OBJECTIVE: To investigate the relationship between single nucleotides polymorphism of catalase(CAT) gene and susceptibility to noise-induced hearing loss(NIHL) in occupational noise exposed population.
METHODS: A case-control study of 1∶1 was conducted to select 286 workers with binaural high frequency average hearing threshold ≥40 dB(HL), from 2006 to 2015 in a cohort study of occupational noise exposure workers in Henan Province. According to the type of work, the age difference was not more than 5 years and the length of exposure to noise was not more than 2 years. The polymorphism of 8 single nucleotides in CAT gene was detected by medium SNPscanTM, and the relationship between 8 single nucleotides polymorphism of CAT gene and NIHL susceptibility was analyzed by multivariate conditional logistic regression.
RESULTS: Under the dominant model of rs208679 locus of CAT gene [(GA GG)/AA], the risk of NIHL in individuals carrying GA or GG genotype was 1. 431 times higher than that in individuals carrying AA genotype(95%CI 1. 020-2. 009), and P=0. 038.
CONCLUSION: G, a mutant at rs208679 site of CAT gene, may be one of the risk factors for NIHL susceptibility.
