Human Gene Set: SPIELMAN_LYMPHOBLAST_EUROPEAN_VS_ASIAN_DN


Standard name SPIELMAN_LYMPHOBLAST_EUROPEAN_VS_ASIAN_DN
Systematic name M16066
Brief description Genes down-regulated in lymphoblastoid cells from the European population compared to those from the Asian population.
Full description or abstract Variation in DNA sequence contributes to individual differences in quantitative traits, but in humans the specific sequence variants are known for very few traits. We characterized variation in gene expression in cells from individuals belonging to three major population groups. This quantitative phenotype differs significantly between European-derived and Asian-derived populations for 1,097 of 4,197 genes tested. For the phenotypes with the strongest evidence of cis determinants, most of the variation is due to allele frequency differences at cis-linked regulators. The results show that specific genetic variation among populations contributes appreciably to differences in gene expression phenotypes. Populations differ in prevalence of many complex genetic diseases, such as diabetes and cardiovascular disease. As some of these are probably influenced by the level of gene expression, our results suggest that allele frequency differences at regulatory polymorphisms also account for some population differences in prevalence of complex diseases.
