The doctor says that Lydia’s baby has a disorder caused by one single gene. What does the baby MOST likely have?

Question

arthritis

cystic fibrosis

heart disease

diabetes

Answer 1

The baby most likely has cystic fibrosis. Cystic fibrosis is a disorder caused by a mutation in a single gene (the CFTR gene). In contrast, arthritis, heart disease, and diabetes are typically influenced by multiple genetic and environmental factors and are not caused by a single gene mutation.
