objective: this study was designed to investigate rbc indices and hba2 levels in parents of major beta-thalassemia patients to detect possible silent beta- thalassemia carriers and examine its potential impact on the premarital genetic counseling. materials and methods: this cross sectional study was performed at children medical center from 2004 to 2006. after genetic counseling and getting in...
background: for screening sequence variations in genes, rapid turnover time is of fundamental importance. while, many of the current methods are unfortunately time consuming and technically difficult to implement. denaturing high-performance liquid chromatography (dhplc) method had been shown to be a high-throughput, time saving, and economical tool for mutation screening. objective: in the pre...
Introduction: Cleft lips and cleft palates are common congenital abnormalities in children. Various chromosomal loci have been suggested to be responsible the development of these abnormalities. The present study was carried out to investigate the association between the suspected genes (methylenetetrahydrofolate reductase [MTHFR] A1298C and C677T) that might contribute into the etiology of the...
jak2 is a tyrosine kinase that plays an important role in the signaling pathways of many hematopoietic growth factor receptors. a single acquired point mutation – v617f – in jak2 occurs in the great majority of patients with polycythemia vera (pv) and approximately half of the patients with idiopathic myelofibrosis (imf) or essential thrombocythemia (et). in contrast, the jak2-v617f mutation is...
Background & Aims: Genetic mutation, 1691G> A common polymorphism in a gene that is inherited coagulation Factor 5 is associated with increased risk of thrombosis. This mutation in different populations can develop in the prognosis of thrombotic disorders, cardiovascular disorders recurrent miscarriage and other thrombotic factors are useful. Study using appropriate strategies such as review o...
MeduIIary thyroid carcinoma (MTC) occurs both sporadically and in the autosomal dominantly inherited multiple endocrine neoplasia (MEN) type 2 syndromes. The distinction between true sporadic MTC and a new mutation familial case is important for future clinical management of both the patient and family. The susceptibility gene for hereditary MTC is the RET proto-oncogene. DNA analysis for g...
Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...
Background and Objective: Mutations in GJB2 gene is the most common cause of autosomal recessive non-syndromic hearing loss in many populations. The aim of this study was to determine the frequency of 35delG, 167delT, M34T, 235delC mutations in West Azarbaijan population. Materials and Methods: 129 patients from 96 families were studied. Mutations were detected using ASO-PCR and PCR-RFLP method...
Background: Congenital hearing loss due to different genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2 (Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...
Background and purpose: Chemokines and their receptors are expressed in different types of malignancies. CC chemokines MIP-1a (CCL3), MIP-1b (CCL4) and RANTES (CCL5) is believed to be anti-tumor and also aid to the metastasis in tumor microenvironment. CCR2 and CCR5 are special G-protein receptors for these chemokines. Due to the important role of CCR5 chemokine receptor in tumor biology, this ...
