title: [Genetic predisposition and susceptibility to mycobacterial infections: the IL-12-IFNgamma axis deficiency].
abstract: Since ten years severe pediatric infections which were idiopathic have now molecular explanation, defined new primary immunodeficiencies. These children presented a new kind of hereditary immunodeficiency with severe and/or recurrent infections caused by only one micro-organisms family. Some of these children have mycobacterial infections. Standard immunologic explorations were normal. However, they presented a vulnerability, sometimes lethal caused by Mycobacteria. The goal of this article is to describe the IL-12-IFNgamma axis deficiency (mendelian susceptibility to mycobacterial disease).
