Both of the human genes involved have been cloned and gene therapy is of potential use in the treatment of both diseases. Cystic fibrosis is due to a mutation in a gene that codes for a chloride channel protein in the cell membranes of epithelial cells. This protein regulates the secretion of chloride ions from the epithelial cells. If the
