The combination of a genome-wide association study of lymphocyte count and analysis of gene expression data reveals novel asthma candidate genes.

Our goal was to integrate the two lists in order to test whether genes tend to be ranked at the top of both lists more often than expected by chance alone. We hypothesized that SNPs that show evidence for a genetic association with lymphocyte count by GWAS will often be in proximity to genes that show independent evidence for differences in expression levels between individuals with high or low lymphocyte count. To test this hypothesis, we first paired genes and nearby SNPs.
