Discovery of 105 additional genetic errors that cause cystic fibrosis

Of the over 1,900 errors already reported in the gene responsible for cystic fibrosis (CF), it is unclear how many of them actually contribute to the inherited disease. Now a team of researchers reports significant headway in figuring out which mutations are benign and which are deleterious. In so doing, they have increased the number of known CF-causing mutations from 22 to 127, accounting for 95 percent of the variations found in patients with CF...
