What is the difference between cystic fibrosis and multiple sclerosis?

Cystic fibrosis (CF) is a genetic disorder caused by mutations in the CFTR gene, leading to thick mucus production that affects the lungs and digestive system, primarily impacting respiratory function and nutrient absorption. In contrast, multiple sclerosis (MS) is an autoimmune disease where the immune system attacks the protective myelin sheath of nerve fibers in the central nervous system, leading to neurological symptoms such as muscle weakness, coordination issues, and vision problems. While CF is inherited and primarily affects the lungs and pancreas, MS is acquired and primarily impacts the nervous system.
