What is cystic fibrosis in biology?
Cystic fibrosis is an inherited disease characterized by the buildup of thick, sticky mucus that can damage many of the body’s organs. The disorder’s most common signs and symptoms include progressive damage to the respiratory system and chronic digestive system problems.
What is cystic fibrosis in simple words?
Cystic fibrosis (CF) is an inherited disease in which the body makes very thick, sticky mucus. The mucus causes problems in the lungs, pancreas, and other organs. People with cystic fibrosis (pronounced: SIS-tik fye-BROH-sis) get lung infections often.
How does cystic fibrosis happen?
Cystic fibrosis occurs when both genes in the pair have a mutation. A person with cystic fibrosis inherits one CF gene from each parent. Cystic fibrosis is a genetic disorder caused by inheriting a pair of genes that are mutated or not working properly.
What is cystic fibrosis mutation?
Summary. Cystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In people with CF, mutations in the CFTR gene can disrupt the normal production or functioning of the CFTR protein found in the cells of the lungs and other parts of the body …
What chromosome is cystic fibrosis on?
CF is caused by pathogenic mutations in a single large gene on chromosome 7 that encodes the cystic fibrosis transmembrane conductance regulator (CFTR) protein [4-9].
Why is it called cystic fibrosis?
It was first recognized as a specific disease by Dorothy Andersen in 1938, with descriptions that fit the condition occurring at least as far back as 1595. The name “cystic fibrosis” refers to the characteristic fibrosis and cysts that form within the pancreas.
How does cystic fibrosis affect the respiratory system?
The abnormal electrolyte transport system in CF causes the cells in the respiratory system, especially the lungs, to absorb too much sodium and water. This causes the normal thin secretions in the lungs to become very thick and hard to move. These thick secretions increase the risk for frequent respiratory infections.
What cells are involved in cystic fibrosis?
CF affects a cell protein called CFTR (cystic fibrosis transmembrane regulator). CFTR controls the flow of water and certain salts in and out of the body’s cells.
Why is cystic fibrosis recessive?
Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CFTR gene to have CF. If someone has a mutation in only one copy of the CFTR gene and the other copy is normal, he or she does not have CF and is a CF carrier. Carriers show no signs of the disease.
What type of mutation is cystic fibrosis?
Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CFTR gene to have CF. If someone has a mutation in only one copy of the CFTR gene and the other copy is normal, he or she does not have CF and is a CF carrier.
Is cystic fibrosis genetic or environmental?
Cystic fibrosis (CF) is a genetic disease. This means that it is inherited. A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier.
Is Cystic Fibrosis infectious?
Cystic fibrosis (CF) is the most common lethal genetic disease in the Caucasian population, and should be considered an infectious disease because of the basic pathophysiology.
What are facts about cystic fibrosis?
Cystic fibrosis (CF) is an inherited disease that causes the body to produce mucus that’s extremely thick and sticky. The mucus is thicker than normal because CF affects cells in the epithelium (pronounced: eh-puh-THEE-lee-um), the layer of cells that lines the passages in the body’s organs.
What are some interesting facts about cystic fibrosis?
Cystic fibrosis is an uncommon genetic disorder. It primarily affects the respiratory and digestive systems. Symptoms often include chronic cough, lung infections, and shortness of breath. Children with cystic fibrosis may also have trouble gaining weight and growing.
What does cystic fibrosis stand for?
Cystic fibrosis (CF) is a chronic, progressive, and frequently fatal genetic disease of the glands that produce or secrete sweat and mucus. CF primarily affects the respiratory, digestive, and reproductive tracts in children and young adults.
