Question

Cystic fibrosis is caused by
A. Recessive autosomal allele
B. Dominant autosomal allele
C. Recessive sex linked allele
D. Dominant sex linked allele

Answer 1

Cystic fibrosis (CF) can be stated as a hereditary condition that affects the lungs and gastrointestinal system. The body produces thick and sticky mucus that may clog the lungs and obstruct the pancreas.

Complete Answer:
CF may be stated as a congenital disease that mainly affects the lungs and gastrointestinal system, but it may result in fatal complications like disease and diabetes. The defective gene answerable for CF ends up in the creation of thicker, stickier mucus than is common. This mucus is difficult to spit up in the lungs. This makes breathing difficult and results in severe lung infections. The mucus interferes with pancreatic function by preventing enzymes from breaking down the food properly. Digestive problems result, potentially resulting in malnutrition. This thickening of mucus may cause male infertility by blocking the epithelial duct, or the tube that carries the sperm from the testes to the urethra. The most common explanation for death in people with CF is respiratory failure.

Symptoms of CF:
- Salty-tasting skin
- Persistent coughing
- Shortness of breath
- Wheezing
- Poor weight gain in spite of excessive appetite
- Greasy, bulky stools
- Nasal polyps, or small, fleshy growths found within the nose.

Treatment: There is currently no cure for CF. Treatment can manage the symptoms of the disease, however, and improve quality of life.
- Airway clearance: It is crucial for people with CF to induce mucus from their lungs to permit clear breathing and minimize lung infections. Airway clearance techniques (ACT) can help people with CF to loosen and obtain obviate mucus from their lungs.
- Inhaled medication is effective at reaching the airways and commonly used. The medications are often given by aerosol or as a metered dose inhaler. These medications can thin mucus, kill bacteria, and mobilize mucus to enhance airway clearance.
- Antibiotics are a crucial part of regular care. These may be taken orally, intravenously, or through inhalation. Other drugs, like ibuprofen and azithromycin, are found to preserve and improve lung function, and are now considered to be an element of ordinary therapy for people with CF, or through inhalation. Other drugs, like ibuprofen and azithromycin, are found to preserve and improve lung function, and are now considered to be a component of normal therapy for people with CF.

The correct option is A, recessive autosomal allele.

Note: People with CF may help reduce their risk of lung infection by taking the subsequent steps:
- Washing the hands frequently.
- Getting a flu shot once a year.
- Not smoking and avoiding second-hand smoke.
Avoiding unnecessary contact with people that have colds or other contagious illnesses.
