What genetic disorder is characterized by difficulty breathing and recurrent lung infections?

• A. Cystic Fibrosis
• B. Huntington's Disease
• C. Sickle Cell Anemia
• D. Down's Syndrome

Answer: (A)

Cystic fibrosis is the correct answer because it is a genetic disorder that significantly impacts the respiratory system. This condition affects the cells that produce mucus, leading to the production of thick, sticky mucus that clogs the airways and makes it difficult to breathe. This increased mucus can also trap bacteria and lead to frequent lung infections, contributing to the respiratory complications often associated with the disorder. In contrast, Huntington's disease primarily affects neurological function, leading to cognitive decline and movement disorders, not respiratory issues. Sickle cell anemia is a blood disorder that can cause pain and organ damage, but it is not directly associated with respiratory problems. Down's syndrome, caused by an extra chromosome 21, can lead to a variety of health issues, but it does not specifically manifest as difficulty breathing or recurrent lung infections. Thus, when considering the specific symptoms mentioned, cystic fibrosis emerges as the clear connection.
