The existing reference database of population samples allows the relationships of new population samples to be inferred on a global level. Analyses show that these autosomal markers constitute one of the better panels of AISNPs. Continuing to build this reference database enhances its value. Because more than half of the 25 ethnic groups recently studied with these AISNPs are from Southwest Asia and the Mediterranean region, we present here various analyses focused on populations from these regions along with selected reference populations from nearby regions where genotype data are available. Many of these ethnic groups have not been previously studied for forensic markers. Data on populations from other world regions have also been added to the database but are not included in these focused analyses. The new population samples added to ALFRED and FROG-kb increase the total to 164 population samples that have been studied for all 55 AISNPs.</p></div></front><back><div1

The existing reference database of population samples allows the relationships of new population samples to be inferred on a global level. Analyses show that these autosomal markers constitute one of the better panels of AISNPs. Continuing to build this reference database enhances its value. Because more than half of the 25 ethnic groups recently studied with these AISNPs are from Southwest Asia and the Mediterranean region, we present here various analyses focused on populations from these regions along with selected reference populations from nearby regions where genotype data are available. Many of these ethnic groups have not been previously studied for forensic markers. Data on populations from other world regions have also been added to the database but are not included in these focused analyses. The new population samples added to ALFRED and FROG-kb increase the total to 164 population samples that have been studied for all 55 AISNPs.</p></abstract><kwd-group kwd-group-type="npg-subject"><title>Subject terms</title><kwd>Population genetics</kwd><kwd>Computational biology and bioinformatics</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution-id institution-id-type="FundRef">https://doi.org/10.13039/100005289</institution-id><institution>United States Department of Justice | National Institute of Justice (NIJ)</institution></institution-wrap></funding-source><award-id>2015-DN-BX-K023</award-id><award-id>2016-DN-BX-0162</award-id><award-id>2014–DN-BX-K030</award-id><principal-award-recipient><name><surname>Kidd</surname><given-names>Judith R.</given-names></name></principal-award-recipient></award-group></funding-group><funding-group><award-group><funding-source><institution>U.S. National Science Foundation, BCS-1444279</institution></funding-source></award-group></funding-group><custom-meta-group><custom-meta><meta-name>issue-copyright-statement</meta-name><meta-value>© European Society of Human Genetics 2019</meta-value></custom-meta></custom-meta-group></article-meta></front><body><sec id="Sec1" sec-type="introduction"><title>Introduction</title><p id="Par2">In previous publications [<xref ref-type="bibr" rid="CR1">1</xref>, <xref ref-type="bibr" rid="CR2">2</xref>] we reported on the increasing number of population samples from major continental regions that had been studied for the panel of 55 ancestry informative single nucleotide polymorphisms (AISNPs) [<xref ref-type="bibr" rid="CR3">3</xref>]. In 2017 there were 139 population samples (representing over 8000 individuals) with data on these AISNPs; analyses indicated that nine biogeographic regions could be distinguished. Allele frequencies and sample sizes have been incorporated into two freely accessible online databases—the ALlele FREquency Database (ALFRED: https//alfred.med.yale.edu) and the Forensic Reference-Resource on Genetics knowledge base (FROG-kb: https//frog.med.yale.edu). Given this global resource, studies of additional populations, especially for geographic regions poorly represented in the current dataset, are likely to be informative on the newly studied regions as well as the global pattern of variation. Here, we describe the newest reference populations that have become available for this set of AISNPs. As more than half of these populations represent ethnic groups from Southwest Asia and the Mediterranean, a number of which have either not been studied before or else not in an integrated manner, we take this opportunity to present analyses focused on groups from this region of the world and selected populations from immediately surrounding geographical region.</p><p id="Par3">From the start of the Neolithic until now, Southwest Asia has been intimately involved in human history and the genetic consequences of the human migrations from and through the region are of considerable interest. Yet populations in this geographical region and nearby areas such as North Africa and Central Asia have not been well represented in the two largest of the human diversity studies, the CEPH-HGDP panel [<xref ref-type="bibr" rid="CR4">4</xref>] and the 1000 Genomes panel (<ext-link ext-link-type="uri" xlink:href="http://www.1000genomes.org">http://www.1000genomes.org</ext-link>) [<xref ref-type="bibr" rid="CR5">5</xref>].

Supplementary Table <xref rid="MOESM1" ref-type="media">S2</xref> details the geographical distribution for the self-reported birthplaces of the individuals from Northern Iraq, belonging to seven different ethnic groups, all of which were residents in Northern Iraq at the time of sample collection.

Genotypes were examined to ensure that the alleles on the positive forward strand have been employed and the allele frequencies have been entered into the databases—ALFRED and FROG-kb.</p><p id="Par7">Principal component analyses (PCA) of the population allele frequencies compared the similarities and differences among the populations. We used XLSTAT 2018 (<ext-link ext-link-type="uri" xlink:href="http://www.xlstat.com/en/about-us/company.html">http://www.xlstat.com/en/about-us/company.html</ext-link>) to calculate the PCs for the populations using their SNP frequencies.

