Environmental as well as genetic factors contribute to the heterogeneity in the presentation of diabetic nephropathy. Our objective was to evaluate this heterogeneity within the Caucasian population.</p></sec><sec sec-type="methods"><title>Methods:</title><p>The geo-ethnic origin of the 3409 genotyped Caucasian type 2 diabetes (T2D) patients of Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation was determined using principal component analysis. Genome-wide association studies analyses of age of onset of T2D were performed for geo-ethnic groups separately and combined.</p></sec><sec sec-type="results"><title>Results:</title><p>The first principal component separated the Caucasian study participants into Slavic and Celtic ethnic origins. Age of onset of diabetes was significantly lower in Slavic patients (<italic>P</italic> = 7.3 × 10<sup>−20</sup>), whereas the prevalence of hypertension (<italic>P</italic> = 4.9 × 10<sup>−31</sup>) and albuminuria (5.1 × 10<sup>−9</sup>) were significantly higher. Age of onset of T2D and albuminuria appear to have an important genetic component as the values of these traits were also different between Slavic and Celtic individuals living in the same countries. Common and geo-ethnic-specific loci were found to be associated to age of onset of diabetes. Among the latter, the <italic>PROX1/PROX1-AS1</italic> genes (rs340841) had the highest impact. Single-nucleotide polymorphism rs340841 CC genotype was associated with a 4.4 year earlier onset of T2D in Slavic patients living or not in countries with predominant Slavic populations.</p></sec><sec sec-type="conclusion"><title>Conclusion:</title><p>These results reveal the presence of distinct genetic architectures between Caucasian ethnic groups that likely have clinical relevance, among them <italic>PROX1</italic> gene is a strong candidate of early onset of diabetes with variations depending on ethnicity.</p></sec></div></front><back><div1

The major increased risk of mortality associated with both type 1 diabetes and T2D arises from diabetic nephropathy [<xref rid="R2" ref-type="bibr">2</xref>–<xref rid="R4" ref-type="bibr">4</xref>], which is estimated to affect about one-third of individuals with diabetes.</p><p>Different genetic architectures, such as variations in allele frequencies and linkage disequilibrium structure have long been noted between populations of different racial origins and the ability of this hidden population structure to confound genome-wide association studies (GWAS) findings has been well documented [<xref rid="R5" ref-type="bibr">5</xref>–<xref rid="R8" ref-type="bibr">8</xref>]. Moreover, it is known that GWAS using populations of differing racial backgrounds may help identify different sets of associated genes for complex diseases and drug responses [<xref rid="R9" ref-type="bibr">9</xref>–<xref rid="R11" ref-type="bibr">11</xref>]. Differences in genetic risks have been shown among Caucasians, Africans, and Asians for T2D [<xref rid="R12" ref-type="bibr">12</xref>–<xref rid="R16" ref-type="bibr">16</xref>] and for chronic kidney disease (CKD) [<xref rid="R17" ref-type="bibr">17</xref>–<xref rid="R19" ref-type="bibr">19</xref>]. Evidence exists for population substructure within Caucasian samples as well [<xref rid="R20" ref-type="bibr">20</xref>,<xref rid="R21" ref-type="bibr">21</xref>].</p><p>It is also well established that both environmental and genetic factors contribute to the occurrence of hypertension, diabetes, and CKD [<xref rid="R22" ref-type="bibr">22</xref>–<xref rid="R25" ref-type="bibr">25</xref>]. To distinguish the effects of environmental and lifestyle factors from genetic effects in explaining phenotypic differences in the development of renal complications of T2D, we studied T2D study participants of Caucasian origin and European descent from the Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation trial (ADVANCE) [<xref rid="R26" ref-type="bibr">26</xref>]. Study participants were recruited from a range of European countries as well as from countries of European settlements such as Canada, Australia, and New Zealand. Using principal component analysis (PCA), we identified two main ethnic genetic profiles (Celtic and Slavic) within the ADVANCE Caucasian study participants. To assess the relative effects of genetic and environmental factors, we compared study participants with a Slavic genetic profile living in countries with predominantly Celtic populations with individuals with a Slavic genetic profile living in predominantly Slavic countries of Europe. Significant differences between Slavs living in Slavic and Celtic countries would suggest an environmental/lifestyle effect, whereas no differences between Slavs living in Celtic or Slavic countries would support an impact of genetic influence.