“…These review articles provide up-to-date information and overviews of the state of MPS STR sequencing and validation in forensic genomics. MPS STR technology has also been applied to paternity testing. , Silva et al tested 29 trios (mother–child–father) using an autosomal and Y-STR MPS commercial kit resulting in an increase in the paternity index values as compared to capillary electrophoresis length-based approaches. The authors also report allele inconsistencies (mutations) between child and parents may be resolved with MPS by assessing the core repeat and flanking region sequences, thus resulting in increased resolution for the trios/families tested…”

“…The large-scale performances and functional tests had been widely validated for the ForenSeq™ DNA Signature Prep Kit, the DNA Primer Set A (DPMA, 152 loci totally: 27 common, forensic autosomal STRs, 24 Y-STRs, 7 X-STRs, and 94 identity informative SNPs) and the DNA Primer Set B (in total 230 loci: DMPA plus 22 phenotypic informative SNPs and 56 biogeographical ancestry SNPs), which also include robustness, reproducibility, species specificity, consistency and sensitivity of detection [40][41][42][43][44][45][46][47]. In addition, the applicability of the DNA Signature Prep Kit had been evaluated and verified on challenging samples, DNA mixture, degradative DNA [48][49][50], formalin-fixed paraffin-embedded tissues [49,51], and remains of skeletons and bones [48,[52][53][54], to extend the applications for forensic sciences [55][56][57][58][59][60][61][62][63][64][65][66][67][68]. Hence, on the basis of the sufficient validations of the stability and homogeneity, more essential data of worldwide populations are needed urgently at present to improve the standard experimental procedures, promote the efficiencies of MPS-based system, and strengthen and unify the contacts between capillary electrophoresis-based (CE-based) and MPS-based data for the basic and extended applications of forensic sciences and others.As the aborigines in Hainan island where was the entrances to East Asia (either the southern entrance from Indo-China peninsula or the northern entrance from Central Asia) [12,[69][70][71], Hainan...…”

Due to the formation of the Qiongzhou Strait by climate change and marine transition, Hainan island isolated from the mainland southern China during the Last Glacial Maximum. Hainan island, located at the southernmost part of China and separated from the Leizhou Peninsula by the Qiongzhou Strait, laid on one of the modern human northward migration routes from Southeast Asia to East Asia. The Hlai-language speaking Li minority, the second largest population after Han Chinese in Hainan island, is the direct descendants of the initial migrants in Hainan island and has unique ethnic properties and derived characteristics, however, the forensic associated studies on Hainan Li population are still insufficient.Hence, 136 Hainan Li individuals were genotyped in this study using the MPS-based ForenSeq™ DNA Signature Prep Kit (DNA Primer Set A) to characterize the forensic genetic polymorphism landscape, and DNA profiles were obtained from 152 different molecular genetic markers (27 autosomal STRs, 24 Y-STRs, 7 X-STRs, and 94 iiSNPs). A total of 419 distinct length variants and 586 repeat sequence sub-variants, with 31 novel alleles (at 17 loci), were identified across the 58 STR loci from the DNA profiles of Hainan Li population. We evaluated the forensic characteristics and efficiencies of DAPA, it demonstrated that the STRs and iiSNPs in DAPA were highly polymorphic in Hainan Li population and could be employed in forensic applications. In addition, we set up three Datasets, which included the genetic data of (Ⅰ). iiSNPs (27 populations, 2640 individuals), (Ⅱ). Y-STRs (42 populations, 8281 individuals), and (Ⅲ). Yhaplogroups (123 populations, 4837 individuals) along with the population ancestries and language families, to perform population genetic analyses separately from different perspectives.In conclusion, the phylogenetic analyses indicated that Hainan Li, with a southern East Asia origin and Tai-Kadai language-speaking language, is an isolated population relatively. But the genetic pool of Hainan Li influenced by the limited gene flows from other Tai-Kadai populations and Hainan populations. Furthermore, the establishment of isolated population models will be beneficial to clarify the exquisite population structures and develop specific genetic markers for subpopulations in forensic genetic fields. Signature Prep Kit; Massively parallel sequencing. mass landings of the Han (since BC 214 in Qin Dynasty) and Lingao people (about BC 500 during the Spring and Autumn period) compressed the living space of Hainan Li, making Li from the north to the south of Hainan island [1,2,9,29,30]. (Nowadays, the main distributions of Hainan Li minority are shown in Fig. 1C.) In all ages, ever since the primordial settlements in Hainan island, Hlai language was the dominant language for the original migrants and their descendants, and the intangible cultural and spiritual heritages within Hainan Li were preserved by oral transmission without ancient writings to hand down. Hlai, which is one important branch of the Tai-Kadai languag...
