Molecular pathology of ataxia telangiectasia.
Ataxia telangiectasia (A-T) is one of a group of autosomal recessive cerebellar ataxias. Presentation is usually by the age of 2 years and ataxia of both upper and lower limbs develops, such that by early teenage most patients require a wheelchair for mobility. Speech and eye movement are also affected. Other important features are t(7;14) translocations, immunodeficiency, a high serum alpha fe...
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 ...
متن کاملAtaxia telangiectasia
Onset of the disease is often during the second year of life: there is progressive cerebellar ataxia (initially truncal, with further peripheral extend); ataxia is a constant feature in this disease; oculomotor apraxia, dysarthria, and dystonia; leading to muscular atrophia. Telangiectasia: facial region exposed to sunlight, and eyes (conjunctiva). Combined immunodeficiency (in 70 %): thymus hy...

Ataxia Telangiectasia (A-T) is an autosomal recessive hereditary progressive neurodegener‐ ative and multisystem disease characterized by cerebellar ataxia, telangiectasia, recurrent si‐ nopulmonary infections, variable immunologic defects among which a significantly higher incidence of leukaemia and lymphoma and type 2 diabete. This disorder has been clearly linked to the loss of expression of...