</p><p>As age of onset of T2D appears to be more dependent on genetic than environmental factors, we performed GWAS for ‘age of onset of T2D’ within the two ethnic groups separately and for the combined sample.</p></sec><sec sec-type="methods"><title>METHODS</title><sec><title>Sample</title><p>In total, 11 140 participants recruited from 215 centers in 20 countries who were 55 years or older and had T2D since the age of 30 years or older were enrolled in ADVANCE, a factorial randomized controlled clinical trial of blood pressure (BP) lowering and intensive glucose control. All participants were ascertained for high outcome risk according to one of the following criteria: a history of major macrovascular or microvascular disease or diagnosis of T2D 10 years prior to entry in study or presence of another major risk factor for vascular disease, including smoking, dyslipidemia or microalbuminuria, or being 65 years or older. Detailed study methods have been published elsewhere [<xref rid="R26" ref-type="bibr">26</xref>].</p><p>Approval to conduct the trial was obtained from the ethics committee of each study center, and all participants provided written informed consent for the study conduct and a specific, separate consent for genetic substudy. Genotyping was performed only in patients who consented to the genetic substudy.</p></sec><sec><title>Complication phenotypes</title><p>Several phenotypes associated with diabetes and its complications were determined at baseline in each study participants by the ADVANCE study team. These included age at baseline, age at diagnosis of T2D, duration of diabetes at baseline, BMI, blood glucose, glycated hemoglobin, treatment for hypertension, heart rate, and SBP and DBP. Renal phenotypes included estimated glomerular filtration rate (eGFR), in ml/min per 1.73 m<sup>2</sup>, estimated from serum creatinine levels using the CKD-Epidemiology Collaboration formula [<xref rid="R27" ref-type="bibr">27</xref>] and albuminuria, expressed as a ratio of urinary albumin and creatinine in μg/mg [urinary albumin–creatinine ratio (UACR)].</p></sec><sec><title>Genotyping</title><p>In this study, we have genotyped 3629 Caucasian study participants using the Affymetrix Genome-Wide Human SNP Arrays 5.0 or 6.0 (Affymetrix, Santa Clara, California, USA) following standard protocols recommended by the manufacturer. A quality control filtering step was applied to the genotype calls. The microarray data was analyzed using the Affymetrix power tools and individuals with a quality control call rate lower than 86% were filtered out. Additional quality control steps included coarse-grain stratification to ensure a Caucasian population ratio more than 0.8 (STRUCTURE software [<xref rid="R28" ref-type="bibr">28</xref>]), a genetic relatedness check to ensure independent samples (PLINK) and a sex check to ensure genetic accuracy and database integrity [<xref rid="R29" ref-type="bibr">29</xref>]. Quality control was also performed on the final genotypes to remove any single-nucleotide polymorphism (SNPs) with more than 4% of missing values across the entire cohort and any sample with more than 2% of missing SNP genotypes. A more stringent threshold was used for any SNPs with between 1 and 5% minor allele frequencies (MAF). Any of these low MAF SNPs with more than 1% of missing values was removed prior to the imputation; nonetheless, only SNPs with MAF higher than 5% were retained after imputation for use in the GWAS. After completion of the quality control process, a total of 3409 genotyped individuals remained available for analysis.