CYBA (Cytochrome B-245 Alpha Chain): CYBA is an integral part of the NADPH oxidase complex, a key enzyme system in immune cells, especially phagocytes, for generating reactive oxygen species (ROS). These ROS are crucial for the immune system's defense mechanism against pathogens. CYBA mutations can lead to chronic granulomatous disease, a condition characterized by recurrent bacterial and fungal infections due to the inability of phagocytes to produce bactericidal ROS. Understanding CYBA's role is essential in managing and treating this immune deficiency....
