A great advantage made possible by the cloning of the CF gene has been the ability to use gene targeting to "knock out" the cf gene in mice, or to produce mice homozygous for the D F508-CFTR mutation or G551D mutation . The phenotypes of these mice are examined closely in later chapters. For now, two generalizations seem to hold. First, if a small amount of natural CFTR escapes the targeted disruption, the mice are almost normal , and second, there is very little difference so far between null mice and mice with the D F508-CFTR mutation. Finally, and of great interest, is the finding that mice bred into certain backgrounds actually develop lung disease.
