Ataxia telangiectasia is a rare autosomal recessive multisystem disorder,having an incidence of 1:40,000 to 1:100,000 with an equal ratio in males and females, characterized by cerebellar ataxia, variable immunodeficiency, oculocutaneous telangiectasia, increased x ray hypersensitivity and susceptibility to malignancies. The causative gene has been localized to chromosome 11q22-23. Here a case ...

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 is known for cerebellar degeneration, but clinical descriptions of abnormal tone, posture, and movements suggest involvement of the network between cerebellum and basal ganglia. We quantitatively assessed the nature of upper-limb movement disorders in ataxia-telangiectasia. We used a three-axis accelerometer to assess the natural history and severity of abnormal upper-limb...
