Human | DDC | 1644 | dopa decarboxylase (aromatic L-amino acid decarboxylase) | Association of the DOPA decarboxylase (DDC) gene on chromosome 7p11 with measures of nicotine dependence Single nucleotide polymorphisms in the dopa decarboxylase gene is associated with nicotine dependence association of alleles and haplotypes at the DOPA decarboxylase (DDC) locus with the DSM-IV diagnosis of nicotine dependence |
Human | CYP2E1 | 1571 | cytochrome P450, family 2, subfamily E, polypeptide 1 | association of CYP2E1*1D with alcohol and nicotine dependence suggests that CYP2E1 may contribute to the development of these dependencies |
Human | CYP2A6 | 1548 | cytochrome P450, family 2, subfamily A, polypeptide 6 | CYP2A6 genotypes are related with nicotine dependence, influencing smoking habits and withdrawal symptoms in quitting smoking |
Human | CNR1 | 1268 | cannabinoid receptor 1 (brain) | CNR1 gene assosiated with nicotine dependence |
Human | CHRNB4 | 1143 | cholinergic receptor, nicotinic, beta 4 (neuronal) | In the 2,827 long-term smokers examined, common susceptibility and protective haplotypes at the CHRNA5-A3-B4 locus were associated with nicotine dependence severity |
Human | CHRNB2 | 1141 | cholinergic receptor, nicotinic, beta 2 (neuronal) | A common haplotype of the nicotine acetylcholine receptor alpha 4 subunit gene is associated with vulnerability to nicotine addiction in men CHRNB2 is a logical candidate for influencing smoking behavior and nicotine dependence |
