ABSTRACT
<p><b>OBJECTIVE</b>To observe the association between SNPs in SOD1 (rs1041740, rs2070424, rs10432782 and rs4998557) and noise-induced hearing loss in Chinese Han population.</p><p><b>METHODS</b>A case-control study was used to study the effects of environmental risk factors on the susceptibility to noise induced hearing loss (NIHL) in 201 sensitive workers and 202 resistant workers. A questionnaire was designed to carry out an investigation, and an occupational health survey was used to identify the occupational risk factors. Genomic DNA was extracted from peripheral blood cells using standard procedures of Takara kit, and 5 ml blood was from each subject. SNPs were detected using standard procedures of TaqMan probe allele identification method.</p><p><b>RESULTS</b>In SOD1 gene, the A allele of rs2070424 was a protective factor of NIHL, compared with the G allele (OR = 0.67, 95%CI 0.50 approximately 0.88). The risk with NIHL in subjects with AA genotype was significantly lower than that in subjects with GG genotype (OR = 0.48, 95%CI 0.26 approximately 0.79). After adjusting the confusion factors, OR was 0.44 and 95%CI was 0.25 approximately 0.78.</p><p><b>CONCLUSION</b>In Chinese Han population, the SNP of rs2070424 in SOD1 may be associated with the susceptibility to NIHL.</p>