</p></sec><sec><title>Principal component analysis</title><p>A subset of 139 186 independent SNPs was selected from the set of common genotyped SNPs from 5.0 and 6.0 arrays using the linkage disequilibrium pruning application subroutine from PLINK. This set of SNPs was used to perform a PCA for the ADVANCE study participants of Caucasian origin using the EIGENSOFT 3.0 package [<xref rid="R7" ref-type="bibr">7</xref>]. The first principal component (PC1) was used to characterize the ethnic profiles of individuals form this Caucasian population that was sampled in European countries ranging east to west from Russia to Ireland and also from countries with populations of European descent, including Canada, Australia, and New Zealand.</p></sec><sec><title>Imputation</title><p>Two sets of imputation were performed separately for the individuals genotyped on Affymetrix arrays 5.0 and 6.0 using SHAPEIT [<xref rid="R30" ref-type="bibr">30</xref>] and IMPUTE2 software [<xref rid="R31" ref-type="bibr">31</xref>] and the 1000 genome project [<xref rid="R32" ref-type="bibr">32</xref>] phased 3 data set as reference. Only those SNPs with a MAF greater than or equal to 5% and with an imputation quality score greater than or equal to 0.80 were kept as has been proposed in previous studies [<xref rid="R33" ref-type="bibr">33</xref>].</p></sec><sec><title>Statistical analysis</title><p>Analyses of the differences in phenotype values (mean values for quantitative traits and numbers of individuals affected for qualitative traits) between groups (between individuals with Celtic and Slavic genetic profiles; between individuals with Slavic profiles living in predominantly Germano–Celtic European or European descent countries (Celtic region) and individuals with Slavic profiles living in predominantly Slavic European countries (Slavic region); and between individuals with Slavic genetic profiles living in predominantly Germano–Celtic European countries and individuals with Celtic profiles living in those countries were performed using general linear models included in the R statistical package [<xref rid="R34" ref-type="bibr">34</xref>].</p><p>Differences in age of onset of diabetes and duration of diabetes were tested using sex as a covariate. All other phenotype differences were tested using age and sex as covariates so that the significance of these differences are age and sex adjusted.

When appropriate, adjustment for treatment for such traits as SBP, UACR, and eGFR were done using nonparametric adjustment as described [<xref rid="R36" ref-type="bibr">36</xref>].</p></sec><sec><title>Genome-wide association studies</title><p>GWAS were performed for age of onset of T2D separately for individuals with a Celtic or Slavic genetic profile as determined by their value for PC1 and for the combined Celtic and Slavic sample using linear regression with an additive genetic model and sex as well as the two respective first principal components of population stratification as covariates.</p><p>Association analyses were performed separately on the two imputed datasets for individuals that were genotyped on the different arrays (5 986 672 SNPs for 1015 individuals genotyped on chip 5.0 and 6 442 695 SNPs for 2394 individuals genotyped on chip 6.0) and results were merged using a fixed effects meta-analysis routine in the PLINK software [<xref rid="R29" ref-type="bibr">29</xref>] to avoid the possibility of any bias that might have arisen from uneven phenotype distributions across different genotyping chip technologies. The combined meta-analysis data set contained a total of 5 045 527 SNPs that passed all previous quality control steps in both data sets and also passed a combined test for Hardy–Weinberg equilibrium using a critical <italic>P</italic> value of 1 × 10<sup>−3</sup> (<italic>P</italic> < 10<sup>−3</sup>).</p></sec><sec><title>Effect size</title><p>The relative effect sizes (<italic>γ</italic><sub>j</sub>) for each SNP, weighted by the size of the β coefficient of regression (<italic>β</italic><sub>j</sub>), the standard error of <italic>β</italic><sub>j</sub> (Se<italic>β</italic><sub>j</sub>), and the MAF of the SNP (MAF<sub>j</sub>) were estimated by the following equation [<xref rid="R37" ref-type="bibr">37</xref>]: <disp-formula id="MU1"><graphic xlink:href="jhype-35-s24-g001.jpg" position="float"></graphic></disp-formula></p></sec></sec><sec sec-type="results"><title>RESULTS</title><p>PCA of 3409 genotyped ADVANCE study participants using EIGENSOFT 3.0 package identified two major principal components.

