Additionally, our team includes members who have close friends affected by this condition, giving us a personal connection and a strong motivation to find a solution. By targeting the ΔF508 mutation, we aim to develop a therapy that could potentially, not only benefit many CF patients and make a significant improvement in their lives, but also can serve as a template, which research groups can use to target other genetic diseases. </p>
