Genetic polymorphisms of twelve X-STRs of the investigator Argus X-12 kit and additional six X-STR centromere region loci in an Egyptian population sample

Recently, many researchers have focused on analysis of different X-chromosomal STRs as they bear the potential to efficiently complement the analysis of autosomal and Y-chromosomal STRs in solving special complex kinship deficiency cases. In the current study we examined a sample of 250 unrelated Egyptian males with the Investigator Argus X-12 kit (Qiagen GmbH, Hilden, Germany) which detects 12 X-STR markers distributed over the entire X-chromosome as four closely linked clusters. Microvariant off ladder alleles as well as null alleles have been detected in some loci. Furthermore, discordant results were observed between the Investigator Argus X-12 and the Mentype^® Argus X-8 kits (Biotype AG, Dresden, Germany). New primers were designed for loci DXS10101, DXS10146 and DXS10148 to correct the allele drop outs observed in these loci with the Investigator Argus X-12 kit. Additionally, DNA sequence analysis revealed the polymorphisms responsible for the allele drop outs. Furthermore, six additional X-STRs (DXS10161, DXS10159, DXS10162, DXS10163, DXS10164 and DXS10165) located in the centromere region at Xp11.21–Xq11.1 were examined in a single multiplex reaction. Allele and haplotype frequencies as well as different forensic statistical parameters of the 18 X-STR loci tested indicated that they are highly informative in different forensic applications in the Egyptian population. However, some modifications still need to be performed on the Investigator Argus X-12 kit before its use in forensic casework is validated.     

A reference database of forensic autosomal and gonosomal STR markers in the Tigray population of Ethiopia

Allele frequencies of 21 autosomal STR markers (AmpF/STR GlobalFiler) and haplotype frequencies of 27 Y- and 12 X-STR markers (AmpF/STR YFiler Plus and Investigator Argus X-12, respectively) were investigated in the Tigray population of Ethiopia, representing the main population group in the Tigray regional state of Ethiopia and neighboring Eritrea. For autosomal STR allele frequencies, the average random match probability in the Tigray sample was 2.1 × 10^-27. The average locus by locus F_ST distance calculated comparing autosomal STR allele frequencies from Tigray and from a broad regional reference dataset currently available for the Horn of Africa was 0.003. The Tigray male sample displayed high Y-STR diversity, with complete individualization of haplotypes using the AmpF/STR YFiler Plus panel. Analysis of molecular variance did not detect significant heterogeneity between Y-STR haplotypes observed in the present study and those previously reported in the literature for other Tigray population samples from Ethiopia and Eritrea. Study of the X-STR landscape in Tigray evidenced several distinctive features including: the molecular characterization of a novel null allele at locus DXS10146 with frequency > 1%; allele dependency between loci within linkage groups I and III; significant differences in haplotype distribution compared to other Horn of Africa populations, that should be taken into account in kinship analysis. The collected data can be used as a reference STR database by local forensic genetics services and in genetic identification procedures of victims of human trafficking in the Mediterranean Sea, which frequently involve individuals originating from the Horn of Africa.     

Analysis of 12 X-chromosomal markers in the population of central Croatia

Investigator® Argus X-12 Kit is a commercially available set that allows simultaneous PCR amplification of 12 X-STR markers belonging to four linkage groups (LG). To assess the forensic efficiency of these markers for the population of central Croatia and consequent applicability in routine forensic casework, DNA from 200 blood samples of unrelated donors (100 female and 100 male) was amplified by Investigator® Argus X-12 Kit and analyzed by capillary electrophoresis. Statistical computations based on allele and haplotype frequencies for LG1 – LG4 were performed using Arlequin 3.5 software and on-line tool available at ChrX-STR.org. In female samples, all X-STR markers were in Hardy-Weinberg equilibrium (HWE). The most informative marker for central Croatia population was DXS10135 with polymorphism information content (PIC) 0.9296. The least polymorphic locus was DXS8378 (PIC = 0.6363). Power of discrimination (PD) varied from 0.6968 to 0.9336 in male and from 0.8476 to 0.9916 in female samples. Combined PD exceeded 0.999999999 in both men and women. In male samples, linkage disequilibrium (LD) test revealed significant association (P = 0.0000) of one marker pair in LG4 and two marker pairs in LG3. Portion of observed haplotypes in the number of possible haplotypes varied from 2.86% to 7.47% across all LGs. LG1 was the most informative with haplotype diversity (H) 0.9972. High PD of all analyzed markers exhibited for central Croatia population confirms suitability of Investigator® Argus X-12 for forensic pertinence. Moreover, results of this study will be included in establishing a national reference X-STR database based on 12 X-STR loci, which is necessary for the correct interpretation of the forensic casework results.     

