Oxidative stress in ataxia telangiectasia.
Ataxia telangiectasia is one of a group of recessive hereditary genomic instability disorders and is characterized by progressive neurodegeneration, immunodeficiency and cancer susceptibility. Heterozygotes for the mutated gene are more susceptible to cancer and to ischaemic heart disease. The affected gene, ATM (ataxia telangiectasia mutated), has been cloned and codes for a protein kinase (AT...
متن کاملChromosome Instability and Oxidative Stress Markers in Patients with Ataxia Telangiectasia and Their Parents
Ataxia telangiectasia (AT) is a rare neurodegenerative disorder, inherited in an autosomal recessive manner. Total blood samples were collected from 20 patients with AT, 13 parents of patients, and 17 healthy volunteers. This study aimed at evaluating the frequency of chromosomal breaks in spontaneous cultures, induced by bleomycin and ionizing radiation, and further evaluated the rates of oxid...
متن کاملOxidative stress, mitochondrial abnormalities and antioxidant defense in Ataxia-telangiectasia, Bloom syndrome and Nijmegen breakage syndrome
Rare pleiotropic genetic disorders, Ataxia-telangiectasia (A-T), Bloom syndrome (BS) and Nijmegen breakage syndrome (NBS) are characterised by immunodeficiency, extreme radiosensitivity, higher cancer susceptibility, premature aging, neurodegeneration and insulin resistance. Some of these functional abnormalities can be explained by aberrant DNA damage response and chromosomal instability. It h...
متن کاملAtaxia-telangiectasia
Objective Ataxia-telangiectasia (AT) is a rare, severe, and ineluctably progressive multisystemic neurodegenerative disease. Variant AT phenotypes have been described in patients with mildand late-onset neurologic deterioration and atypical features (dystonia and myoclonus). We report on the clinical characteristics and transcriptome profile of patients with a typical AT presentation and genoty...
متن کاملAtaxia-telangiectasia.
Ataxia-telangiectasia is a complex syndrome that includes a very high cancer risk in children with a progressive cerebellar ataxia, the onset of which occurs in early infancy. Ocular telangiectasiae often do not appear until several years after the ataxia. The most common type of malignancy is lymphoma, usually of the B-cell type. Leukemias also occur. Failure to diagnose ataxia-telangiectasia ...
