The genetic contributing factors are considered heterogeneous and several genes have been consistently associated with susceptibility like PARK2, tumor necrosis factor (TNF), lymphotoxin-a (LTA) and vitamin-D receptor (VDR). Here, we combined a case–control study (374 patients and 380 controls), with meta-analysis (5 studies; 2702 individuals) and biological study to test the epidemiological and physiological relevance of the interleukin-10 (IL-10) genetic markers in leprosy. We observed that the À819T allele is associated with leprosy susceptibility either in the case–control or in the meta-analysis studies. Haplotypes combining promoter single-nucleotide polymorphisms also implicated a haplotype carrying the À819T allele in leprosy susceptibility (odds ratio (OR) ¼ 1.40; P ¼ 0.01).

Many existing genetic analysis tools are not designed to handle such large datasets in a convenient manner and do not necessarily exploit the new opportunities that whole-genome data bring. To address these issues, we developed PLINK, an open source C/C++ WGAS toolset. Large datasets, comprising hundreds of thousands of markers geno- typed for thousands of individuals, can be rapidly manipulated and analyzed in their entirety. As well as providing tools to make the basic analytic steps computationally efficient, PLINK also supports some novel approaches to whole-genome data, that take advantage of whole-genome coverage. We in- troduce PLINK and describe the five main domains of function: data man- agement, summary statistics, population stratification, association analysis and identity-by-descent estimation.

Nivard2 1Department of Psychiatry, Amsterdam UMC, University of Amsterdam, Amsterdam, the Netherlands 2Department of Biological Psychology, VU University, Amsterdam, the Netherlands Correspondence: [email protected]; [email protected]; [email protected] Abstract Gene-environment correlations can bias associations between genetic variants and complex traits in genome-wide association studies (GWASs). Here, we control for geographic sources of gene- environment correlation in GWASs on 56 complex traits (N=69,772–271,457). Controlling for geographic region significantly decreases heritability signals for SES-related traits, most strongly for educational attainment and income, indicating that socio-economic differences between regions induce gene-environment correlations that become part of the polygenic signal. For most other complex traits investigated, genetic correlations with educational attainment and income are significantly reduced, most significantly for traits related to BMI, sedentary behavior, and substance use. Controlling for current address has greater impact on the polygenic signal than birth place, suggesting both active and passive sources of gene-environment correlations. Our results show that societal sources of social stratification that extend beyond families introduce regional-level gene-environment correlations that affect GWAS results.

  • A Tutorial on Statistical Methods for Population Association Studies
    FOCUS ON STATISTICAL ANALYSISREVIEWS A tutorial on statistical methods for population association studies David J. Balding Abstract | Although genetic association studies have been with us for many years, even for the simplest analyses there is little consensus on the most appropriate statistical procedures. Here I give an overview of statistical approaches to population association studies, including preliminary analyses (Hardy–Weinberg equilibrium testing, inference of phase and missing data, and SNP tagging), and single-SNP and multipoint tests for association. My goal is to outline the key methods with a brief discussion of problems (population structure and multiple testing), avenues for solutions and some ongoing developments. Haplotype The goal of population association studies is to identify will obtain a clearer picture of the statistical issues and A combination of alleles at patterns of polymorphisms that vary systematically gain some ideas for new or modified approaches. different loci on the same between individuals with different disease states and In this review I cover only population association chromosome. could therefore represent the effects of risk-enhancing or studies in which unrelated individuals of different dis- protective alleles (BOXES 1,2).
