Abstract :
AIMS: A previous association analysis identified polymorphisms in gamma-aminobutyric acid receptor A, subunit 4 (GABRA4) and GABRA2 to be associated with nicotine dependence, as assessed by a score of 4 or more on the Fagerstrom Test for Nicotine Dependence (FTND). In the present report, we extend the previous study by expanding our genotyping efforts significantly for these two genes. DESIGN: In 1049 cases (FTND of 4 or more) and 872 controls (smokers with FTND of 0) from the United States and Australia, we examine the association between 23 GABRA4 and 39 GABRA2 recently genotyped single nucleotide polymorphisms (SNPs) and nicotine dependence using logistic regression-based association analyses using the genomic analysis package PLINK. |
