The Y-STR landscape of coastal southeastern Han: Forensic characteristics, haplotype analyses, mutation rates, and population genetics. Electrophoresis 2021; 42:1578-1593.

Abstract
The Y-STR landscape of Coastal Southeastern Han (CSEH) living in Chinese southeast areas (including Guangdong, Fujian, and Zhejiang provinces) is still unclear. We investigated 62 Y-STR markers in a reasonably large number of 1021 unrelated males and 1027 DNA-confirmed father-son pairs to broaden the genetic backgrounds of CSEH. In total, 85 null alleles, 121 off-ladder alleles, and 95 copy number variants were observed, and 1012 distinct haplotypes were determined with the overall HD and DC values of 0.999974 and 0.9912. We observed 369 mutations in 76 099 meiotic transfers, and the average estimated Y-STR mutation rate was 4.85 × 10-3 (95% CI, 4.4 × 10-3 -5.4 × 10-3 ). The Spearman correlation analyses indicated that GD values (R2 = 0.6548) and average allele sizes (R2 = 0.5989) have positive correlations with Y-STR mutation rates. Our RM Y-STR set including 8 candidate RM Y-STRs, of which DYS534, DYS630, and DYS713 are new candidates in CSEH, distinguished 18.52% of father-son pairs. This study also clarified the population structures of CSEH which isolated in population-mixed South China relatively. The strategy, SM Y-STRs for familial searching and RM Y-STRs for individual identification regionally, could be applicable based on enough knowledge of the Y-STR mutability of different populations.

Insights From Y-STRs: Forensic Characteristics, Genetic Affinities, and Linguistic Classifications of Guangdong Hakka and She Groups. Front Genet 2021; 12:676917. [PMID: 34108995 PMCID: PMC8181459 DOI: 10.3389/fgene.2021.676917] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2021] [Accepted: 04/06/2021] [Indexed: 12/02/2022] Open
Abstract
Guangdong province is situated in the south of China with a population size of 113.46 million. Hakka is officially recognized as a branch of Han Chinese, and She is the official minority group in mainland China. There are approximately 25 million Hakka people who mainly live in the East and North regions of China, while there are only 0.7 million She people. The genetic characterization and forensic parameters of these two groups are poorly defined (She) or still need to be explored (Hakka). In this study, we have genotyped 475 unrelated Guangdong males (260 Hakka and 215 She) with Promega PowerPlex® Y23 System. A total of 176 and 155 different alleles were observed across all 23 Y-STRs for Guangdong Hakka (with a range of allele frequencies from 0.0038 to 0.7423) and Guangdong She (0.0047–0.8605), respectively. The gene diversity ranged from 0.4877 to 0.9671 (Guangdong Hakka) and 0.3277–0.9526 (Guangdong She), while the haplotype diversities were 0.9994 and 0.9939 for Guangdong Hakka and Guangdong She, with discrimination capacity values of 0.8885 and 0.5674, respectively. With reference to geographical and linguistic scales, the phylogenetic analyses showed us that Guangdong Hakka has a close relationship with Southern Han, and the genetic pool of Guangdong Hakka was influenced by surrounding Han populations. The predominant haplogroups of the Guangdong She group were O2-M122 and O2a2a1a2-M7, while Guangdong She clustered with other Tibeto-Burman language-speaking populations (Guizhou Tujia and Hunan Tujia), which shows us that the Guangdong She group is one of the branches of Tibeto-Burman populations and the Huonie dialect of She languages may be a branch of Tibeto-Burman language families.

Mol Genet Genomic Med 2020; 8:e1338. [PMID: 32537948 PMCID: PMC7434754 DOI: 10.1002/mgg3.1338] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Accepted: 05/11/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Y-chromosomal short tandem repeats (Y-STRs) have been certified to be the serviceable markers for some paternity cases in the last few years. METHODS We presented the gene diversity, haplotypic diversity, and forensic statistical parameters of 340 unrelated Uighur males from Kashi region based on the 27 Y-STRs. Genomic DNA was extracted from bloodstain samples using the Chelex-100 method and amplified by Yfiler® Plus PCR Amplification kit. RESULTS Gene diversity values on the 27 Y-STRs ranged from 0.4749 (at DYS437 locus) to 0.9416 (at DYS385a,b loci). According to forensic parameters of the 27 Y-STR loci, 295 disparate haplotypes were acquired, 258 of which were unique. The haplotypic diversities and discrimination capacities at Yfiler plus 27 loci, Yfiler 17 loci, extended 11 loci, and minimal 9 loci were 0.9990 and 0.8676; 0.9961 and 0.6912; 0.9952 and 0.5941; and 0.9919 and 0.5676, respectively. Multidimensional scaling plot and neighbor-joining tree between the studied Uighur group and 17 reference populations were conducted, and the obtained results indicated the Kashi Uighur group had the closer genetic relationships with Uighur groups living in different regions. CONCLUSION To sum up, the present study may provide valuable population data and background information of Kashi Uighur group.
