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)
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)
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)
BACKGROUND According to the theory of mitochondrial aging, oxidative stress plays a major role in aging and age related degenerative diseases. Since oxygen consumption and reactive oxygen species rate increase during aerobic exercise, we hypothesised that heavy aerobic training could lead to enhanced mitochondrial DNA (mtDNA) deletion in postmitotic(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)
INTRODUCTION 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(More)
PURPOSE 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. METHODS The common CFTR gene mutations were tested on blood samples from 53 infertile men with non-CAVD(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 Leber hereditary optic neuropathy (LHON) is an inherited form of bilateral optic atrophy leading to the loss of central vision. The primary cause of vision loss is mutation in the mitochondrial DNA (mtDNA), however, unknown secondary genetic and/or epigenetic risk factors are suggested to influence its neuropathology. In this study folate gene(More)
