}}[[rs6968865]] is a SNP located near the aryl hydrocarbon receptor [[AHR]] gene on ch 7p21.

A meta-analysis of four GWAS studies of coffee consumption among a total of ~8,000 coffee drinkers of European ancestry found that the [[rs6968865]](T) was strongly associated with increased consumption (p = 2.3 x 10e-11). The estimated effect was an increase of 0.2 cups a day per allele for both this SNP and one other ([[rs2472297]]).{{PMID|21357676|OA=1
