Abstract
Tibetans are considered an East Asian ethnic group and primarily live in the high Tibetan plateau, the western Sichuan and Yunnan mountains of central and southern China, and areas throughout the Himalayas and around the Tibetan plateau. These people exhibit rare molecular machinery that allows them to adapt to hypoxic environments in the Qinghai-Tibet Plateau and make them a potential candidate for providing insights related to medical genetic, molecular medicine and human population studies. In the current study, we have genotyped 549 individuals with Investigator Argus X-12 Kit. For 12 X-STRs, a total of 174 unique alleles were found, among them DXS10134 and DXS10135 were the most polymorphic loci. All of the loci were in Hardy-Weinberg Equilibrium (HWE). The numbers of observed haplotypes in Highlander Tibetans males were 161,112, 96 and 108, respectively, whereas haplotype diversities (HD) were 0.9959, 0.9880, 0.9809 and 0.9873, respectively. The combined discrimination power for males (PDm) was 0.999 999 99701 and for females (PDf) was 0.999 999 999 999 9958. This study represents an extensive report on X chromosomal STR markers variation in the Highlander Tibetans population for forensic applications and population genetic studies.

Abstract
With a unique inheritance pattern compared to autosomal short tandem repeats (A-STRs), X chromosomal STRs (X-STRs) have special usage in forensic relationship testing. In this study, we designed a multiplex amplification system (named TYPER-X19 multiplex assay) consisting of 18 STR loci spreading from 7.837 to 149.460 Mb on the X chromosomes (DXS9895, DXS8378, DXS9902, DXS6810, DXS7132, DXS10079, DXS6789, DXS7424, DXS101, DXS6797, DXS7133, DXS6804, GATA165B12, DXS10103, HPRTB, GATA31E08, DXS8377, and DXS7423), and the amelogenin. PCR primers were marked with four kinds of fluorophores including FAM, HEX, TAMRA, and ROX. The multiplex system was optimized and tested for precision, concordance, reproducibility, sensitivity, stability, DNA mixture, and species specificity according to the conventional validation guidelines. The results indicated that the system was accurate, reliable, and sensitive enough, and was suitable for common forensic case-type samples. In the population genetic study, a total of 148 alleles were detected at the 18 X-STR loci in 398 Southern Han Chinese. Relatively high combined power of discrimination in male (PDm ), power of discrimination in female (PDf ), mean paternity exclusion chance in trios (MECtrio ), and mean paternity exclusion chance in duos (MECDuo ) by Desmarais were detected, and HPRTB-DXS10103 was in linkage disequilibrium. The results suggested that the TYPER-X19 multiplex assay was suitable for forensic applications.

Gene 2018; 683:153-158. [PMID: 30326331 DOI: 10.1016/j.gene.2018.10.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 10/04/2018] [Accepted: 10/09/2018] [Indexed: 11/29/2022]
Abstract
X-chromosomal short tandem repeats (X-STRs) have been widely used in forensic practice involving complicated cases of kinship and also play an increasingly important role in population genetics. X-STRs have been studied in regional populations of China but there is a lack of data for the Manchu population. In this study, we have investigated the forensic genetic properties of 12 X-STRs in the Investigator Argus X-12 Kit (QIAGEN, Hilden, Germany) in 772 Manchu (male = 514, female = 258) individuals from the Xiuyan and Huanren Manchu autonomous counties of Liaoning province. We observed a total of 166 alleles at 12 X-STR loci with allele frequencies ranging from 0.001295to 0.615285. The most polymorphic locus was DXS10135 with 24 alleles while DXS7423 was the least polymorphic locus with 5 alleles. We found significant linkage disequilibrium (LD) between the following pairs of markers for males: DXS10103/DXS10101, DXS10135/DXS10146, DXS10101/DXS10148, DXS10135/DXS10148, DXS7423/DXS10148 and DXS10079/DXS10148. For females, LD was only observed for DXS10103/DXS10101. The combined power of discrimination was 0.9999999979699 for males and 0.999999999999998 for females. The numbers of observed haplotypes in Manchu males were 310, 172, 182 and 172 in four linkage groups; LG1, LG2, LG3 and LG4, respectively, however, these linkage groups did not form stable haplotypes as indicated by linkage equilibrium (LE) of STRs within the groups and significant LD between the groups. This study represents an extensive report on X-STR marker variation in the Manchu population for forensic applications and population genetic studies.

Abstract
This report identifies and characterizes 10 novel short tandem repeat (STR) loci on the human X chromosome, all of which are within a range of 1.1 Mb. These newly characterized loci were developed to aid in kinship assignment when the X chromosome is specifically required. The repeat DNA sequences were identified initially using data in GenBank and are located immediately upstream and downstream from the previously described locus DXS6807. Only those loci with seven or more observed alleles were used for further study resulting in the identification of 10 new loci. The distance between each pair of loci ranged from 24,998 to 244,701 bp with an average of approximately 110.8 kb. The number of observed alleles ranged from 7 to 30 for these 10 loci with a polymorphic information content ranging from 0.593 to 0.930. The LOD score from a pairwise linkage study ranged from 4.40 to 23.73, indicating that these 11 loci were highly linked, as expected. In line with standard forensic practice, all 11 loci can be amplified in one multiplex reaction, and comprehensive allelic ladders for all the loci have been constructed. These newly established 11 linked STR loci on the human X chromosome were found to be highly polymorphic and have the potential to aid in kinship testing where the X chromosome loci currently plays a role.

