T-cell immunodeficiencies.

Abstract

T-cell immune defects include most inherited immunodeficiencies diagnosed in childhood. Most cellular immunodeficiencies have associated humoral defects with variable clinical and laboratory features. The underlying gene defects are now known for most inherited T-cell immune defects, and mutation analysis is quickly becoming an integral part of evaluation and diagnosis. Detailed discussion of disease genotype-phenotype correlation with families is critical to medical management and long-term prognosis.
