This work aims to review the structure and functioning of the α4β2 nAChR emphasizing its role in the treatment of associated diseases like nicotine addiction and underlying pathologies such as cognition, depression and attention-deficit hyperactivity disorder.
Our results suggested that the CHRNA4rs1044396 CT/TT genotype is related to cigarette smoking, that the rs1044397 polymorphism may associate with PD age of onset in women, and that rs1044396 and rs1044397 may relate to pain in PD patients, but not to the course or severity of disease, or to depression or nocturnal or sleeping disorders.
We identified a significant epistasis effect BCL1 by CHRNA4 showing that carriers of the CC genotype at the BCL1 locus who were also homozygous for the T allele at the CHRNA4 locus had the highest depression scores.

Thus, we also briefly review data generated from genetically modified mice to support a role for discrete nAChR subunits in anxiety disorders, depression, and schizophrenia.
