Association between NF-κBI and NF-κBIA polymorphisms and coronary artery disease.

Coronary artery disease (CAD) is the leading cause of fatalities worldwide. Nuclear factor (NF)-κB is a transcription factor that controls cell proliferation, differentiation and immunity. To the best of our knowledge, the present study is the first investigation of the association between CAD and -94 W/D/ 3'-untranslated region (3'-UTR) A→G polymorphisms. The study population comprised 226 CAD patients and 201 controls. There was no significant difference in 3'-UTR A→G in the allele and genotype frequencies between case and control populations. The D allele frequency of -94 in the case group was significantly higher compared to the control group (P=0.028, odds ratio=1.37). The genotype frequency of -94 DD in the case group was significantly higher compared to the controls (P=0.028). Linkage analysis showed a close linkage among these 2 genes (P<0.001 for case and control), and AD and GD haplotypes were associated with CAD (P<0.001; P=0.015, respectively). -94 DD genotype can be a significant risk factor for the development of CAD.
