| Abstract |
Based on our previously identified linkage regions for nicotine dependence (ND), we selected six and five single nucleotide polymorphisms (SNPs) in the muscarinic cholinergic receptor subtype M1 (CHRM1) and nicotinic cholinergic receptor beta1 (CHRNB1), respectively, to determine the association of the two genes with ND in a total of 2,037 subjects from 602 nuclear families of either African-American (AA) or European-American (EA) origin. Individual SNP- and/or haplotype-based analyses indicated that the CHRNB1 was significantly associated with ND, which was assessed by smoking quantity (SQ), the Heaviness of Smoking Index (HSI), and the Fagerström Test for ND (FTND), in both ethnic samples. The association of rs2302763 in the CHRNB1 was significant with adjusted SQ in the EA sample after correction for multiple testing (P=0.013). Haplotype A-T-A formed by SNPs rs2302765, rs2302762, and rs9217 in the CHRNB1 was significantly associated with the high risk allele for all the three ND measures (minimum P=0.009, 0.006, and 0.008 for SQ, HSI and FTND, respectively) in the AA sample while haplotype A-T-A formed by rs2302765, rs2302763, and rs9217 was significantly positively associated with ND (minimum P=0.005, 0.016, and 0.016 for SQ, HSI and FTND, respectively) in the EA sample. The CHRM1 exhibited significant protective associations of haplotype C-C-A-T-G-G formed by all six SNPs of this gene with at least one ND measure in the AA sample after Bonferroni correction (minimum P=0.008, 0.013, and 0.009 for SQ, HSI and FTND, respectively), but no significant association was found in the EA sample. The significant associations, together with their location of linked region to ND, suggest that the CHRNB1 and CHRM1 are likely candidates for further investigation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 January 2008.
All research outputs
#8,882,501
of 26,017,215 outputs
Outputs from Human Genetics
#1,082
of 3,050 outputs
Outputs of similar age
#31,793
of 94,002 outputs
Outputs of similar age from Human Genetics
#9
of 22 outputs
Altmetric has tracked 26,017,215 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,050 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.1. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 94,002 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 22 others from the same source and published within six weeks on either side of this one. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