Development of 11 X-STR loci typing system and genetic analysis in Tibetan and Northern Han populations from China

X-chromosomal short tandem repeats (X-STRs) loci are used for forensic practice in recent years which play increasingly important roles in some complex kinship cases. In this paper, a new multiplex polymerase chain reaction (PCR) system which can simultaneously analyze 11 X-STR markers (DXS8378, DXS6795, DXS7132, DXS6803, DXS9898, DXS6801, DXS7133, GATA165B12, HPRTB, DXS8377 and DXS7423) was developed. The samples of 1,605 (742 males and 863 females) unrelated individuals from Tibetan and Northern Han population were successfully analyzed using this multiplex system. A total of 103 alleles for all the loci were observed. Hardy–Weinberg equilibrium tests demonstrated no significant deviation from expected values (P > 0.05) for all of the 11 X-STR loci in the two studied populations. Polymorphism information contents of the loci were 0.3864–0.9013, and powers of discrimination in females of the loci were 0.6317–0.9845. There were no statistically significant differences between Tibetan and Northern Han populations in allele distribution of the 11 X-STR loci, in line with analysis of molecular variance (AMOVA) results. Our work indicates that this multiplex system is useful for forensic analysis for the two populations in China.     

A genetic overview of Atlantic coastal populations from Europe and North-West Africa based on a 17 X-STR panel

The forensic use of X-STRs requires the creation of allele and haplotype frequency databases in the populations where they are going to be used. Recently, an updated Spanish allele and haplotype frequency database for the new 17 X-STR panel has been created, being the only database available up to now for this new multiplex. In order to broaden the forensic applicability of the 17 X-STR panel, 513 individuals from four different populations located on the Atlantic Coast of Europe and North–West Africa have been studied, i.e. Brittany (France), Ireland, northern Portugal, and Casablanca (Morocco). Allele and haplotype frequency databases, as well as parameters of forensic interest for these populations are presented. The obtained results showed that the 17 X-STR panel constitutes a highly discriminative tool for forensic identification and kinship testing in the studied populations. Furthermore, we aimed to study if these populations located on the Atlantic coast actually share alike allele and haplotype frequency distributions since they have experienced genetic exchanges throughout history. This would allow creating larger forensic databases that include several genetically similar populations for its use in forensic casework. For this purpose, pairwise F_ST genetic distances between the analyzed populations and others from the Atlantic Coast previously studied with the 17 X-STR panel or the ten coincident markers included in the decaplex of the GHEP-ISFG were estimated. Our results suggest that certain nearby populations located on the European Atlantic coast could have underwent episodes of genetic interchange as they have not shown statistically significant differentiation between them. However, the population of Casablanca showed significant differentiation with the majority of the European populations. Likewise, the autochthonous Basque Country and Brittany populations have shown distinctive allele frequency distributions between them. Therefore, these findings seem to support that the use of independent allele and haplotype frequency databases for each population instead of a global database would be more appropriate for forensic purposes.     

Forensic parameters of 19 X-STR polymorphisms in two Chinese populations

Application of X-STRs as complements of autosomal STR application in the forensic genetics has become a tendency for kinship testing, especially in deficiency paternity cases. Recently, a novel kit of 19 X-STR loci was developed, which permitted the analysis of 19 STR in the same PCR reaction, and these markers can be clustered into seven groups for the physical linkage. The objective of this study was to evaluate the allele and haplotype diversity of 19 X-STR loci in the Uygur (n = 220) and Tibetan nationality (n = 270) and to estimate the usefulness for complex kinship analysis. In the Tibetan and Uygur populations, a total of alleles of all loci were 188 and 212, with the allele frequencies ranged from 0.0037 to 0.5593 and from 0.0045 to 0.5409, respectively. Compared with previous studies, DXS10135 was the most polymorphic locus in the two population groups, whereas the least variant locus was DXS10164 in the Uygur population and DXS7423 in the Tibetan nationality. Haplotype diversity obtained in this investigation was greater than 0.9 across all LGs. This study indicated the new kit could be used as a supplementary tool in kinship testing in China. In addition, the data sets can be used as supplementary national X-STR references to enlarge the database.

