Abstract
Sequence polymorphisms were characterized at 27 autosomal STRs (A-STRs), 7 X chromosomal STRs (X-STRs), and 24 Y chromosomal STRs (Y-STRs) in 635 Northern Han Chinese with the ForenSeq DNA Signature Prep Kit on the MiSeq FGx Forensic Genomics System. Since repeat region (RR) and flanking region (FR) variation can be detected by massively parallel sequencing (MPS), the increase in the number of unique alleles and the average of gene diversity was 78.18% and 3.51% between sequence and length, respectively. A total of 74 novel RR variants were identified at 33 STRs compared with STRSeq and previous studies, and 13 FR variants (rs1770275883, rs2053373277, rs2082557941, rs1925525766, rs1926380862, rs1569322793, rs2051848492, rs2051848696, rs2016239814, rs2053269960, rs2044518192, rs2044536444, and rs2089968964) were first submitted to dbSNP. Also, 99.94% of alleles were concordant between the ForenSeq DNA Signature Prep Kit and commercial CE kits. Discordance resulted from the low performance at D22S1045 and occasionally at DYS392, flanking region deletions at D7S820 and DXS10074, and the strict alignment algorithm at DXS7132. Null alleles at DYS505 and DYS448 and multialleles at DYS387S1a/b, DYS385a/b, DYS448, DYS505, DXS7132, and HPRTB were validated with other MPS and CE kits. Thus, a high-resolution sequence-based (SB) and length-based (LB) allele frequencies dataset from Northern Han Chinese has been established already. As expected, forensic parameters increased significantly on combined power of discrimination (PD) and combined power of exclusion (PE) at A-STRs, mildly on combined PD and combined mean exclusion chance (MEC) at X-STRs, and barely on discrimination capacity (DC) at Y-STRs. Additionally, MiSeq FGx quality metrics and MPS performance were evaluated in this study, which presented the high-quality of the dataset at 20 consecutive runs, such as ≥ 60% bases with a quality score of 20 or higher (%≥ Q20), > 60% of effective reads, > 2000 × of depth of coverage (DoC), ≥ 60% of allele coverage ratio (ACR) or heterozygote balance, ≥ 70% of inter-locus balance, and ≤ 0.4 of the absolute value of observed minus expected heterozygosity (|Hexp - Hobs|). In conclusion, MiSeq FGx can help us generate a high-resolution and high-quality dataset for human identification and population genetic studies.

Sequence Read Depth Analysis of a Monophyletic Cluster of Y Chromosomes Characterized by Structural Rearrangements in the AZFc Region Resulting in DYS448 Deletion and DYF387S1 Duplication.

Abstract
The azoospermia factor c region (AZFc), located in the long arm of the human Y chromosome, is frequently involved in chromosome rearrangements, mainly due to non-allelic homologous recombination events that occur between the nearly identical sequences (amplicon) that comprises it. These rearrangements may have major phenotypic effects like spermatogenic failure or other pathologies linked to male infertility. Moreover, they may also be relevant in forensic genetics, since some of the Y chromosome short tandem repeats (Y-STRs) commonly used in forensic analysis are located in amplicons or in inter-amplicon sequences of the AZFc. In a previous study, we identified four phylogenetically related samples with a null allele at DYS448 and a tetrallelic pattern at DYF387S1, two Y-STRs located in the AZFc. Through NGS read depth analysis, we found that the unusual Y-STR pattern may be due to a 1.6 Mb deletion arising concurrently or after a 3.5 Mb duplication event. The observed large genomic rearrangement results in copy number reduction for the RBMY gene family as well as duplication of other AZFc genes. Based on the diversity of 16 additional Y-STRs, we estimated that the duplication/deletion event occurred at least twenty generations ago, suggesting that it has not been affected by negative selection.

Ethnic fragmentation and degree of urbanization strongly affect the discrimination power of Y-STR haplotypes in central Sahel. Forensic Sci Int Genet 2020; 49:102374. [PMID: 32890883 DOI: 10.1016/j.fsigen.2020.102374] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 07/06/2020] [Accepted: 08/16/2020] [Indexed: 10/23/2022]
Abstract
Y chromosome short tandem repeats (Y-STRs) are commonly used to identify male lineages for investigative and judicial purposes and could represent the only source of male-specific genetic information from unbalanced female-male mixtures. The Yfiler Plus multiplex, which includes twenty conventional and seven rapidly-mutating Y-STRs, represents the most discriminating patrilineal system commercially available to date. Over the past five years, this multiplex has been used to analyze several Eurasian populations, with a reported discrimination capacity (DC) approaching or corresponding to the highest possible value. However, despite the inclusion of rapidly mutating Y-STRs, extensive haplotype sharing was still reported for some African populations due to a number of different factors affecting the effective population size. In the present study, we analyzed 27 Y-STRs included in the Yfiler Plus multiplex and 82 Y-SNPs in central Sahel (northern Cameroon and western Chad), an African region characterized by a strong ethnic fragmentation and linguistic diversity. We evaluated the effects of population sub-structuring on genetic diversity by stratifying a sample composed of 431 males according to their ethnicity (44 different ethnic groups) and urbanization degree (four villages and four towns). Overall, we observed a low discrimination capacity (DC = 0.90), with 71 subjects (16.5 %) sharing 27 Y-STR haplotypes. Haplotype sharing was essentially limited to subjects with the same binary haplogroup, coming from the same location and belonging to the same ethnic group. Haplotype sharing was much higher in rural areas (average DC = 0.83) than urban settlements (average DC = 0.96) with a significant correlation between DC and census size (r = 0.89; p = 0.003). Notably, we found that genetic differentiation between villages from the same country (ΦST = 0.14) largely exceeded that found among countries (ΦST = 0.02). These findings have important implications for the choice of the appropriate reference population database to evaluate the statistical relevance of forensic Y-haplotype matches.
