A polymorphism in human estrogen-related receptor beta (ESRRβ) predicts audiometric temporary threshold shift.


ABSTRACT:

Objective

A non-synonymous single nucleotide polymorphism (rs61742642; C to T, P386S) in the ligand-binding domain of human estrogen-related receptor beta (ESRRβ) showed possible association to noise-induced hearing loss (NIHL) in our previous study.

Design

This study was conducted to examine the effect of the ESRRβ rs61742642 T variant on temporary threshold shift (TTS). TTS was induced by 10 minutes of exposure to audiometric narrow-band noise centered at 2000 Hz. Hearing thresholds and distortion product otoacoustic emissions input output function (DP IO) at 2000, 3000, and 4000 Hz were measured before and after the noise exposure.

Study sample

Nineteen participants with rs61742642 CT genotype and 40 participants with rs61742642 CC genotype were recruited for the study.

Results

Participants with the CT genotype acquired a significantly greater TTS without convincing evidence of greater DP IO temporary level shift (DPTLS) compared to participants with the CC genotype.

Conclusion

The results indicated that the ESRRβ polymorphism is associated with TTS. Future studies were recommended to explore molecular pathways leading to increased susceptibility to NIHL.
