Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and chloride channel in vertebrates that is encoded by the CFTR gene.
Mutations of the CFTR gene affecting chloride ion channel function lead to dysregulation of epithelial fluid transport in the lung, pancreas and other organs, resulting in cystic fibrosis.

考題釋疑
囊性纖維化(Cystic fibrosis)為遺傳性疾病,主要是在第七對染色體長臂上(7q31)的囊性纖維化跨膜傳導調節(cystic fibrosis transmembrane conductance regulator)基因的缺陷,造成囊性纖維化跨膜傳導調節蛋白缺失,
