Recessive mutations in the SLC26A4 gene are responsible for nonsyndromic enlarged vestibular aqueduct (EVA) and Pendred syndrome. However, in some affected families, only 1 or 0 mutated allele can be identified, as well as no clear correlation between SLC26A4 genotypes and clinical phenotypes, hampering the accuracy of genetic counseling. To elucidate the(More)
Mutations in the OTOF gene have been found to be common causes of auditory neuropathy (AN) in Caucasians. However, the prevalence and spectrum of OTOF mutations in other populations have been inadequately documented. To explore the genetic characteristics of East Asian patients with AN, we screened for mutations in the OTOF gene by direct sequencing in 22(More)
Recessive mutations in the SLC26A4 gene are a common cause of hereditary hearing impairment worldwide. Previous studies have demonstrated that different SLC26A4 mutations may have different pathogenetic mechanisms. In the present study, we established a knock-in mouse model (i.e., Slc26a4(tm1Dontuh/tm1Dontuh) mice) homozygous for the c.919-2A>G mutation,(More)
Accurate epidemiological data on common deafness genes are essential to improve the efficiency and to reduce the cost of molecular diagnosis. They may depend on several factors, including a clear delineation of the source of patients being studied. In the present study, we hypothesize that patients with idiopathic sensorineural hearing loss recruited from(More)
Despite the clinical utility of genetic diagnosis to address idiopathic sensorineural hearing impairment (SNHI), the current strategy for screening mutations via Sanger sequencing suffers from the limitation that only a limited number of DNA fragments associated with common deafness mutations can be genotyped. Consequently, a definitive genetic diagnosis(More)
Mutations in the SLC26A4 gene are a common cause of human hereditary hearing impairment worldwide. Previous studies have demonstrated that different SLC26A4 mutations have different pathogenetic mechanisms. By using a genotype-driven approach, we established a knock-in mouse model (i.e., Slc26a4(tm2Dontuh/tm2Dontuh) mice) homozygous for the common p.H723R(More)
Age-related hearing impairment (ARHI) is a complex neurodegenerative disorder caused by a combination of environmental and genetic factors. We have reported previously that obesity increases the risk for ARHI, and that plasma levels of adiponectin are associated with ARHI. In the present study, we further explored the role of adiponectin in the(More)
