Several immunodeficiency-related genes have been identified and a large number of mutations in these genes. Currently, a genetic defect has been determined in more than 2000 patients. Only recently has it become possible to address structure-function effects of these mutations in the corresponding proteins. The consequences of mutations in structure are discussed for Btk in X-linked agammaglobulinemia (XLA), Jak3 in T-B+ severe combined immunodeficiency (SCID), p47phox and p67phox in autosomal chronic granulomatous disease (CGD) and SH2D1 A in X-linked lymphoproliferatine disease (XLP). The experimental and homology modelling derived structures were used to analyze mechanisms related to these diseases.
