Answer 1

The baby most likely has cystic fibrosis. Cystic fibrosis is a genetic disorder caused by mutations in a single gene (the CFTR gene). The other conditions listed (arthritis, heart disease, and diabetes) are not typically caused by mutations in a single gene and can result from a combination of genetic and environmental factors.
