YMDD motif mutations in chronic hepatitis B antiviral treatment naïve patients: a multi-center study
Background and Objective: Profound hearing loss is one of the most prevalent congenital disorders affecting about 1 in 1000 newborns. Autosomal recessive non-syndromic hearing loss (ARNSHL) is the predominant form of the severe inherited childhood deafness. This type of hearing loss in one-half of the cases is caused by mutations in GJB2 (connexin 26) and GJB6 (connexin 30) genes located at DFN...
β-thalassemia, a monogenic autosomal recessive disorder, is prevalent in middle east, particularly in iran. in iran, near to 20 mutations in the β-globin gene are introduced as common mutations with varying incidence frequencies in each city. therefore, detection and screening for couples at high risk can help to solve the problems of this disease. in this study, optimized genotyping of two com...
The reverse transcriptase V207I mutation within the hepatitis B virus (HBV) polymerase is associated with resistance to lamivudine in vitro. The prevalence of this mutation in treatment-naive patients was 1% (1/96). A follow-up of the patient carrying this mutation prior to treatment revealed no loss of sensitivity of HBV to lamivudine in vivo.
Background and Aim : Myeloproliferative neoplasms are clonal and heterogeneous disorders of hematopoietic stem cells lead to increase of one or more cell lines in the blood. Recently, the acquired mutation JAK2 V617F has been described in the majority of patients with myeloproliferative neoplasms (MPNs).This mutation is characterized by a G to T transverse at nucleotide 1849 in exon 12 of the J...
Abstract Background & Aims:BRAF-V600E mutation has recently been considered as a molecular marker in diagnosis of Hairy Cell Leukemia (HCL). Detection of this mutation has found a diagnostic and therapeutic value. The aim of the present study was comparing the diagnostic value of BRAF V600E mutation detection with other previous methods in diagnosis of HCL patients. Materials & M...
ObjectivesUndetectable or low-level hepatitis B virus (HBV) DNA and drug resistance mutations in patients may increase the risk of HBV transmission cause active viral replication other clinical problems. Here, we established a highly sensitive practical method for detection using polymerase chain reaction (PCR) -based CRISPR-Cas13a system (referred to as PCR-CRISPR) evaluated its capability sam...
Background: Hearing impairment as a heterogeneous disorder is the most common sensory defect that occur 1 in 1000. Mutations in GJB2 (CX26) gene at DFNB1 locus on 13q12 are responsible for autosomal recessive non-syndromic hearing loss (ARNSHL) in many populations. This study investigates the GJB2 gene mutations in deaf patients refereed to the deaf center of Tabriz. Methods: In the present ...
