CYBA (Cytochrome B-245 Alpha Chain) is a gene that encodes a crucial component of the NADPH oxidase complex, which allows immune cells—especially phagocytes—to produce reactive oxygen species (ROS). These ROS are vital for destroying invading pathogens. Mutations in CYBA can disrupt this defense mechanism, resulting in chronic granulomatous disease, a disorder characterized by recurrent infections.
