چکیده
OBJECTIVE We aimed to determine whether the single nucleotide polymorphisms (SNPs) on chromosome 9p21 were associated with coronary heart disease (CHD) in a Chinese Han population. METHODS AND RESULTS We determined the genotypes of rs2383206 and rs2383207 on chromosome 9p21 in 1360 CHD patients and 1360 age- and sex-frequency-matched controls from an unrelated Chinese Han population. GG genotypes in rs2383207 occurred more frequently in CHD patients compared to controls, and the odds ratio (OR) was 1.52 (95% CI 1.13 to 2.04), after adjusting for conventional risk factors. In stratified analysis, the risk associated with the GG genotype of the two SNPs was stronger in subjects who were males, less than 60 years old, overweight, and smokers. The SNP rs2383207 had significant interactions with gender and smoking (P=0.018 and 0.037, respectively). The risk allele G of rs2383207 plus family history of CHD had a cumulative association with CHD (P for trend, 1.0x10(-6)); the OR for CHD was 4.59 (95% CI 2.52 to 8.37) for those with all the risk factors as compared with subjects without any of the factors. CONCLUSIONS The SNP rs2383207 on chromosome 9p21 is significantly associated with CHD in Chinese. This SNP combined with family history has a cumulative association with CHD.

No association between single nucleotide polymorphisms in pre-mirnas and the risk of gastric cancer in Chinese population
Objective(s): Accumulating evidence has demonstrated that miRNAs contribute to various genetic and epigenetic modifications in the pathogenesis of gastric cancer (GC). Recent studies focused on the four single nucleotide polymorphisms (SNPs) of pre-miRNAs including rs11614913, rs3746444, rs2910164, and rs2292832. It was suggested that these four SNPs were significantly associated with the risk ...
متن کامل9p21 is a shared susceptibility locus strongly for coronary artery disease and weakly for ischemic stroke in Chinese Han population.
BACKGROUND Recent studies on genome-wide association have identified common variants on chromosome 9p21 associated with coronary artery disease (CAD). Given that ischemic stroke and CAD share several aspects of etiology and pathogenesis, we investigated the association of variants on chromosome 9p21 with ischemic stroke and CAD in the Chinese Han population by capturing the majority of diversit...

Background: Coronary artery disease (CAD) is a multifactorial and heterogenic disease. Recently, genome-wide association studies have reported that rs1333040 (C/T) and rs1004638 (A/T) single nucleotide polymorphisms (SNPs) in the 9p21 locus have very strong association with CAD. This study aimed to examine these associations in Southwest of Iran. Methods: Blood samples were collected from 200 C...

The single nucleotide polymorphisms (SNPs) related to both coronary heart disease (CHD) and ischemic stroke (IS) in Chinese individuals have not been identified definitely. This study was developed to evaluate the genetic susceptibility to CHD and IS on the chromosome 9p21 and the adenosine triphosphate (ATP)-binding cassette transporter A1 genes (ABCA1) in a Chinese Han population. Genotypes o...