Individuals with Slavic profiles had T2D at a younger age (<italic>P</italic> = 7.3 × 10<sup>−20</sup>), had higher SBP and DBP (<italic>P</italic> = 4.5 × 10<sup>−22</sup> and <italic>P</italic> = 5.3 × 10<sup>−29</sup>, respectively) despite the fact that a larger number of them were treated for hypertension and that they had a higher UACR at baseline (<italic>P</italic> = 5.1 × 10<sup>−9</sup>) even after adjusting for age, sex, and medication.</p><p>We then determined the effect of ethnic origin (Celtic vs. Slavic) and environment (Celtic region vs. Slavic region) on the most divergent phenotypes between Slavic and Celtic patients namely age of onset of T2D, BP, and renal function.</p><p>To assess the relative effects of genetic and environmental factors on the differences between individuals with Celtic and Slavic profiles, we compared study participants with a Slavic genetic profile living in countries with predominantly Germano–Celtic populations with individuals with a Slavic genetic profile living in predominantly Slavic countries of Europe. Significant differences between Slavs living in Slavic and Celtic countries would suggest an environmental/lifestyle effect, whereas no differences between Slavs living in Celtic or Slavic countries would support an impact of genetic influence. As shown in Fig. <xref ref-type="fig" rid="F2">2</xref>a, the highly significant earlier age of onset of T2D observed in individuals of Slavic origin was also present among the 175 Slavic study participants living in countries of predominantly Celtic populations, suggesting a genetic drive for this trait. Similarly, UACR was higher in Slavic individuals living in either Slavic or Celtic regions (Fig. <xref ref-type="fig" rid="F2">2</xref>c). This contrasted with eGFR that was higher in Celtic than Slavic individuals after adjustment of age, sex, and medication but was not different between Celtic and Slavic individuals living in the same environment (Fig. <xref ref-type="fig" rid="F2">2</xref>d). SBP is another good example of environmental effect as SBP was higher in Slavic than Celtic individuals but not different between Slavic and Celtic individuals living in Celtic countries (Fig. <xref ref-type="fig" rid="F2">2</xref>b).</p><fig id="F2" position="float"><label>FIGURE 2</label><caption><p>Effect of ethnic origin (Celtic vs. Slavic) and environment (Celtic region vs. Slavic region) on age of onset of T2D, SBP, UACR, and eGFR<sub>CKD-EPI</sub>.

Seven independent SNPs (not in linkage disequilibrium with each other) were found to be associated with age of onset of diabetes at <italic>P</italic> < 10<sup>−5</sup> having the most significant <italic>P</italic> value for the combined Celtic and Slavic cohorts, and thus considered replicated by the above criteria. Other SNPs were associated specifically to one or the other ethnic group. Nine independent SNPs were significant only for the Celtic group and a different set of nine independent SNPs were significant only for the Slavic group. Two SNPs within the same locus were associated with age of onset of diabetes in the two different groups.

We have recently reviewed the importance of lifestyle behavior in gene–environment interactions analysis [<xref rid="R24" ref-type="bibr">24</xref>]. The current study is adding the notion that analysis of migration of a population within a distinct population even before its admixture may help dissect environmental from genetic contributions.</p><p>There is some debate as to the original homeland of the Balto-Slavs. One hypothesis holds that modern Baltic and Slavic populations descend from a proto-Slavonic parental group most likely located in a homeland roughly corresponding to the modern western Ukraine and then expanded by the sixth and seventh centuries A.D. as the Prague–Penkov–Kolochin complex of cultures to an area defined by the Baltic Sea in the north, approximately the Volga river in the east, the area defined by the modern day Czech Republic and the Elbe River in modern Germany in the west and the Danube basin in the south [<xref rid="R43" ref-type="bibr">43</xref>].</p><p>The area of north eastern Germany between the Oder and Elbe rivers was occupied by the Polabian Slavic ethnic group by the sixth century. By the ninth century conflicts between Christian Germanic people and these western pagan Slavs began. The conflicts eventually resulted in the incorporation of the area into the Holy Roman Empire by the thirteenth century and the linguistic germanification of the populations [<xref rid="R44" ref-type="bibr">44</xref>]. Therefore, it is reasonable to hypothesize the surviving presence of genetic evidence for an ethnic divide between a Germano–Celtic group (here referred to as simply ‘Celtic’) and a Balto-Slavic group (here referred to simply as ‘Slavic’) centered roughly along the Elbe river and the border of Czech republic in northern Europe. We have demonstrated that evidence of this ancestral Celtic–Slavic genetic divide still exists in the modern European population and that it is reflected in differences in genetic–phenotype correlations.