China has repeatedly been the subject of genetic studies to elucidate its prehistoric and historic demography. While some studies reported a genetic distinction between Northern and Southern Han Chinese, others showed a more clinal picture of small differences within China. Here, we investigated the distribution of Y chromosome variation along administrative as well as ethnic divisions in the mainland territory of the People's Republic of China, including 28 administrative regions and 19 recognized Chinese nationalities, to assess the impact of recent demographic processes...

By using the recently introduced 6-dye Yfiler(®) Plus multiplex, we analyzed 462 males belonging to 20 ethnic groups from four eastern African countries (Eritrea, Ethiopia, Djibouti and Kenya). Through a Y-STR sequence analysis, combined with 62 SNP-based haplogroup information, we were able to classify observed microvariant alleles at four Y-STR loci as either monophyletic (DYF387S1 and DYS458) or recurrent (DYS449 and DYS627). We found evidence of non-allelic gene conversion among paralogous STRs of the two-copy locus DYF387S1...

Y-chromosomal haplogroups are sets of ancestrally related paternal lineages, traditionally assigned by the use of Y-chromosomal single nucleotide polymorphism (Y-SNP) markers. An increasingly popular and a less labor-intensive alternative approach has been Y-chromosomal haplogroup assignment based on already available Y-STR data using a variety of different algorithms. In the present study, such in silico haplogroup assignments were made based on 23-loci Y-STR data for 100 unrelated male individuals from the Tuzla Canton, Bosnia and Herzegovina (B&H) using the following four different algorithms: Whit Athey's Haplogroup Predictor, Jim Cullen's World Haplogroup & Haplogroup-I Subclade Predictor, Vadim Urasin's YPredictor and the NevGen Y-DNA Haplogroup Predictor...

In this paper, we demonstrate a rapid analysis procedure for use with a small set of rapidly mutating Y chromosomal short tandem repeat (Y-STR) loci that combines both rapid polymerase chain reaction (PCR) and microfluidic separation elements. The procedure involves a high-speed polymerase and a rapid cycling protocol to permit PCR amplification in 16 min. The resultant amplified sample is next analysed using a short 1.8-cm microfluidic electrophoresis system that permits a four-locus Y-STR genotype to be produced in 80 s...

In this study, we compared two recently released commercial Y-chromosomal short tandem repeat (Y-STR) kits: the PowerPlex Y23 System (PPY23) and Yfiler® Plus PCR amplification kit (YPlus). We performed validation studies, including sensitivity, tolerance to PCR inhibitors, and mixture analysis, and a population genetics study using 306 unrelated South Korean males. PPY23 and YPlus showed similar sensitivity, but PPY23 showed higher tolerance to humic acid than YPlus. Furthermore, the detection rate of unique minor alleles called from male/male mixtures was higher for PPY23 than for YPlus...

In forensic science and human genetics, Y-chromosomal short tandem repeats (Y-STRs) have been used as very useful markers. Recently, more Y-STR markers have been analyzed to enhance the resolution power in haplotype analysis, and 13 rapidly mutating (RM) Y-STRs have been suggested as revolutionary tools that can widen Y-chromosomal application from paternal lineage differentiation to male individualization. We have constructed two multiplex PCR sets for the amplification of 13 RM Y-STRs, which yield small-sized amplicons (<400bp) and a more balanced PCR efficiency with minimum PCR cycling...

The aim of the study was to perform the genetic identification of a human cranium from a Second World War gravesite in Slovenia and find out if it belonged to the mother of a woman used as a family reference. Both genetic and anthropological examinations were carried out. The genetic examination was performed on 2 molars and petrous bone. Prior to DNA isolation 0.5 g of tooth and bone powder was decalcified. The DNA was purified in a Biorobot EZ1 (Qiagen) device. The nuclear DNA of the samples was quantified and short tandem repeat (STR) typing performed using two different autosomal and Y-STR kits...

Rapidly Mutating Y-STRs (RM Y-STRs) were recently introduced in forensics in order to increase the differentiation of Y-chromosomal profiles even in case of close relatives. We estimate RM Y-STRs mutation rates and their power to discriminate between related individuals by using samples extracted from a wide set of paternal pedigrees and by comparing RM Y-STRs results with those obtained from the Y-filer set. In addition, we tested the ability of RM Y-STRs to discriminate between unrelated individuals carrying the same Y-filer haplotype, using the haplogroup R-M269 (reportedly characterised by a strong resemblance in Y-STR profiles) as a case study...

BACKGROUND: Although the primary objective of forensic DNA analyses of unidentified human remains is positive identification, cases involving historical or archaeological skeletal remains often lack reference samples for comparison. Massively parallel sequencing (MPS) offers an opportunity to provide biometric data in such cases, and these cases provide valuable data on the feasibility of applying MPS for characterization of modern forensic casework samples. In this study, MPS was used to characterize 140-year-old human skeletal remains discovered at a historical site in Deadwood, South Dakota, United States...
