Case scenario

Luke is a 7-year-old boy whose father is known to carry the common cystic fibrosis (CF) gene mutation p.F508del (formerly ΔF508). Two of his father’s four siblings died from CF at an early age. Luke’s mother is negative for p.F508del and does not carry any of the seven other most common CF gene mutations.