</p><p>Noticeably, the Caucasian populations of the non-European countries involved in ADVANCE have founding populations that are principally of Germano–Celtic origin as a result of British Empire expansion. Slavic migration is more recent in these countries and therefore represents a minor ethnic component.</p><p>The principal difference between the Celtic and Slavic ethnic groups is age of onset of T2D, which is also correlated with other phenotypes such as albuminuria. We have previously introduced the concept of accelerated aging as being a primary cause of many complex genetic diseases [<xref rid="R45" ref-type="bibr">45</xref>]. It is a strong possibility that individuals with a Slavic genetic profile, despite their environment, are genetically more susceptible to accelerated aging resulting in earlier onset of T2D and associated albuminuria. In addition, our results from ADVANCE demonstrated that in contrast to macrovascular complications of diabetes that are strongly age dependent with an added risk conferred by duration of diabetes, the adverse effects of duration of diabetes on microvascular events were observed in the youngest age group [<xref rid="R46" ref-type="bibr">46</xref>], which is also compatible with observations of the Treatment Options for type 2 Diabetes in Adolescents and Youth trial [<xref rid="R47" ref-type="bibr">47</xref>]. Although the ADVANCE trial amply demonstrated, the decrease of renal events and total mortality by intensification of BP as well as of blood glucose control [<xref rid="R48" ref-type="bibr">48</xref>], a finding that is confirmed for glycemic control in the Veteran's Affairs Diabetes Trial and Action to Control Cardiovascular Risk in Diabetes trials [<xref rid="R49" ref-type="bibr">49</xref>], the current study suggests that further specific functional benefits on eGFR and UACR should be analyzed with respect to geo-ethnicity.</p><p><italic>PROX1</italic> encodes the prospero homeobox 1 protein, a human homologue of the Drosophila prospero gene. This protein is a homeobox transcription factor involved in developmental processes such as cell fate determination, gene transcriptional regulation, and progenitor cell regulation in a number of organs. It plays a critical role in embryonic development. <italic>PROX1</italic> has been shown to be associated with diabetes and its complications in a number of studies [<xref rid="R38" ref-type="bibr">38</xref>–<xref rid="R41" ref-type="bibr">41</xref>,<xref rid="R50" ref-type="bibr">50</xref>–<xref rid="R52" ref-type="bibr">52</xref>]. Here, we present evidence that the genetic influence of <italic>PROX1</italic> on age of onset of diabetes is different within Caucasian ethnic groups. It is of interest that several polymorphisms at this locus are associated with insulin levels and its control in adolescence, selected for a lesser impact of environmental determinants at this age by Lecompte <italic>et al</italic>. [<xref rid="R40" ref-type="bibr">40</xref>]. As we have mentioned, the ADVANCE trial demonstrated that earlier onset of diabetes has more impact on micro than macrovascular complications [<xref rid="R46" ref-type="bibr">46</xref>]. We propose that earlier onset of T2D in context of genetic × environmental influences and ethnicity deserves further attention as a potential new target for early detection and intervention in T2D.</p><p>In conclusion, genetic analyses have to consider geo-ethnic characteristics even within Caucasians, demonstrated here for cardinal features of T2D. Our data suggest that understanding of distinct genomic architectures is important to ascertain clinical utility.</p></sec><sec><title>ACKNOWLEDGEMENTS</title><p>The authors acknowledge the support of grant OPTI-THERA, a private–public initiative of Government of Quebec in ‘Optimization of Therapeutic Approaches in Personalized Primary Care.’</p><p>The project is financed by the ‘Fond de Partenariat pour un Québec Innovant et en Santé’ from the Ministry of Economic Development, Innovation and Export Trade with additional funding from Canadian Institutes of Health Research, Genome Quebec, Servier Canada and Les Laboratoires Servier, Paris, France.</p><sec><title>Conflicts of interest</title><p>There are no conflicts of interest.</p></sec></sec></body><back><fn-group><fn fn-type="other" id="fn1"><label>∗</label><p>Pavel Hamet and Johanne Tremblay are members of College International de Recherche Servier and Johanne Tremblay received honoraria for presentations of ADVANCE at scientific meetings.</p></fn><fn fn-type="equal" id="fn2"><label>†</label><p>Pavel Hamet and Johanne contributed equally to this work.</p></fn></fn-group><fn-group><fn fn-type="abbr"><p>Abbreviations: ADVANCE, Action in Diabetes and Vascular Disease Preterax and Diamicron MR Controlled Evaluation;
