Cerebral abnormalities in adults with ataxia-telangiectasia.
Ataxia-telangiectasia, an autosomal recessive disorder caused by defect of the ataxia-telangiectasia mutated gene, is characterized by progressive neurologic impairment with cerebellar atrophy, ocular and cutaneous telangiectasia, immunodeficiency, heightened sensitivity to ionizing radiation and susceptibility to developing lymphoreticular malignancy. Supratentorial brain abnormalities have be...
متن کاملAbnormalities in sensory and mixed evoked potentials in ataxia-telangiectasia.
Electromography, motor, sensory and mixed nerve conduction velocity, and H reflex were studied in four patients with ataxia-telangiectasia. The earliest and most striking electrophysiologial finding was the reduced amplitude of evoked nerve potentials. In the oldest patient, findings suggestive of spinal atrophy and mild reduction of the motor and sensory nerve conduction velocities were found....
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 کاملMyoclonus in Ataxia–Telangiectasia
BACKGROUND Various movement disorders can be found in ataxia-telangiectasia (AT), including ataxia, dystonia, chorea, and myoclonus, but myoclonus has rarely been described as the predominant feature in AT. CASE REPORT We report two AT patients with prominent myoclonus, illustrating an unusual presentation of this disorder. Sequencing of the ATM gene in the first patient revealed a homozygous...
