ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the relationship between osteopontin gene genetic polymorphisms and susceptibility of nasopharyngeal carcinoma in Guangxi Zhuang people.</p><p><b>METHODS</b>With a hospital based case-control study, osteopontin gene polymorphisms were compared between patients with nasopharyngeal carcinoma and healthy outpatients as a controls in Zhuang population in Guangxi. The single nucleotide polymorphisms at rs1126772 and rs9138 sites of the osteopontin gene were determined by polymerase chain reaction-single base extension technique (PCR-SBE) and DNA sequencing technology. The comparison between genotype and allele frequency distribution differences in case and control group was accomplished by a χ(2) test. The frequencies of haplotypes in osteopontin gene in different groups were analyzed.</p><p><b>RESULTS</b>There were no differences between the patients and controls in the genotype or allele frequencies of osteopontin gene rs1126772 site (</p><p><b>GA/GG</b>OR = 0.94, 95%CI 0.37-2.37, χ(2) = 0.182, P = 0.891; AA/GGOR = 0.86, 95%CI 0.35-2.12, χ(2) = 0.834, P = 0.773) or rs9138 site (</p><p><b>CA/CC</b>OR = 1.42, 95%CI 0.88-2.29, χ(2) = 2.023, P = 0.155; AA/CCOR = 1.77, 95%CI 0.78-4.01, χ(2) = 1.901, P = 0.168). The frequency of GA haplotype in the patients was significantly higher than that in the controls (P = 0.003), and the GA haplotype was associated with a significantly increased risk of nasopharyngeal carcinoma (OR = 4.84, 95%CI 1.59-14.71).</p><p><b>CONCLUSION</b>The haplotype GA of osteopontin gene rs1126772 and rs9138 sites increases the risk of nasopharyngeal carcinoma in Guangxi Zhuang people.</p>