Abstract
The population genetic data and forensic parameters of 19 X-chromosome short tandem repeat (X-STR) loci in Chinese Uygur ethnic minority are presented. These loci were detected in a sample of 233 (94 males and 139 females) unrelated healthy individuals. We observed 238 alleles at the 19 X-STR loci, with the corresponding gene frequencies spanning the range from 0.0021 to 0.5644. After Bonferroni correction (P>0.0026), there were no significant deviations from Hardy-Weinberg equilibrium. The cumulative power of discrimination in females and males, and the probability of exclusion of the 19 X-STR loci were 0.999 999 999 999 999 999 998 091, 0.999 999 999 999 966, and 0.999 999 986 35, respectively. The cumulative mean exclusion chance was 0.999 999 992 849 in deficiency cases, 0.999 999 999 999 628 in normal trios, and 0.999 999 998 722 in duo cases. The high value of the forensic parameters mentioned above revealed that the novel panel of 19 loci had important values for forensic applications in the Uygur group.

Abstract
A new 19 X- short tandem repeat (STR) multiplex PCR system has recently been developed, though its applicability in forensic studies has not been thoroughly assessed. In this study, 932 unrelated individuals from four Chinese ethnic groups (Han, Tibet, Uighur and Hui) were successfully genotyped using this new multiplex PCR system. Our results showed significant linkage disequilibrium between markers DXS10103 and DXS10101 in all four ethnic groups; markers DXS10159 and DXS10162, DXS6809 and DXS6789, and HPRTB and DXS10101 in Tibetan populations; and markers DXS10074 and DXS10075 in Uighur populations. The combined powers of discrimination in males and females were calculated according to haplotype frequencies from allele distributions rather than haplotype counts in the relevant population and were high in four ethnic groups. The cumulative powers of discrimination of the tested X-STR loci were 1.000000000000000 and 0.999999999997940 in females and males, respectively. All 19 X-STR loci are highly polymorphic. The highest Reynolds genetic distances were observed for the Tibet-Uighur pairwise comparisons. This study represents an extensive report on X-STR marker variation in minor Chinese populations and a comprehensive analysis of the diversity of these 19 X STR markers in four Chinese ethnic groups.

Abstract
X-chromosomal short tandem repeats (X-STRs) have been widely used in forensic practices involving complicated ties of kinship over the past years, and also play an increasingly important role in population genetics. To study the genetic polymorphisms of 19 STR loci on X chromosome in Chinese Kazak ethnic group, we investigated the allelic and haplotypic frequencies of the 19 loci in 300 (149 males and 151 females) unrelated healthy individuals from Ili Kazak Autonomous Prefecture, Xinjiang Uigur Autonomous Region of China after having evaluated the forensic application value of these loci in forensic sciences, and then compared the population distinctions between the Kazak group and other reference groups. We observed a total of 240 alleles at these X-STR loci with the corresponding allelic frequencies ranging from 0.0017 to 0.5917. In the study, the highest polymorphism was found at DXS10135 locus. The combined power of discrimination in females was 0.999999999999999999999985 and in males 0.999999999999968. The present study indicates that the 19 X-STR loci are very useful for both forensic identification cases and kinship analyses involving a female offspring.

Abstract
Aim To analyze 8 X-linked short tandem repeat (STR) markers in the population of central Croatia and to evaluate their forensic efficiency. Methods We carried out a statistical analysis of the data from previously performed genetic analyses, collected during routine forensic work by the Forensic Science Centre ‘‘Ivan Vučetić.’’ Mentype® Argus X-8 PCR amplification kit was used for typing the data of 99 unrelated healthy women and 78 men from central Croatia. Haplotype frequencies were calculated only in male samples. Arlequin 3.5 software was used to assess Hardy-Weinberg equilibrium (HWE), linkage disequilibrium (LD), observed and expected heterozygosity. Power of discrimination (PD) for men and women, polymorphism information content (PIC), power of exclusion, and mean exclusion chance for deficiency cases, normal trios, and duos were determined using online database ChrX-STR.org. Results In female samples, deviations from HWE (P = 0.006) for each locus were not found. LD test performed both on female and male samples revealed no significant association between markers (P = 0.002). DXS10135 was the most polymorphic locus (PIC = 0.931). PD varied from 0.692 to 0.935 in male and from 0.845 to 0.992 in female samples. Combined PD reached 99.999999% in men and 99.9999999999% in women. Conclusion Performed analyses revealed that the studied marker set contained polymorphic markers with high power of discrimination. We can conclude that Mentype® Argus X-8 PCR kit is suitable for application in the population of central Croatia. Results of this study, together with collected allele and haplotype frequencies, are the first step in establishing a national reference X-STR database based on 8 X-STR loci.

