Ella was born with cystic fibrosis, a genetic disease which has caused continuing lung infections all her life. When a targeted treatment became available for cystic fibrosis patients with certain genetic mutations (changes in their DNA), she had genetic testing to find out what her mutation is. Fortunately, Ella has been able to benefit from taking this new targeted therapy because it works for someone with her genetic mutation. She now shares information about how personalized medicine can develop new treatments to help others with cystic fibrosis.
