The correct statement about cystic fibrosis is:
**Cystic fibrosis is caused by a deletion mutation.**
This is because cystic fibrosis is indeed caused by a specific type of genetic mutation known as a deletion, where three nucleotides (which code for one amino acid) are removed from the CFTR gene, leading to the production of a faulty protein. The other statements are inaccurate. Cystic fibrosis does have symptoms, affects both men and women, and there is a clear understanding of its genetic basis.