Abstract
Background Haplotype analysis of closely associated markers has proven to be a powerful tool in kinship analysis, especially when short tandem repeats (STR) fail to resolve uncertainty in relationship analysis. STR located on the X chromosome show stronger linkage disequilibrium compared with autosomal STR. So, it is necessary to estimate the haplotype frequencies directly from population studies as linkage disequilibrium is population-specific. Methodology and Findings Twenty-six X-STR loci including six clusters of linked markers DXS6807-DXS8378-DXS9902(Xp22), DXS7132-DXS10079-DXS10074-DXS10075-DXS981 (Xq12), DXS6801-DXS6809-DXS6789-DXS6799(Xq21), DXS7424-DXS101-DXS7133(Xq22), DXS6804-GATA172D05(Xq23), DXS8377-DXS7423 (Xq28) and the loci DXS6800, DXS6803, DXS9898, GATA165B12, DXS6854, HPRTB and GATA31E08 were typed in four nationality (Han, Uigur, Kazakh and Mongol) samples from China (n = 1522, 876 males and 646 females). Allele and haplotype frequency as well as linkage disequilibrium data for kinship calculation were observed. The allele frequency distribution among different populations was compared. A total of 5–20 alleles for each locus were observed and altogether 289 alleles for all the selected loci were found. Allele frequency distribution for most X-STR loci is different in different populations. A total of 876 male samples were investigated by haplotype analysis and for linkage disequilibrium. A total of 89, 703, 335, 147, 39 and 63 haplotypes were observed. Haplotype diversity was 0.9584, 0.9994, 0.9935, 0.9736, 0.9427 and 0.9571 for cluster I, II, III, IV, V and VI, respectively. Eighty-two percent of the haplotype of cluster IIwas found only once. And 94% of the haplotype of cluster III show a frequency of <1%. Conclusions These results indicate that allele frequency distribution for most X-STR loci is population-specific and haplotypes of six clusters provide a powerful tool for kinship testing and relationship investigation. So it is necessary to obtain allele frequency and haplotypes data of the linked loci for forensic application.

Abstract
To develop a multiplex polymerase chain reaction (PCR) system with 12 X-chromosomal short-tandem repeat (X-STR) loci and to investigate their polymorphism and linkage and/or independence, the 12 loci (DXS6807, DXS8378, DXS9902, DXS6800, DXS6803, DXS6799, DXS6804, GATA172D05, DXS6854, HPRTB, DXS8377, and DXS7423) were simultaneously analyzed in 1,005 unrelated individuals (574 males and 431 females) from Guangdong Han individuals and Kazakh populations living in China. The allele frequencies and mutation rates were investigated. Allele frequency distribution among different populations was compared. Haplotypes of linkage disequilibrium markers (DXS6807-DXS8378-DXS9902) and linked markers (DXS6804-GATA172D05 and DXS8377-DXS7423) were also reported. A total of 117 alleles, ranging from five to 20 for each locus, were observed in our selected populations. Eight cases with mutation of the selected loci were detected in 9,480 meioses. Pairwise comparisons of allele frequencies distribution showed statistically significant differences at most loci among different populations. Haplotype diversity of linked markers was 0.9404-0.9694. The results indicated that this multiplex system is very useful for forensic analysis and may be complementarities for X-12 kits or X-8 kits in forensic case.

Abstract
X chromosome STR (X-STR) polymorphisms are a useful tool in the fields of human population genetics and personal identification and are quite informative in the investigation of complex kinship or deficiency cases, especially where it is necessary to determine relationships with second-generation offspring in which the same X chromosome may have been inherited. We investigated eight X-STR systems using the Mentype Argus X-8 kit and further developed decaplex PCR for the DXS10148, DXS10161, DXS10160, DXS10159, DXS10079, DXS10075, DXS6799, DXS10102, DXS10106, and DXS10146 loci with the aim of constructing closely linked groups on the X chromosome. The studied population comprised 569 Japanese individuals (390 males and 179 females). Heterozygosity among the present 18 X-STRs showed a distribution of from 54.2% to 90.5%. We constructed six closely linked groups, each comprising three to five X-STRs: DXS10148- DXS10135-DXS8378, DXS10161- DXS10160-DXS10159, DXS7132-DXS10079-DXS10074-DXS10075-DXS981, DXS6809-DXS6789-DXS6799, DXS10102-HPRTB-DXS10101-DXS10106, and DXS8377-DXS10146-DXS10134-DXS7423. The forensic utility of these groups as haplotypes was then evaluated. Haplotype diversity values showed a distribution of from 0.9699 to 0.9959. Analysis of the present closely linked haplotypes will contribute to solving complex kinship cases involving X chromosome inheritance.
