Chronic granulomatous disease (CGD) is an immunodeficiency disorder affecting about 1 in 250,000 individuals. The disease is caused by a lack of superoxide production by the leukocyte enzyme NADPH oxidase. Superoxide is used to kill phagocytosed micro-organisms in neutrophils, eosinophils, monocytes and macrophages. The leukocyte NADPH oxidase is composed of five subunits, of which the enzymatic component is gp91-phox, also called Nox2. This protein is encoded by the CYBB gene on the X chromosome. Mutations in this gene are found in about 70% of all CGD patients. This article lists all mutations identified in CYBB in the X-linked form of CGD. Moreover, apparently benign polymorphisms in CYBB are also given, which should facilitate the recognition of future disease-causing mutations.
慢性肉芽肿病(CGD)是一种免疫缺陷病,影响约二十五万人中的一人。该病是由白细胞酶 NADPH 氧化酶缺乏超氧化物产生引起的。超氧化物用于杀死中性粒细胞、嗜酸性粒细胞、单核细胞和巨噬细胞吞噬的微生物。白细胞 NADPH 氧化酶由五个亚基组成,其中酶成分是 gp91-phox,也称为 Nox2。该蛋白由 X 染色体上的 CYBB 基因编码。该基因的突变约见于所有 CGD 患者的 70%。本文列出了 X 连锁 CGD 中 CYBB 中已鉴定的所有突变。此外,还给出了 CYBB 中明显良性的多态性,这将有助于识别未来的致病突变。
