A girl who has cystic fibrosis has moved into your neighbourhood. Without having met her, what do you know about her?

Question

Quizplus · Accepted Answer

Cystic fibrosis is caused by a mutation in both copies of the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. It is an autosomal recessive disorder, meaning that an individual must inherit two defective genes (one from each parent) to develop the condition. This implies that there was not a dominant, healthy gene to prevent the disease. The other options are incorrect or unrelated to cystic fibrosis.
