Y STR haplotype diversity in central Indian population

Abstract

Aims: Seventeen Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y-GATA-H4) were analysed in 173 males belonging to the central Indian population with the aim of studying genetic diversity and adding to the population database. Methods: Multiplexed PCR amplifications of the 17 Y STR loci were performed using AmpFlSTR® Yfiler® Kit. Amplified products were genotyped using a multi capillary electrophoresis with POP-4 polymer in ABI Prism 3100 Genetic Analyzer. Population genetic diversity and allele frequencies were calculated. The haplotype data obtained in the study was compared with the Y-STR haplotypes reference database (YHRD, http://www.yhrd.org) and with previously published population data using the AMOVA tool and visualised in two-dimensional multidimensional scaling (MDS) plots. Results: A total of 147 haplotypes were observed, out of which 125 were unique. Haplotype diversity and discriminating capacity were found to be 0.9979 and 0.8497, respectively. The gene diversity at the loci ranged from 0.398–0.785. Genotype diversity at the locus DYS385a/b was found to be 0.869. Conclusions: The population of central India was found to be significantly different (p < 0.05) when compared with populations from other parts of the Indian sub-continent and the population data of other countries. The population data generated in this study are useful for forensic, anthropological and demographic studies.
