Non randomised pilot descriptive multicentric study. Since recently it has been shown that Nox2p22phox protein is expressed not only in phagocytic cells but also in non-phagocytic cells such as fibroblasts, epithelial cells ,vascular cells, neurons. If pathological consequences of the deficiency Nox2 and p22phox, essential to the production of bactericidal toxic derivatives at the level of phagocytic cells, is well documented, impact of their absence in other types of non-phagocytic cells is not known. A better understanding of the impact of the absence of these proteins in these tissues could improve the management of CGD patients by providing a more specific monitoring of their condition. Similarly the formation of different cell models of all genetic forms of CGD that do not exist at present will be of great use to study the physiopathology of this disease and as tools for future studies.
