CDiReC - Chronic Granulomatous Disease (CGD) Diagnosis and Research Center
HISTORY OF CGD DISCOVERY
CGD (Chronic Granulomatous Disease) is due to a defect in the NADPH oxidase complex.
The active complex assembles from membrane components (Nox2/p22phox) and cytosolic components (p47phox=NCF1, p67phox=NCF2).
Other components (p40phox=NCF4) and the small G protein Rac2 are not associated so far with cases of CGD.
