Overcoming the burden of cystic fibrosis

Effective modulator treatments now available for most people will probably add years to their lives

The report by Lin and colleagues in this issue of the Journal on cystic fibrosis diagnosed during adulthood1 is a timely reminder of the importance of the disorder. More than 4000 people in Australia have cystic fibrosis,2 and one in 25 carry disease‐relevant gene mutations.3 Further, despite routine screening of newborns, clinical diagnosis remains important, and late diagnosis is associated with lower life expectancy.4 Finally, new therapies that target its genetic bases substantially improve outcomes for patients.5
