Another review article conducted by Chen et al. (2022) on Chinese Han people (n = 2400), occupationally exposed to noise, recorded that the SOD1 AA genotype (rs2070424) was protective against NIHL, while (rs10432782) the SOD1 GG genotype and (rs4880) CT genotype of (SOD2 V16A SNP) was in association with higher occurrence of NIHL. This evidence concerns the gene SOD1 and noise induced hearing loss.
