABI310型基因分析仪对扩增产物进行检测，统计10个Y-STR基因座的群体遗传学参数。结果 9个Y-STR基因座分别检出5、6、6、5、4、5、5、5、7个等位基因，DYS385基因座检出44种单倍型；GD值最低为0.3904(DYS391)，最高为0.9497(DYS385)；10个Y-STR基因座共同构成的单倍型161种，其中134种单倍型只出现1次，20种单倍型出现2次，3种单倍型出现3次，3种单倍型出现4次，1种单倍型出现5次，累计GD值为0.9948。结论 10个Y-STR基因座具有较高的个体识别能力，可应用于法庭科学中的个体识别与亲权鉴定。     

Allele frequencies and population data for 17 Y-STR loci (AmpFlSTR Y-filer) in a Northern Portuguese population sample

Allele frequencies and population data for 17 Y-STR loci included in a new commercial kit that has recently been available, the AmpFlSTR Y-filer PCR amplification kit (Applied Biosystems), that permits the simultaneous amplification of all the markers included in the actually used European "extended haplotype", DYS19, DYS189I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385I/II, DYS438, DYS439 and also DYS437, DYS448, DYS456, DYS458, DYS635 and Y GATA H4, were obtained from a sample of 175 healthy unrelated males and 45 father-son pairs from the North of Portugal. A total of 171 haplotypes were identified, of which 167 were unique and 4 were found in 2 individuals. The haplotype diversity (99.97%) and discrimination capacity (95.43%) were calculated. We report some non-standard situations, such as allele duplications and mutations. We also report a case of disputed paternity in which duplicated alleles plus an inconsistency of the transmitted alleles appeared.     

Allele frequencies for nine PCR-typed STR loci in a population from middle China

Allele frequencies for nine STR loci namely, CSF1PO, D5S818, D8S1179, F13A01, F13B, TPOX, HUMvWA, HUMFGA and D3S1358 were obtained from a Chinese Han population from Henan province (middle China).     

A Spanish population study of 17 Y-chromosome STR loci

Haplotype, allele frequencies and population data of 17 Y-chromosome STR loci DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460 (GATA A7.1), DYS461 (GATA A7.2), GATA A10, GATA C4 and GATA H4 were determined from a sample of 148 unrelated male individuals from Spain. A total of 144 haplotypes were identified by the 17 Y-STR markers, of which 141 were unique, two were found in two individuals and one was found in three individuals. The haplotype diversity (99.95%) and discrimination capacity (97.30%) were calculated. Comparisons were made with previously published haplotype data on other Iberian population samples and no significant differences were found.     

Allele frequencies data and statistic parameters for 13 STR loci in a population of the Brazilian Amazon Region

Allele frequencies for 13 short tandem repeat (D3S1358, vWA, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPOX, D16S539, CSF1PO, D8S1179 and FGA) loci were determined in a sample of 325 unrelated individuals from the population of the Amazon of Belém, Brazil. These loci are the most commonly used in forensic and paternity testing. The forensic parameters investigated presented high values. The power of discrimination and the probability of exclusion for these 13 STRs are 99.999999999992% and 99.9998%, respectively. In conclusion, these 13 markers are suitable for forensic analysis and paternity tests of the Amazonian population.
