Abstract

Nicotine dependence is one of the world's leading causes of preventable death. To discover genetic variants that influence risk for nicotine dependence, we targeted over 300 candidate genes and analyzed 3713 single nucleotide polymorphisms (SNPs) in 1050 cases and 879 controls. The Fagerström test for nicotine dependence (FTND) was used to assess dependence, in which cases were required to have an FTND of 4 or more. The control criterion was strict: control subjects must have smoked at least 100 cigarettes in their lifetimes and had an FTND of 0 during the heaviest period of smoking. After correcting for multiple testing by controlling the false discovery rate, several cholinergic nicotinic receptor genes dominated the top signals. The strongest association was from an SNP representing CHRNB3, the beta3 nicotinic receptor subunit gene (P = 9.4 x 10(-5)). Biologically, the most compelling evidence for a risk variant came from a non-synonymous SNP in the alpha5 nicotinic receptor subunit gene CHRNA5 (P = 6.4 x 10(-4)). This SNP exhibited evidence of a recessive mode of inheritance, resulting in individuals having a 2-fold increase in risk of developing nicotine dependence once exposed to cigarette smoking. Other genes among the top signals were KCNJ6 and GABRA4. This study represents one of the most powerful and extensive studies of nicotine dependence to date and has found novel risk loci that require confirmation by replication studies.

  • Allelic variation in the α5/α3/β4 nAChR subunit gene cluster at chromosome 15q25 significantly increases risk of tobacco addiction.

    “It has been shown that allelic variation in the α5/α3/β4 nAChR subunit gene cluster located in chromosome region 15q25 significantly increases risk of tobacco addiction (Saccone et al. 2007;Berrettini et al. 2008;Lips et al. 2010).”

  • The most compelling evidence for risk variants contributing to smoking behavior was in the CHRNA5/A3/B4 gene cluster, which encodes the α5, α3, and β4 subunits.

    “The most compelling evidence for risk variants contributing to smoking behavior was in the CHRNA5/A3/B4 gene cluster, which encodes the α5, α3, and β4 subunits.”
  • The most thoroughly investigated and replicated finding to date is the association with rs16969968 in CHRNA5.

    “The most thoroughly investigated and replicated finding to date is the association with rs16969968, in CHRNA5 (91).”
  • SNP rs578776 is strongly associated with nicotine dependence and has a low correlation with rs16969968 (r2 = 0.18), indicating that it represents a statistically independent signal.

    “A second signal in the CHRNA5/A3/B4 cluster is tagged by SNP rs578776; it is strongly associated with nicotine dependence and has a low correlation with rs16969968 (r2 = 0.18), indicating that it represents a statistically independent signal (90,91).”
  • Initiation of smoking behavior and transition to dependence has been found to show strong heritability, with reported heritability coefficients ranging from 30% to greater than 80% (mean approximately 60% for initiation and 70% for progression to dependence).

    “With regard to the latter factors, initiation of smoking behavior and transition to dependence (i.e. persistent smoking) has been found to show strong heritability (60). The reported heritability coefficients range from 30% to greater than 80% (a mean of approximately 60% for initiation and 70% for progression to dependence).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
