The CFTR gene, when mutated, is primarily associated with cystic fibrosis, a condition that affects the lungs and digestive system. A) Some individuals with a mutation in one copy of the CFTR gene (carriers) may not show any symptoms, hence a child could potentially develop normally without clinical manifestations. B) Severe cases of cystic fibrosis can lead to lung damage requiring a lung transplant. E) It's also possible for a child to exhibit mild signs and symptoms of cystic fibrosis, depending on the specific mutation and other genetic or environmental factors. C) and D) are incorrect because cystic fibrosis does not necessitate bilateral mastectomies nor does it increase the risk of developing Alzheimer's disease.
