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...
روش بررسی: در این مطالعه ی توصیفی-آزمایشگاهی به شناسایی جهش در اگزون های 1، 2، 3، 5 و 8 ژن lrtomt در 157 بیمار پرداخته شد. dna از نمونه های خونی تمام بیماران به روش استاندارد فنل- کلروفرم استخراج شد. اگزون های مورد بررسی توسط واکنش زنجیره ای پلیمراز (pcr) تکثیر شدند. سپس جهش های ژن lrtomt با استفاده از روش pcr-sscp برای 5 اگزون، مورد بررسی قرار گرفتند. به علاوه، تمام نمونه ها بوسیله ی آنالیز ه...
مقدمه: ناشنوایی یک اختلال حسی- عصبی است و یکی از شایع ترین نقص های مادرزادی می باشد که دارای بروز یک در هزار در بین نوزادان می باشد. مطالعات نشان داده است که پنجاه درصد موارد ناشنوایی، دارای علل ژنتیک و پنجاه درصد باقی مانده، دارای علل محیطی و ناشناخته است؛ قابل ذکر است که این نقص، بسیار ناهمگن می باشد. ناشنوایی در حدود 70 درصد موارد، غیرسندرمی است و تنها نقص موجود در بیمار می باشد؛ حدود 80 درص...
hearing loss (hl) is the most frequent sensory defect affecting 1 in 1000 neonates. this can occur due to genetic or environmental causes or both. the genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (arnshl). the aim of this study was to determine the contribution of the lrtomt gene mutations in causing arnshl...
BACKGROUND Hearing loss (HL) is the most frequent sensory birth defect in humans. Autosomal recessive non-syndromic HL (ARNSHL) is the most common type of hereditary HL. It is extremely heterogeneous and over 70 loci (known as DFNB) have been identified. This study was launched to determine the relative contribution of more frequent loci in a cohort of ARNSHL families. METHODS Thirty-seven Ir...