     

Resolving the recombination pattern of 38 X-STRs from Chinese Han three-generation pedigrees

X-chromosomal markers have been proved as a useful tool for solving complex kinship cases due to its sex-linked inheriting feature. Among these markers, tightly linked X-STR clusters forming haplotypes are highly informative. The analysis of the haplotypes requires determination of linkage disequilibrium. In this study, genetic linkage, recombination fractions and mutation rates of 38 X-STR loci in 177 three-generation pedigrees were investigated. Genetic linkage analysis and calculation of recombination fractions were performed within each pair of markers and clusters. Then mutation rates were calculated. The results showed that, a) 22 recombination events happened within the tightly linked X-STR clusters, which span<1.0 Mb; b) significantly linked marker pairs were observed with the LOD (logarithm of the odds) scores > 2.0 (2.0104 to 54.8316); c) the average mutation rate of the 38 X-STR loci was 1.32 × 10⁻³ per meiosis in the Chinese Han population, with DXS10135 and DXS8377 presenting notably high mutation rate (6.5 × 10⁻³). Our results confirmed that meiotic recombination was not a simple function of physical distance, so that whether recombination occurred at the closely clustered X-STRs or not should be assumed cautiously considering the stability of haplotypes in inheritance process for kinship analysis. This study supplemented the existing database and laid an experimental foundation for the future study on genetic characteristics, recombination, and mutation of the X-STRs.     

Population and forensic data for three sets of forensic genetic markers in four ethnic groups from Iran: Persians,Lurs, Kurds and Azeris

A total of 255 individuals (Persians, Lurs, Kurds and Azeris) from Iran were typed for three sets of forensic genetic markers with the NGM SElect™, DIPplex^® and Argus X-12 kits. Statistically significant deviations (P ≤ 0.002) from Hardy–Weinberg expectations were observed for the insertion-deletion markers HLD97 and HLD93 after Holm–Šidák correction. Statistically significant (P < 0.05) levels of linkage disequilibrium were observed between markers within two of the four studied X-chromosomal linkage groups. AMOVA analyses of the three sets of markers did not show population structure when the individuals were grouped according to their ethnic group. The Iranian population grouped closely to populations living geographically near to Iran based on pairwise F_ST distances. The matching probabilities ranged from 1 in 3.2 × 10⁷ males by using haplotype frequencies of four X-chromosomal haplogroups to 1 in 3.4 × 10²¹ individuals for the 16 autosomal STRs.     

Genetic characterization of Guinea-Bissau using a 12 X-chromosomal STR system: Inferences from a multiethnic population

A male West African sample from Guinea-Bissau (West-African coast) was genetically analyzed using 12 X chromosomal short tandem repeats that are grouped into four haplotype groups. Linkage disequilibrium was tested (p ≤ 0.0008) and association was detected for the majority of markers in three out of the four studied haplotype clusters. The sample of 332 unrelated individuals analyzed in this study belonged to several recognized ethnic groups (n = 18) which were used to evaluate the genetic variation of Guinea-Bissau’s population. Pairwise genetic distances (F_ST) did not reveal significant differences among the majority of groups. An additional 110 samples from other countries also belonging to West Africa were as well compared with the sample of Guinea-Bissau. No significant differences were found between these two groups of West African individuals, supporting the genetic homogeneity of this region on the X chromosome level. The generation of over 100 DNA West African sequences provided new insights into the repeat sequence structure of some of the present X-STRs. Parameters for forensic evaluation were also calculated for each X-STR, supporting the potential application of these markers in typical kinship scenarios. Also, the high power of discrimination values for samples of female and male origin observed in this study, confirms the usefulness of the present X-STRs in identification analysis.     

Results for five sets of forensic genetic markers studied in a Greek population sample

A population sample of 223 Greek individuals was typed for five sets of forensic genetic markers with the kits NGM SElect™, SNPforID 49plex, DIPplex^®, Argus X-12 and PowerPlex^® Y23. No significant deviation from Hardy–Weinberg expectations was observed for any of the studied markers after Holm–Šidák correction. Statistically significant (P < 0.05) levels of linkage disequilibrium were observed between markers within two of the studied X-chromosome linkage groups. AMOVA analyses of the five sets of markers did not show population structure when the individuals were grouped according to their geographic origin. The Greek population grouped closely to the other European populations measured by F_ST^* distances. The match probability ranged from a value of 1 in 2 × 10⁷ males by using haplotype frequencies of four X-chromosome haplogroups in males to 1 in 1.73 × 10²¹ individuals for 16 autosomal STRs.     