We employed version 2.3.4 applying the standard admixture model assuming correlated allele frequencies. At each <italic>K</italic> value from 6 to 10, the program was run 20 times with 10,000 burn-ins and 10,000 Markov Chain Monte Carlo (MCMC) iterations.

The remaining 9 of 76 populations are not in Table <xref rid="MOESM3" ref-type="media">S5</xref> due to various pre-existing agreements and/or a legal requirement of the country in which the DNA of participating individuals was collected.

As noted, FROG-kb now has all of the new population allele frequencies entered as reference population data. Two Kurds were selected to be examples for the 55 AISNP panel. We are aware that testing them against the entire sample from which they were chosen introduces a slight bias favoring finding them most similar to the Kurdish population. However, given the sample size involved (148 individuals) the bias is very small and can be ignored when using these as examples.</p><p id="Par10">The calculation of likelihoods of ancestry for selected example individuals employed the function in FROG-kb for the Kidd lab 55 AISNP panel. The input is the genotype profile for each individual. For each population the calculation is the product of the frequencies of the genotypes of the input individual across all 55 loci. In the output the populations are ranked from highest to lowest likelihood.</p><p id="Par11">The random match probability (RMP) for each population sample was computed assuming Hardy–Weinberg ratios. While RMP values will differ for each unique genotype, values have been calculated as the expected value based on the allele frequencies in each population. No correction was made for within-sample population structure since the focus is on distinct, well defined population samples representing global population structure.</p><p id="Par12">Population tree diagrams are a common way to represent population relationships. The Neighbor Joining (NJ) method [<xref ref-type="bibr" rid="CR17">17</xref>] is a commonly used algorithm to produce an approximately additive tree, i.e., a tree in which the pairwise genetic distances are additive across the segments (branches) of the tree connecting populations. Under this model the tree structure and the lengths of the segments can be represented as a series of linear equations that can be “solved” by least squares. Each tree structure gives a different set of linear equations. We use the tau genetic distance [<xref ref-type="bibr" rid="CR18">18</xref>], which is theoretically additive in units of random drift. Unfortunately, the NJ approximation does not give an exact least squares estimate and when the NJ structure is evaluated by least squares some segments can have negative estimates of their length. Negative values of genetic drift should not exist and we prefer to find a tree that has all positive values as part of an exact least squares solution to the structure. We have used the LS search program [<xref ref-type="bibr" rid="CR19">19</xref>] to search for a least squares estimate with all positive segments and minimum total length.</p></sec></sec><sec id="Sec5" sec-type="results"><title>Results</title><p id="Par13">The SNP data collected for the 55 AISNPs by the various research groups employing several different methods are consistent in that the same alleles are being detected and the frequencies appear similar to other populations sampled in the same geographical region.

