X-linked chronic granulomatous disease (CGDX) is a primary immunodeficiency characterized by onset of symptoms in the first months or years of life. Patients present with recurrent infections, lymphadenopathy, inflammatory bowel disease, granulomatous colitis, fever, skin infections, osteomyelitis, and/or abscesses. Infectious organisms usually include Staphylococcus aureus, Burkholderia cepacia, Serrata, Salmonella, mycobacteria, and fungi. The disorder results from impaired function of the phagocytic NADPH oxidase complex, which generates the microbiocidal respiratory burst. Laboratory studies using the DHR assay show impaired phagocytic production of reactive oxygen species in response to PMA stimulation (reviews by Dinauer et al., 2001 and Johnston, 2001; summary by Song et al., 2014). Genetic Heterogeneity of Chronic Granulomatous Disease Chronic granulomatous disease can be caused by mutation in several genes encoding structural or regulatory subunits of the phagocyte NADPH oxidase complex. See also CGD1 (233700), caused by mutation in the NCF1 gene (608512) on chromosome 7q11; CGD2 (233710), caused by mutation in the NCF2 gene (608515) on chromosome 1q25; CGD3 (613960), caused by mutation in the NCF4 gene (601488) on chromosome 22q13; CGD4 (233690), caused by mutation in the CYBA gene (608508) on chromosome 16q24; and CGD5 (618935) caused by mutation in the CYBC1 gene (618334) on chromosome 17q25. A similar syndrome, termed neutrophil immunodeficiency syndrome (608203), is caused by mutation in another protein involved in the NADPH oxidase complex, RAC2 (602049). Roos et al. (2021) provided a review of autosomal forms of chronic granulomatous disease.  http://www.omim.org/entry/306400

Chronic granulomatous disease is a disorder that causes the immune system to malfunction, resulting in a form of immunodeficiency. Immunodeficiencies are conditions in which the immune system is not able to protect the body from foreign invaders such as bacteria and fungi. Individuals with chronic granulomatous disease may have recurrent bacterial and fungal infections. People with this condition may also have areas of inflammation (granulomas) in various tissues that can result in damage to those tissues. The features of chronic granulomatous disease usually first appear in childhood, although some individuals do not show symptoms until later in life.

People with chronic granulomatous disease typically have at least one serious bacterial or fungal infection every 3 to 4 years. The lungs are the most frequent area of infection; pneumonia is a common feature of this condition. Individuals with chronic granulomatous disease may develop a type of fungal pneumonia, called mulch pneumonitis, which causes fever and shortness of breath after exposure to decaying organic materials such as mulch, hay, or dead leaves. Exposure to these organic materials and the numerous fungi involved in their decomposition causes people with chronic granulomatous disease to develop fungal infections in their lungs. Other common areas of infection in people with chronic granulomatous disease include the skin, liver, and lymph nodes.

Inflammation can occur in many different areas of the body in people with chronic granulomatous disease. Most commonly, granulomas occur in the gastrointestinal tract and the genitourinary tract. In many cases the intestinal wall is inflamed, causing a form of inflammatory bowel disease that varies in severity but can lead to stomach pain, diarrhea, bloody stool, nausea, and vomiting. Other common areas of inflammation in people with chronic granulomatous disease include the stomach, colon, and rectum, as well as the mouth, throat, and skin. Additionally, granulomas within the gastrointestinal tract can lead to tissue breakdown and pus production (abscesses). Inflammation in the stomach can prevent food from passing through to the intestines (gastric outlet obstruction), leading to an inability to digest food. These digestive problems cause vomiting after eating and weight loss. In the genitourinary tract, inflammation can occur in the kidneys and bladder. Inflammation of the lymph nodes (lymphadenitis) and bone marrow (osteomyelitis), which both produce immune cells, can lead to further impairment of the immune system.

Rarely, people with chronic granulomatous disease develop autoimmune disorders, which occur when the immune system malfunctions and attacks the body's own tissues and organs.

Repeated episodes of infection and inflammation reduce the life expectancy of individuals with chronic granulomatous disease; however, with treatment, most affected individuals live into mid- to late adulthood.  https://medlineplus.gov/genetics/condition/chronic-granulomatous-disease
