Association between single nucleotide polymorphism locus rs189037 in the promoter of ATM gene and nasopharyngeal carcinoma susceptibility in Cantonese / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the correlation between single nucleotide polymorphisms (SNP) in the promoter of ataxia-telangiectasia mutated (ATM) gene and the susceptibility of nasopharyngeal carcinoma in Cantonese.</p><p><b>METHODS</b>A total of 176 NPC Cantonese NPC patients and 202 age-matched healthy controls were enrolled in this study. G/A genotyping of the SNP locus rs189037 in the promoter of ATM gene was performed by PCR and direct sequencing of the PCR products.</p><p><b>RESULTS</b>The genotype frequency of heterozygote G/A was 50% (88/176) and 47.5% (96/202), and that of the homozygote variant A/A was 15.3% (27/176) and 18.3% (37/202) in NPC patients and healthy individuals, respectively. Statistics analysis revealed no evident correlations of the G/A and A/A genotypes to the clinical phenotypes of NPC in either NPC group or healthy control group (OR7equals;1.022, 95%CIequals;0.668-1.564 for G/A+A/A). Analysis after stratification by age and gender found no such correlations either.</p><p><b>CONCLUSION</b>The genotype frequencies of SNP locus rs189037 in the promoter of ATM gene are similar between NPC patients and healthy subjects, suggesting that rs189037 is not related to the genetic susceptibility of NPC in Cantonese.</p>