Characteristics of eight X-STR loci for forensic purposes in the Chinese population

X-chromosomal short tandem repeats (ChrX STRs) loci are used for forensic practice in recent years. Considering the unique heredity characteristics of ChrX, recombination and linkage disequilibrium (LD) among ChrX STR loci vary between male and female and different populations as well. However, there is a lack of data for analysis of recombination and linkage disequilibrium on ChrX STR loci in the Chinese population. In this work, a total of 303 unrelated individuals (203 males and 100 females) in the Chinese Han population were analyzed with Mentype Argus X-8 PCR amplification kit (DXS10135-DXS8378, DXS7132-DXS10074, HPRTB-DXS10101, and DXS10134-DXS7423). The recombination and linkage disequilibrium of the eight ChrX STR loci were investigated with HapMap LD plots and software ARLEQUIN 3.1. Allele frequencies of the eight loci and further population forensic genetic parameters were obtained. Our results revealed hotspots for recombination, and there was no obvious evidence for LD among the eight loci in the Chinese population. Our work implied that single locus frequencies rather than haplotype frequencies should be applied for forensic practice in the Chinese population.     

Genetic diversity study on 12 X-STR loci of investigator® Argus X STR kit in Bangladeshi population

The X-chromosome short tandem repeat (STR) loci are of particular interest for solving complex kinship and paternity cases. Here, we report the genetic data from 209 unrelated Bangladeshi individuals (102 males and 107 females) that were genotyped using the 12 X-chromosomal STR markers included in the Investigator® Argus X-12 kit (Qiagen). The 12 X-STR markers are located in four linkage groups (linkage group I: DXS10135, DXS10148, and DXS8378; linkage group II: DXS7132, DXS10079, and DXS10074; linkage group III: DXS10103, HPRTB, and DXS10101; and linkage group IV: DXS10146, DXS10134, and DXS7423). Allelic frequencies of the 12 X-STR loci and haplotype frequencies of the four linkage groups were investigated. No significant difference was observed in the allele frequencies of males and females. Distributions of heterozygosity were observed from 64.5 to 92.5% among the studied 12 X STR loci. DXS10135 and DXS10101 loci were found to be most polymorphic. For all the four linkage groups, the haplotype diversity was found to be greater than 0.986. A total of 95, 73, 66, and 74 haplotypes were observed in linkage groups I, II, III, and IV, respectively. Hardy–Weinberg equilibrium tests showed no significant deviation from expected values for all 12 loci (p > 0.05). The exact test for pairwise linkage disequilibrium for the 12 loci in the male samples did not show any significant linkage disequilibrium except the DXS10103 and DXS10101 loci after the p values were corrected by Bonferroni’s correction for multiple testing (p > 0.05/66). A combined power of discrimination in male and female individuals were 0.999999998159791 and 0.999999999999993, respectively. The combined mean exclusion chance were 0.999997635 in deficiency cases, 0.999999996 in normal trio cases, and 0.999999178 in duo cases. The currently investigated Bangladeshi population showed significant differences when compared with previously reported X-STR data from other 12 populations. The results of the data analysis indicated that all the loci in the Investigator® Argus X 12 kit were fairly informative and might be useful in forensic application and kinship analysis in Bangladeshi population.

     

Forensic efficiency parameters of the Investigator Argus X-12 kit in women from two Mestizo and seven Amerindian populations from Mexico

Allele frequency distribution and statistical parameters of forensic efficiency concerning the Investigator Argus X-12 kit (Qiagen, Hilden, Germany) were determined in a total sample of 641 unrelated Mexican females, including two Mestizo–admixed– populations (n = 309) and seven Amerindian groups (n = 332) from the main regions of the country. Most of the 12 X-STRs were in agreement with Hardy-Weinberg expectations in all nine Mexican populations. The power of discrimination in females (PD) and Median exclusion chance for trios (MEC_T) and duos (MEC_D) of this genetic system based on X-STRs were >99.99%. Although Mexican populations showed significant pairwise differentiation, a closer relationship was evident between Amerindian groups and nearby Mestizos, in agreement with historical records, previous genetic studies, and X-linked inheritance pattern expectations.     

