PURPOSE Usher syndrome type I (USH1) is an autosomal recessive disorder characterized by severe-profound sensorineural hearing loss, retinitis pigmentosa, and vestibular areflexia. To date, five USH1 genes have been identified. One of these genes is Usher syndrome 1C (USH1C), which encodes a protein, harmonin, containing PDZ domains. The aim of the present work was the mutation screening of the...
Despite the significant advances in understanding the molecular basis of hearing loss, precise identification of genetic cause still presents some difficulties, owing to pheno‐ typical variation. Gene discovery efforts for hearing disorders are complicated by ex‐ treme heterogeneity. Mutations in some of these genes, such as GJB2, MYO7A, CDH23, OTOF, SLC26A4, TMC1, are quite common and responsi...
BACKGROUND Despite current knowledge of mutations in 45 genes that can cause nonsyndromic sensorineural hearing loss (SNHL), no unified clinical test has been developed that can comprehensively detect mutations in multiple genes. We therefore designed Affymetrix resequencing microarrays capable of resequencing 13 genes mutated in SNHL (GJB2, GJB6, CDH23, KCNE1, KCNQ1, MYO7A, OTOF, PDS, MYO6, SL...
Usher syndrome (USH) is an autosomal recessive disorder characterized by combined deafness-blindness. It accounts for about 50% of all hereditary deafness blindness cases. Three clinical subtypes (USH1, USH2, and USH3) are described, of which USH1 is the most severe form, characterized by congenital profound deafness, constant vestibular dysfunction, and a prepubertal onset of retinitis pigment...
the incidence of pre-lingual hearing loss (hl) is about 1 in 1000 neonates. more than 60% of cases are inherited. non-syndromic hl (nshl) is extremely heterogeneous: more than 130 loci have been identified so far. the most common form of nshl is the autosomal recessive form (arnshl). in this study, a cohort of 36 big arnshl pedigrees with 4 or more patients from 7 provinces of iran was investig...
Inherited Retinal Dystrophies (IRDs) are a group of rare diseases with prevalence 1:3000-4000 people. They genetic, primarily affecting retinal photoreceptors and epithelial pigmentary cells, lead to neurodegeneration finally apoptosis. In 2021, we published our global results obtained in registry at the Fundación Jiménez Díaz University Hospital (Madrid, Spain) from 1991 August 2019. Now, aime...

زمینه و هدف: بروز ناشنوایی پیش از تکلم در نوزادان یک در هزار است که بیش از 60% موارد ارثی است. تقریبا 80% موارد ناشنوایی غیر سندرمی (nshl) می باشد. ناشنوایی غیر سندرمی بسیار هتروژن بوده و بیش از 100 لوکوس در آن شناخته شده که متداول ترین نوع آن مغلوب اتوزومی (arnshl) است. این مطالعه با هدف بررسی جهش های ژنی روی کانکسین 26 (gjb2) و کانکسین 30 (gjb6) و پیوستگی ژنتیکی سه لوکوس شایع ناشنوایی غیر سند...
BACKGROUND Genetic tests for hereditary hearing loss inform clinical management of patients and can provide the first step in the development of therapeutics. However, comprehensive genetic tests for deafness genes by Sanger sequencing is extremely expensive and time-consuming. Next-generation sequencing (NGS) technology is advantageous for genetic diagnosis of heterogeneous diseases that invol...
