Chronic granulomatous disease in an adult male: A proposed X-linked defect.
A 25-year old patient with chronic granulomatous disease of somewhat unusual history is described. The diagnosis of CGD was based on increased susceptibility to infection, granulomatous appearance of tissues, and diminished bactericidal and metabolic response of leukocytes during phagocytosis: the clinical and cellular features considered phenotypic of CGD. A 16-year-old female sibling had bactericidal and metabolic abnormalities of leukocyte function similar to those of the patient's leukocytes. Leukocytes from another sister, 26 years of age, were intermediate in bactericidal capacity. Two populations of leukocytes were identified by a histochemical test of NBT reduction. Both normal and abnormal polymorphonuclear leukocytes were present in the leukocyte population of the two sisters. Leukocytes from the patient's mother and maternal grandmother were normal by all methods tested. These findings are taken as evidence of a germ-line mutation in the chromosomal gene causing CGD, with transmission of the genetic defect from the mother to the son.
