The aim of the present study was to elucidate the role of the non‑syndromic autosomal recessive deafness 12 allelic variant of cadherin 23 (CDH23) in Chinese patients with non‑syndromic hearing loss. The present study focused on a Chinese family with hearing loss in which there were two siblings with autosomal, recessive deafness, ranging from severe to profound hearing loss over all frequencies. DNA sequencing was used to assess the genetic factors in the disease etiology. The data revealed a compound heterozygous mutation of CDH23 in both patients. Genetic CDH23 variants are known to be responsible for non‑syndromic hearing loss, and CDH23 variants frequently occur in various populations, including Japanese and Republic of Korean. Results from the present study, indicated a significant contribution of CDH23 variants to the non‑syndromic hearing loss in Chinese patients.

Sensorineural hearing loss (SNHL) is an increasingly prevalent sensory disorder, but the underlying mechanisms remain poorly understood. Adaptor related protein complex 2 subunit beta 1 (AP2B1) has been indicated to be detectable in mature cochleae. Nonetheless, it is unclear whether AP2B1 is implicated in the progression of SNHL.

Background: Noise-induced hearing loss (NIHL) is a kind of acquired sensorineural hearing loss and has shown an increasing incidence in recent years. Hence, elucidating the exact pathophysiological mechanisms and proposing effective treatment and prevention methods become the top priority. Though a great number of researches have been carried out on NIHL, few of them were focused on metabolites.

<b>Introduction:</b> In the course of middle ear diseases, a disturbed influence of the system transmitting sound through the middle ear on the function of the inner ear is observed. The audiometric consequence of the disease process taking place in the middle ear is the shift in bone conduction (BC) thresholds, which is called pseudoperceptive hearing loss (the so-called Carhart effect). The natural process of aging of the hearing system (age-related hearing loss) means that the manifestation of the Carhart effect varies in different age groups.
