AIMS: To understand the role of ancestral genomic background in substance dependence (SD) genome-wide association studies (GWAS), we analyzed population diversity at genetic loci associated with SD traits and evaluated its effect on GWAS outcomes. MATERIALS & METHODS: We investigated 24 genes with variants associated with SD by GWAS; and 82 loci with putative subordinate roles with respect to SD-associated genes. RESULTS: We observed high ancestry-related frequency differences in common functional alleles in GWAS relevant genes and their interactive partners. Common functional alleles with high frequency differences demonstrated significant effects on the GWAS outcomes. CONCLUSION: Population differences in SD GWAS outcomes seem not to be influenced by general variation across the genome, but by ancestry-related local haplotype structures at SD-associated loci.
Frequency differences values of common variants among ancestry groupsEach ancestry-specific line is made up by symbols that represent single variants. For color figures, see online at: http://www.futuremedicine.com/doi/full/10.2217/PGS.15.91
Occurrence of functional rare variants in drug-dependence genes and their interactive partners among ancestry groups (Africa: triangles; admixed America: red circles; Asia: green square; Europe: blue diamonds)Each symbol represents a gene. Trend lines for each ancestry groups are also reported (Africa: r2 = 0.92, p < 0.001; admixed America: r2 = 0.90; p < 0.001; Asia r2 = 0.90; p < 0.001; and Europe: r2 = 0.90; p < 0.001).
