“…We looked at this question and confirmed Schier's findings (19). We then showed that anergy often progresses with progression of the disease (20), extends to a frequent deficiency in vigor of skin allograft rejections (21), and cannot readily be corrected by giving leukocytes from normal sensitive donors (5,15,19,(21)(22)(23) Before we studied the immune responses, immunoglobulin concentrations and lymphoid tissues of patients with ataxiatelangiectasia, this disease was considered primarily to be a neurological disorder (29)(30)(31). This disease, however, is featured by an association of progressive cerebellar ataxia, telangiectases of the sclera and skin, especially the skin of the eyelids, anticubital, and'popliteal regions.…”