Population genetics of 30 insertion–deletion polymorphisms in two Chinese populations using Qiagen Investigator® DIPplex kit

Insertion–deletion polymorphisms (INDELs) are short length diallelic polymorphisms caused by the insertion or deletion of several bases. INDEL markers can serve as useful supplementary or stand-alone assays for human identification. The Qiagen Investigator^® DIPplex kit multiplexes 30 autosomal INDELs plus amelogenin for forensic use. The objective of this study was to estimate genetic diversity of 30 INDEL markers in the Han (the largest ethnic group of China, n = 565) and She population (almost the smallest ethnic group of China, n = 119), and to evaluate their usefulness in forensic genetics. In the Han and She, the mean observed heterozygosity values were 0.4133 and 0.3896, and the combined matching probability values were 1.80 × 10⁻¹¹ and 3.17 × 10⁻¹¹, respectively. Furthermore, the allele frequencies for each locus were compared with those in other reported Chinese subpopulations, and the forensic efficacy was compared between this kit and in-house developed INDEL assay. This study demonstrates that the Investigator^® DIPplex kit can be used as a supplementary tool for human identity testing in China.     

Analysis of 49 autosomal SNPs in an Iraqi population

Forty-nine of the 52 autosomal single nucleotide polymorphisms (SNPs) in the SNPforID 52plex were typed in 101 unrelated Iraqis living in Denmark. No significant deviation from HWE was found in all but one of the 49 SNP systems and no significant pairwise linkage disequilibrium was observed for any SNP pair. When 18 worldwide populations were compared (including populations in Iraq, Turkey, Israel, Pakistan, India, China, Taiwan, Japan, Siberia, Algeria, Somalia, Uganda, Mozambique, Angola, Nigeria, Denmark, Portugal, Spain), a significant global F_ST value was obtained. All but six F_ST values were statistically significant when pairwise comparisons were performed between the 18 populations. The Iraqi population did not show significant difference from the population in Turkey and it grouped together with other Middle-Eastern populations when a multidimensional scaling plot was drawn based on the pairwise F_ST values. The combined mean match probability and the typical paternity index for trios were 8.3 × 10⁻²⁰ and 259,000, respectively, for the Iraqi population.     

Y-chromosome STR haplotypes in males from Greenland

A total of 272 males from Greenland were typed for 11 Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 with the PowerPlex^® Y System (Promega). A total of 146 different haplotypes were observed and the haplotype diversity was 0.9887. The number of haplotypes seen once was 108 and the most common haplotype was observed in 12 males. A significant F_ST value was observed (F_ST = 0.012, P < 0.00001) when comparing the population of 15 locations in Greenland assigned to 7 groups. The significance could mainly be attributed to the subpopulation of males from Tasiilaq (East of Greenland). The R_ST value was not statistically significant (R_ST = 0.016, P = 0.15).     

FST estimates of 94 populations in China based on STR markers

The proper assessment of DNA evidence in cases of personal identification is a recurring theme in forensics. It is common practice to evaluate the strength of DNA evidence using the likelihood ratio (LR). The accurate use of population allele frequencies is a crucial problem in LR calculation. Allele frequency differences among different populations could be estimated by the F_ST values. Thus, F_ST would also affect LR values by correcting the allele frequencies. In this study, Chinese population allele frequency data were selected from population reports published in Chinese and English journals. The population-specific F_ST values of each population, the overall F_ST values of each province, each region, and the whole country, and the locus-specific F_ST values of different loci were calculated. The LRs using different allele frequencies and different F_ST values were compared based on the combination of simulated genotypes. As a result, the F_ST values of 94 populations, 19 provinces, 7 regions, and the whole country were obtained. The LR was overestimated using allele frequencies of the combined population containing multiple populations rather than using allele frequencies of a population, and the LRs after F_ST correction were lower than those without correction. Conclusively, the correction in conjunction with corresponding F_ST values can make the LRs more accurate and reasonable.     

