Heterogeneity of the immunological deficiency in ataxia-telangiectasia: absence of a clinical-pathological correlation.

We have been impressed by the absence of severe and recurring infections in most of our patients with ataxia-telangiectasia. In this report, our clinical and laboratory data on 25 patients are reviewed. We found a heterogeneity of immunological results and a lack of correlation between these results and clinical well-being.
