[PMID 17509535] risk of the development of substance dependence significantly increased with the number of "G" alleles at rs6454674 and SNP8 (rs806368);T/T genotypes had significant interaction effects (p = .0003 for comorbid drug dependence (DD) and alcohol dependence (AD), .0002 for DD, and .007 for AD). SNP3 and SNP8 together exerted stronger genetic effects on SD (substance dependence) than either did individually. The peak delta values among all the markers were seen for SNP3 and SNP8 (rs806368)

[PMID 18213623] rs806368(C) together with rs1049353(A) or rs1049353(G) make up a haplotype associated with PTSD, with the C-A haplotype somewhat associated (p=0.04) with higher risk of PTSD and the C-G haplotype associated (p=0.01) with a lower risk of PTSD.

Alcoholic patients with TGT haplotype (corresponding to rs6454674-rs1049353-rs806368 polymorphisms in this order) were less prone to have AD (p = 0.017). TGC haplotype were more likely to develop AD.
[PMID 18179391] Association between single nucleotide polymorphisms in the cannabinoid receptor gene (CNR1) and impulsivity in southwest California Indians.
Impulsivity was significantly associated with the 6-repeat allele of the triplet repeat polymorphism (AATn/A6; p < .0001), as well as four SNPs in or near the CNR1 receptor gene: rs1535255 (p = .001), rs2023239 (p = .004), rs1049353 (p < .001) and rs806368 (p < .0006). These studies provide data to suggest that the CNR1 receptor gene may be significantly associated with impulsivity in SWC Indians.

the associations were female specific. Haplotype 1-1-2 of markers rs2023239-rs12720071-rs806368(C) was associated with nicotine dependence and FTND score in the 2 samples (P < .001 and P = .009, respectively).
