An autosomal recessive inherited disorder characterized by choreoathetosis beginning in childhood, progressive cerebellar ataxia, telangiectasis of conjunctiva and skin, dysarthria, B- and T-cell immunodeficiency, and sensitivity to ionizing radiation. Affected individuals are prone to recurrent sinobronchopulmonary infections, lymphoreticular neoplasms, and other malignancies. Serum ALPHA-FETOPROTEINS are usually elevated.