The PCA image (Fig. <xref rid="Fig1" ref-type="fig">1</xref>) of the first and second principal components shows eight distinct clusters emphasized by the color-circle overlays and text labeling. Four of these distinct clusters parse the core area very clearly—North Africa, southernmost SW Asia (mostly the Arabian peninsula), Northern SW Asia (Turkey, Iraq, Iran) and Mediterranean Europe, and Northern Europe. The STRUCTURE results (Fig. <xref rid="Fig2" ref-type="fig">2</xref>) show three main population clusters for the core region (Northern and Mediterranean Europe, Southwest Asia., North Africa); these correspond roughly to similar PCA groupings (Fig. <xref rid="Fig1" ref-type="fig">1</xref>). However, North African and the southern SW Asian area populations look somewhat more alike in the third STRUCTURE cluster in contrast to the PCA result where those areas appear more distinct. North Africa, of course, is only represented here by nine population samples from Tunisia and Libya; it would be interesting to see what relationships the 55 AISNPs would reveal if we had extensive population studies for them from Morocco, Algeria, and Egypt.</p><p id="Par19">One way to think about the way that STRUCTURE defines clusters of individuals in an analysis is that it attempts to find Mendelian populations. From that perspective it becomes clear that the numbers of individuals in each input population is relevant as is the nature of the other populations. For example, a small population with a unique set of different allele frequencies can be absorbed into a large cluster if it is not too different relative to other possible clusterings. The deviation from Hardy–Weinberg ratios will not be that great. On the other hand, if the allele frequencies are different from all other groups, this small population can show membership in several clusters or cause the emergence of a distinct new cluster if the frequency differences are strong enough.</p></sec><sec id="Sec9"><title>Population tree</title><p id="Par20">The large number of negative segments in all trees examined by both the inexact neighbor joining method and the exact least squares method argues strongly against the model of an additive genetic distance for these populations. Although one could find general groupings of populations with similarities to the clusters in the PCA analyses, we conclude that the underlying model of random genetic drift and a tree structure for relationships among the majority of these populations is invalid. The negative segments preclude a drawing. One possible explanation for the negative segments is that the populations are more similar than the model would predict and considerable gene flow would cause that to occur.</p></sec><sec id="Sec10"><title>Population variation</title><p id="Par21">The random match probabilities (RMP) for the new populations in Fig. <xref rid="Fig4" ref-type="fig">4</xref> are in the expected range given the values for the populations previously evaluated for these markers [<xref ref-type="bibr" rid="CR20">20</xref>]. The values of RMP plotted are the expected or average values for the population based on the genotype frequencies. We note that RMP is a measure of the average heterozygosity of a panel and the variation among populations reflects their relative levels of within population variation for these particular SNPs. The values for the African populations are unusually low and this serves as a cautionary note to prevent over interpretation of the differences among populations. All we can confidently say is that differences exist for these markers. Indeed, we might have expected these SW Asian populations to have high levels of heterozygosity given the history of migrations known over the past few thousand years. We see that some populations that are more isolated have higher RMP levels as expected, e.g., Samaritans at 10<sup>−9</sup>, while others such as the Ethiopian Jews have among the lowest values of 10<sup>−13</sup>.</p></sec><sec id="Sec11"><title>Reference samples</title><p id="Par22">A total of 164 population samples (10,356 individuals) now have allele frequencies on all of the 55 Kidd lab AISNPs. Sixteen of the newest reference populations have been studied via commercial kits from ThermoFisher Scientific or from Verogen that employ massively parallel sequencing. Researchers employing these resources will find the enhanced set of reference populations useful in a wide range of forensic, anthropological, and medical genetic studies. Both of the kits include the 55 Kidd AISNPs. The combined 55 Kidd and 128 Seldin [<xref ref-type="bibr" rid="CR21">21</xref>] AISNP sets have 170 different AISNPs. The ThermoFisher Scientific kit includes 165 of these 170 AISNPs. Future analyses by the researchers who have conducted those studies may provide even more information on those populations’ relationships.</p><p id="Par23">The functionality in FROG-kb has been used to compute the relative likelihoods that two Kurdish individuals originate from each of the 164 reference populations now available in FROG-kb for the 55 AISNP panel (Fig. <xref rid="Fig3" ref-type="fig">3</xref>). These examples provide a clear demonstration that genotypes in this region of the world “overlap”. The genotype of Kurd #1 is most likely (among the reference populations) to occur in an Iranian population (Fig. <xref rid="Fig3" ref-type="fig">3</xref>). Based on the samples of the available reference populations, several other populations are more likely to be the origins of the genotype than the Kurdish population. However, although the Kurdish population is the sixth most likely to have generated this genotype, the likelihood ratio of Kurdish to Iranian is not highly significant, i.e., the ratios are less than two orders of magnitude apart. The genotype of Kurd #2 (Fig. <xref rid="Fig3" ref-type="fig">3</xref>) shows that the genotype is most likely to occur in the Kurdish population, based on the reference samples. Most interesting is that it is almost as likely to occur in several other reference populations that show no significant difference as potential origins of this genotype: six other populations have likelihood ratios separated by less than one order of magnitude. These include some of the same population samples that were seen among the not-highly significant reference populations for Kurd #1. These two examples illustrate the same need for caution in estimating ancestry using FROG-kb, or any statistically similar method, as discussed in previous publications [<xref ref-type="bibr" rid="CR3">3</xref>, <xref ref-type="bibr" rid="CR22">22</xref>]. The highest likelihood is also the value for the random match probability for this individual that would be used in a forensic setting. In both cases the value is ~10<sup>−14</sup>, a meaningful value that would be especially valuable in combination with forensic STR markers. For these two examples the RMP values are smaller than the average for Kurds of between 10<sup>−10</sup> and 10<sup>−11</sup> (Fig. <xref rid="Fig4" ref-type="fig">4</xref>). The development of second-tier ancestry panels [<xref ref-type="bibr" rid="CR23">23</xref>, <xref ref-type="bibr" rid="CR24">24</xref>] that can provide more refined differentiation of ancestry among closely related groups within geographical regions will be helpful in resolving at least some of the ambiguities of assignment that occur in ancestry inference panels designed for broader groupings of populations worldwide.<fig id="Fig3"><label>Fig. 3</label><caption><p>The 30 highest likelihoods calculated by FROG-kb for two Kurdish individuals based on the 55 AISNP panel and 164 current reference populations.

We also thank Helle S. Mogensen, Maryam S. Farzad, Torben Tvedebrink, Claus Børsting, and Niels Morling of the University of Copenhagen for their willingness to share genotype data for four of the population samples [<xref ref-type="bibr" rid="CR6">6</xref>, <xref ref-type="bibr" rid="CR8">8</xref>]. Special thanks are due to the many hundreds of individuals who volunteered to give blood or saliva samples for studies of gene frequency variation and to the many colleagues who helped us collect the samples.</p></ack><notes notes-type="ethics"><title>Compliance with ethical standards</title><notes notes-type="COI-statement"><title>Conflict of interest</title><p id="Par24">The authors declare that
