Abstract:
Objective:To explore the effect of gene polymorphism on workers suffering from noise induced hearing loss (NIHL) .Methods:In May 2019, a case-control study was conducted to select noise exposed workers in five factories in Zhejiang Province from 2017 to 2018. The average hearing threshold of binaural high frequency (3, 4, 6 kHz) was >25 dB (A) as the NIHL group, and the hearing threshold of any language frequency (0.5, 1, 2 kHz) was ≤25 dB (A) as the non NIHL group, with 307 people in each group. The general demographic data, occupational history, pure tone audiometry results and oral swab mucosal samples of noise exposed workers were collected, and the DNA of oral mucosal cells was extracted. The relationship between genetic risk score (GRS) and NIHL was analyzed, single nucleotide polymorphisms (SNP) were genotyped, the relationship between genotype and NIHL was analyzed by logistic regression, and the relationship between haplotype and NIHL was analyzed by R language.Results:After adjusting for gender, age, education and working years, the risk of NIHL among workers carrying cysteine-aspartic acid protease 3 gene ( CASP3) rs1049216 recessive model GG genotype, rs6948 recessive model TT genotype, NADPH oxidase 3 gene ( NOX3) rs12195525 additive model GT genotype and dominant model TT+GT genotype decreased ( P<0.05) , the risk of disease was higher in workers with AA genotype carrying cysteine-aspartic acid protease 7 gene ( CASP7) rs12415607 additive model ( P<0.05) . There was a strong linkage disequilibrium (LD) relationship between rs1049216 and rs6948 ( D'>0.8) . Haplotype AT and GG composed of rs1049216-rs6948 increased the risk of NIHL ( P<0.05) . The risk of NIHL increased with the increase of GRS ( OR=2.69, P<0.05) . Conclusion:Genotype polymorphisms at rs1049216 and rs6948 ( CASP3) , rs12195525 ( NOX3) , rs12415607 ( CASP7) may be associated with susceptibility to NIHL.
