KCNE1 and noise induced hearing loss: Pawelczyk et al. (2009) performed a study to clarify the hypothesis that genetic variability in genes of the potassium recycling pathway may be a risk factor for the development of NIHL. The significant results revealed that the AA genotype in rs2070358 appeared more frequently in resistant individuals than in susceptible ones, while genotype GG was more often among susceptible subjects. Recently, another study (Ding et al., 2020) was designed to investigate the association between genetic mutations in the KCNE1 gene and susceptibility to NIHL in the Chinese population.
