SUCLA2 is one of several nuclear-encoded genes that can cause encephalomyopathy accompanied by mitochondrial DNA depletion. The disorder usually manifests in early childhood and leads to early death. The gene encodes one of the subunits of succinyl-CoA synthase, the enzyme that catalyzes the reversible conversion of substrates succinyl-CoA and ADP to(More)
BACKGROUND Sandhoff disease is an autosomal recessive disorder caused by β-hexosaminidase deficiency and accumulation of GM2 ganglioside resulting in progressive motor neuron manifestations and death from respiratory failure and infections in infantiles. Pathogenic mutations in HEXB gene were observed which leads to enzyme activity reduction and(More)
Wiskott-Aldrich syndrome (WAS) is a life-threatening X-linked recessive immunodeficiency disease described as a clinical triad of thrombocytopenia, eczema, and recurrent infections, caused by mutations of the WAS protein (WASP) gene. The milder form of this disease is X-linked thrombocytopenia (XLT) that presents only as platelet abnormalities. Mutation(More)
OBJECTIVE To evaluate the mRNA expression ratio of Bcl-2/Bax both in normal and tumoral bladder tissues of patients with transitional cell carcinoma (TCC) of bladder and investigate potential correlation between this expression ratio and clinical outcome. MATERIALS AND METHODS In this experimental study, we used real time-PCR to investigate the expression(More)
Breast cancer is the most common malignancy among females in the world. In Iran, age and family history are the major risk factors for the development of this disease. Mutations of BRCA1 and BRCA2 genes are associated with a greatly increased risk for familial breast cancer. The frequency of BRCA mutations was identified in familial breast cancers (FBCs)(More)
PURPOSE To characterize mutations within the carbohydrate sulfotransferase 6 (CHST6) gene in Iranian subjects from 12 families with macular corneal dystrophy (MCD). METHODS Genomic DNA was extracted from peripheral blood of 20 affected patients and 60 healthy volunteers followed by polymerase chain reaction (PCR) and direct sequencing of the CHST6 coding(More)
Ataxia telangiectasia (AT) is an autosomal recessive multisystem disorder characterized by variable immunodeficiency, progressive neurodegeneration, occulocutaneous telangiectasia, and an increased susceptibility to malignancies. This study was designed to study the role of proapoptotic BAK, BAX, and NBK/BIK genes in a group of patients with AT to elucidate(More)
To evaluate five common cystic fibrosis trans-membrane conductance regulator (CFTR) mutations (ΔF508, G542X, R117H, W1282X and N1303K) in the Iranian infertile men with noncongenital absence of vas deferens (CAVD) obstructive azoospermia. The common CFTR gene mutations were tested on blood samples from 53 infertile men with non-CAVD obstructive azoospermia(More)
BACKGROUND/AIMS There is little data concerning the incidence of alpha-1-antitrypsin"(AAT) deficiency, the most common genetic cause of liver disease, among children with neonatal cholestasis in Iran. Thus, this study was performed to analyze AAT deficiency in this group of patients. MATERIALS AND METHODS DNA samples from patients with neonatal(More)
Background: Chronic obstructive pulmonary disease (COPD) is a major public health problem that needs greater attention. Variability in the susceptibility to develop COPD is related to both genetic and environmental factors. Oxidative stress and inflammation are the major hallmarks of COPD and antioxidant status can be used as a biomarker to assess the risk(More)
