Notes

Associated with nicotine Dependence as part of several haplotypes, based on a study of 1,000+ subjects including both African-Americans and European-Americans. The risk haplotype varies between populations. Among African-Americans, the haplotype C-C-G of rs2491397-rs2184026-rs3750344 had a significant positive association with nicotine dependence. Among European-Americans, for rs1435252-rs3780422-rs2779562-rs3750344, the C-A-C-A haplotype was positively associated with nicotine dependence while the T-A-T-A haplotype was negatively associated.