Analysis of 49 autosomal SNPs in three ethnic groups from Iran: Persians,Lurs and Kurds

A total number of 149 individuals from Iran (Persians, Lurs and Kurds) were analyzed for 49 autosomal SNPs using PCR, SBE and capillary electrophoresis. No deviation from Hardy–Weinberg expectations was observed. One SNP pair (rs1015250–rs251934) showed significant linkage disequilibrium in Kurds. However, this was most likely due to chance. High intrapopulation variability and no significant population structure were observed among the three ethnic groups from Iran. Pairwise F_ST values obtained from the mean numbers of pairwise differences between SNP profiles were calculated for Persians, Lurs, Kurds and eighteen other worldwide populations. For each of the three Iranian ethnic groups, the lowest F_ST values calculated between an Iranian and non-Iranian populations were observed between Iranians and populations in Iraq and Turkey. The three Iranian ethnic groups grouped together with other West Asian populations in the MDS plot drawn from the F_ST values. Statistical parameters of forensic interest calculated for the Iranian ethnic groups showed values of the same order of magnitudes as those obtained for Asians. The mean match probability calculated for the 49 SNPs ranged from 1.7 x 10⁻¹⁸ for Kurds to 1.3 x 10⁻¹⁹ for Persians. Despite the low level of genetic structure observed among Persians, Lurs and Kurds, a single autosomal SNP database should be used with care when extending its forensic application to other Iranian ethnic groups.     

NGMSElect™ and Investigator® Argus X-12 analysis in population samples from Albania,Iraq, Lithuania,Slovenia, and Turkey

The analysis of STRs is the main tool when studying genetic diversity in populations or when addressing individual identification in forensic casework. Population data are needed to establish reference databases that can be used in the forensic context. To that end, this work investigated five population samples from Albania, Iraq, Lithuania, Slovenia, and Turkey. Individuals were typed for 16 autosomal STRs and 12 X-chromosomal STRs using the NGMSElect™ and Investigator^® Argus X-12 kits, respectively. The aim of the study was to characterize the diversity of both STR kits in these population samples and to expand our forensic database.The results showed that all markers were polymorphic in the five populations studied. No haplotype was shared between the males analysed for X-STRs. No statistically significant deviations from Hardy–Weinberg equilibrium were observed for any of the genetic markers included in both the kits. Pairwise LD was only detected in X-STRs between markers located in the same linkage group. Power of discrimination values for males and females and the probability of exclusion in duos and trios were high for the populations in this study.     

Next generation sequencing of SNPs using the HID-Ion AmpliSeq™ Identity Panel on the Ion Torrent PGM™ platform

The HID-Ion AmpliSeq™ Identity Panel (the HID Identity Panel) is designed to detect 124-plex single nucleotide polymorphisms (SNPs) with next generation sequencing (NGS) technology on the Ion Torrent PGM™ platform, including 90 individual identification SNPs (IISNPs) on autosomal chromosomes and 34 lineage informative SNPs (LISNPs) on Y chromosome. In this study, we evaluated performance for the HID Identity Panel to provide a reference for NGS-SNP application, focusing on locus strand balance, locus coverage balance, heterozygote balance, and background signals. Besides, several experiments were carried out to find out improvements and limitations of this panel, including studies of species specificity, repeatability and concordance, sensitivity, mixtures, case-type samples and degraded samples, population genetics and pedigrees following the Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines. In addition, Southern and Northern Chinese Han were investigated to assess applicability of this panel. Results showed this panel led to cross-reactivity with primates to some extent but rarely with non-primate animals. Repeatable and concordant genotypes could be obtained in triplicate with one exception at rs7520386. Full profiles could be obtained from 100 pg input DNA, but the optimal input DNA would be 1 ng–200 pg with 21 initial PCR cycles. A sample with ≥20% minor contributor could be considered as a mixture by the number of homozygotes, and full profiles belonging to minor contributors could be detected between 9:1 and 1:9 mixtures with known reference profiles. Also, this assay could be used for case-type samples and degraded samples. For autosomal SNPs (A-SNPs), F_ST across all 90 loci was not significantly different between Southern and Northern Chinese Han or between male and female samples. All A-SNP loci were independent in Chinese Han population. Except for 18 loci with H_e <0.4, most of the A-SNPs in the HID Identity Panel presented high polymorphisms. Forensic parameters were calculated as >99.999% for combined discrimination power (CDP), 0.999999724 for combined power of exclusion (CPE), 1.390 × 10¹¹ for combined likelihood ratio (CLR) of trios, and 2.361 × 10⁶ for CLR of motherless duos. For Y-SNPs, a total of 8 haplotypes were observed with the value of 0.684 for haplotype diversity. As a whole, the HID Identity Panel is a well-performed, robust, reliable and high informative NGS-SNP assay and it can fully meet requirements for individual identification and paternity testing in forensic science.
