BACKGROUND Non-syndromic hearing loss (NSHL) is the most common birth defect and occurs in approximately 1/1,000 newborns. NSHL is a heterogeneous trait and can arise due to both genetic and environmental factors. Mutations of the transmembrane channel-like 1 (TMC1) gene cause non-syndromic deafness in humans and mice. OBJECTIVES The aim of the present study was to investigate the association...
Hereditary nonsyndromic hearing loss is extremely heterogeneous. Mutations in the transmembrane channel-like gene1 (TMC1) are known to cause autosomal dominant and recessive forms of nonsyndromic hearing loss linked to the loci of DFNA36 and DFNB7/11, respectively. We characterized a six-generation Chinese family (5315) with progressive, postlingual autosomal dominant nonsyndromic hearing loss ...
The tip link protein protocadherin 15 (PCDH15) is a central component of the mechanotransduction complex in auditory and vestibular hair cells. PCDH15 is hypothesized to relay external forces to the mechanically gated channel located near its cytoplasmic C terminus. How PCDH15 is coupled to the transduction machinery is not clear. Using a membrane-based two-hybrid screen to identify proteins th...
Epstein-Barr nuclear antigen 1 (EBNA-1) is consistently expressed in all EBV-associated gastric carcinomas. We explored its biological effects in gastric carcinoma cells by expressing the protein in two Epstein-Barr virus (EBV)-negative gastric carcinoma cell lines (SCM1 and TMC1). EBNA1-expressing SCM1 and TMC1 cells displayed no significant differences in growth rates, respectively, compared ...
Transmembrane O-methyltransferase (TOMT/LRTOMT) is responsible for non-syndromic deafness DFNB63. However, the specific defects that lead to hearing loss have not been described. Using a zebrafish model of DFNB63, we show that the auditory and vestibular phenotypes are due to a lack of mechanotransduction (MET) in Tomt-deficient hair cells. GFP-tagged Tomt is enriched in the Golgi of hair cells...
ناشنوایی شایع ترین نقص حسی- عصبی در انسان است که بسیار هتروژن بوده و عوامل ژنتیکی، محیطی یا هر دو در بروز آن دخیل میباشد. بیش از50 درصد علل ناشنوایی به عوامل ژنتیکی نسبت داده شدهاند. مطالعات متعدد تاثیر منفی مداوم ناشنوایی را در ارتباطات و کیفیت زندگی فرد نشان دادهاند. بنابراین اقدام در راستای بهینهسازی عملکرد و حفظ یا بهبود شنوایی امری لازم و ضروری به نظر میرسد. در این جهت، پس از ارزیابی ...
Mutations in the autosomal genes TMPRSS3, TMC1, USHIC, CDH23 and TMIE are known to cause hereditary hearing loss. To study the contribution of these genes to autosomal recessive, non-syndromic hearing loss (ARNSHL) in India, we examined 374 families with the disorder to identify potential mutations. We found four mutations in TMPRSS3, eight in TMC1, ten in USHIC, eight in CDH23 and three in TMI...
conclusions more studies are needed to investigate the relationship between other parts of this gene with hearing loss in different populations through the country. more research could clarify the role of this gene and its relation with deafness and provide essential information for the prevention and management of auditory disorders caused by genetic factors in the iranian population. backgrou...
