Chronic granulomatous disease (CGD) is a rare inherited immunodeficiency disorder. The clinical presentation is varied depending on the degree of involvement of the NADPH oxidase system responsible for the oxidative burst of neutrophils. We present 3 cases of variant X-linked CGD in an effort to introduce the disease and highlight the importance and limitations of CGD screening. The variant X-linked form of CGD results in a less severe phenotype and frequently presents later in life. Variant X-linked CGD is difficult to diagnose, but is becoming more readily recognized based on improved testing methods. A high index of suspicion in the setting of unusual infections such as Burkholderia cepacia pneumonia is essential to make the diagnosis. Family screening can lead to early intervention, prophylaxis, and appropriate genetic counseling.
