Population genetics data for 22 autosomal STR loci in European, South Asian and African populations using SureID (R) 23comp Human DNA Identification Kit

摘要

Allele frequency data for 22 short tandem repeat loci; D18S1364, D1S1656, D13S325, D5S2800, D9S1122, D4S2366, D3S1744, D12S391, D11S2368, D21S2055, D20S482, D8S1132, D7S3048, D2S441, D19S253, D10S1248, D17S1301, D22-GATA198B05, D16S539, D6S474, D14S1434 and D15S659 from the SureID (R) 23comp Human DNA Identification Kit have been determined for unrelated individuals in European, South Asian and African populations. Deviations from Hardy-Weinberg equilibrium were observed in loci D1S1656 and D195S253 in European; D18S1364, D6S474 and D14S1434 in South Asian; and D9S1122 and D8S1132 in African populations (p-value <0.05). However, after Bonferroni correction no significant deviations were observed (p-value <0.002). The most discriminating loci were D1S1656 and D12S391 for European (PD = 0.977), D21S2055 for South Asian (PD= 0.980), and D21S2055 and D7S3048 for African (PD = 0.972) populations. The match probabilities were 1 in 6.7 x 10(25) for European, 1 in 1.4 x 10(26) for South Asian and 1 in 1.6 x 10(26) for African populations. These findings established the high discriminatory capacity and robustness of the tested STR loci for forensic identification and kinship testing. (C) 2019 Elsevier B.V. All rights reserved.
