[ 1 ] - شیوع جهش‌های ژن SLC26A4 در ناحیه‌ی کروموزومی DFNB4 در جمعیت ناشنوای ارثی ایران
مقدمه: جهش در ژن SLC26A4 که در جایگاه کروموزومی DFNB4 قرار دارد، سبب ایجاد کاهش شنوایی ارثی به طور غیرسندرمی و سندرمی (سندرم پندرد) می‌شود. در جمعیت‌های زیادی جهش این ژن به عنوان دومین عامل ناشنوایی ارثی گزارش شده است. هدف از این مطالعه بررسی شیوع جهش‌های ژن SLC26A4 در خانواده‌های مبتلا به ناشنوایی سندرمی(سندرم پندرد) و غیرسندرمی در ناشنوایان جسمی مغلوب همراه با کاهش شنوایی ارثی بود. مواد و روش...
[ 2 ] - Novel CFTR Mutations in Two Iranian Families with Severe Cystic Fibrosis
Background: Cystic fibrosis (CF) is a common autosomal recessive disorder that affects many body systems and is produced by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. CF is also the most frequently inherited disorder in the West. The aim of this study was to detect the mutations in the CFTR gene in two Iranian families with CF. Methods: After DNA extractio...
[ 3 ] - Investigating Seven Recently Identified Genes in 100 Iranian Families with Autosomal Recessive Non-syndromic Hearing Loss
Objectives: Hearing loss (HL) is the most common sensory disorder, and affects 1 in 1000 newborns. About 50% of HL is due to genetics and 70% of them are non-syndromic with a recessive pattern of inheritance. Up to now, more than 50 genes have been detected which are responsible for autosomal recessive non-syndromic hearing loss, (ARNSHL). In Iran, HL is one of the most common disabilitie...
[ 4 ] - The Effect of Xmn1 Gene Polymorphism on Blood Transfusion Dependency and Hemoglobin Concentration among Iranian Thalassemia Patients with IVSII-1 Mutation
Background: One of the most important phenotypic modifying factors for thalassemia is the presence of Xmn1 polymorphism. This retrospective study was performed to investigate the overall prevalence of Xmn1 polymorphism among Iranian β-thalassemia patients with homozygote IVSII-1mutation and to assess the relationship between Xmn1 polymorphism with patients’ hemoglobin levels and the response to...
[ 5 ] - Clinical and Genetic Characteristics of Splicing Variant in CYP27A1 in an Iranian Family with Cerebrotendinous xanthomatosis
Cerebrotendinous xanthomatosis (CTX) is a rare inborn lipid-storage disease leading to a progressive multisystem disease. CTX with autosomal recessive inheritance is caused by a defect in the CYP27A1 gene. Hallmark clinical manifestations of CTX include bilateral cataracts, chronic diarrhea, tendon xanthomas, and neurologic dysfunction. CTX is a rare disorder, which is supposed to be under-diag...
[ 6 ] - Genetic Causes of Putative Autosomal Recessive Intellectual Disability Cases in Hamedan Province
Objective: The aim of this study was to investigate the genetic causes of autosomal recessive intellectual disabilities (AR-ID) in Hamadan province of Iran. Materials & Methods: In this descriptive-analytical cross-sectional study, 25 families with more than one affected with putative autosomal recessive intellectual disability were chosen with collaboration of Welfare Organization of Hamada...
