Abstract:
Objective:To investigate the association between the single nucleotide polymorphisms of rs12212067 in FOXO3 gene and the susceptibility to occupational noise-induced deafness in a Chinese Han population.
Methods:A total of 1 066 cases of noise exposure workers from a large chemical fiber factory in Jiangsu Province were selected as the study subjects. All subjects’ basic data and field exposure data were collected through questionnaires and occupational health surveys. The subjects were divided into case group (531 persons, double ear high frequency average hearing threshold>25 dB) and control group (535 persons, double ear high frequency average hearing threshold≤25 dB) according to their results of pure tone hearing test .2ml fasting venous blood was collected for DNA extraction and genotyping was performed by TaqMan-PCR technique.
Results:Genotyping results suggested that the GT+GG genotype is a risk factor for occupational noise-induced deafness, with an adjusted OR 95% confidence interval of 2.044 (1.51-2.78) . After the noise exposure intensity was stratified, the adjusted OR values and the 95% confidence intervals of noise intensity ≤85, 85-92 and>92 dB respectively 2.43 (1.52-3.90) , 2.17 (1.03-4.59) and 1.74 (1.07-2.83) .
Conclusion:GT-GG genotype in rs12212067 of FOXO3 gene may be a risk factor for occupational noise-induced deafness.
