Cystic fibrosis is a progressive‚ genetic disease that causes persistent lung infections and limits the ability to breathe over time. This condition leads to excessive production and accumulation of thick persistent mucus in the tracheobronchial tree. The mucous instead of normally being thin and slippery becomes so stiff and rigorous that adequate mucociliary clearance becomes almost impossible. Leading to mucus plugging in the bronchi and bronchioles. The cystic fibrosis foundations says: “In

Question number 1 The disease cystic fibrosis causes the buildup of salts to occur outside the cells of the tissue that lines human lungs. The salt draws in water‚ creating sticky‚ thick mucus that causes chronic breathing difficulties and eventually death. Which cell organelle is most likely defective in this case‚ and why? Solution According the medical experiment‚ cystic fibrosis disrupts the normal functioning of epithelial cells whose working is to make sweet glands in various parts of body

It is estimated that CF effects 30‚000 adults and children in the United States‚ with approximately 1‚000 new cases diagnosed each year. Cystic Fibrosis is most prevalent among white but affects all ethnic groups. Cystic Fibrosis results from an autosomal recessive gene mutation of the Cystic Fibrosis transmembrane

Christopher Smith Miss Chiu AP Bio CF Case Study March 19‚ 2015 Questions: 1. Currently‚ scientists believe that Cystic Fibrosis is caused by a defect in the CFTR gene causes cystic fibrosis (CF). This gene makes a protein that controls the movement of salt and water in and out of your body’s cells. In people who have CF‚ the gene makes a protein that doesn’t work well. This causes thick‚ sticky mucus and very salty sweat. Every person inherits two CFTR genes—one from each parent. Children

Cystic Fibrosis is caused by a fault in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on chromosome 7 at q31.2. For CF to be expressed‚ a faulty copy of the gene must be present at both alleles; autosomal recessive. Therefore both parents must be carriers of‚ or affected by the cystic fibrosis gene (fig. 1) for the gene to be passed on. If a person has one copy of the faulty allele (are heterozygous) they are carriers of the gene and can pass this allele on; if they possess

Cystic Fibrosis- Option 2 Justin Jang and Junior Suwannapeng Jasper High School Cystic fibrosis is an autosomal (not sex linked)‚ hereditary disease caused by a mutation in the gene called the cystic fibrosis transmembrane conductance regulator gene‚ or the CFTR gene. This CFTR gene belongs to a group of genes called ABC (ATP-binding cassette). These are transport molecules for molecules such as phosphate‚ glucose‚ chloride‚ and peptides. Specifically for the CFTR gene‚ the molecules transported

Cystic Fibrosis Cystic Fibrosis is caused by a single faulty gene that controls the movement of salt in the body. In people with Cystic Fibrosis‚ the internal organs become clogged with thick‚ sticky mucus resulting in infections and inflammation making it hard to breathe and digest food. For a baby to be born with Cystic Fibrosis‚ both parents must be carriers of the faulty CF gene. The diagram shows how CF is inherited. Where both parents carry the faulty gene‚ each child has a one in four chance

Jonathon discovers that he has the mutation responsible for the lethal disorder. Jonathon has worked as an air traffic controller and his company has learned of his results of his test‚ and as a result the company has dismissed Jonathan from his job where he had worked faithfully for more than eight years. Cystic Fibrosis is named because of the fibrous

Cystic Fibrosis: What is Cystic Fibrosis: Cystic fibrosis (CF) is a lifelong hereditary/genetic disorder‚ meaning the disease can be passed on from parent to child and can be inherited. CF is not contagious. Both parents must be either a carrier or suffer from CF for the disease to be passed on however carriers show no symptoms that a suffer does. CF affects the respiratory system; mainly the lungs and some parts of the digestive and reproductive systems including the pancreas‚ liver and the vas

Cystic Fibrosis‚ commonly known as CF‚ is a genetic disorder that causes the body to overproduce mucus. The overproduction of mucus affects many parts of the body. Primarily the lungs‚ pancreas‚ reproductive system‚ liver‚ sweat glands and intestines are all affected by the condition (Falvo 485). CF is most prevalent in Caucasians‚ but it also is seen in African Americans‚ Hispanics and Native Americans (“Cystic Fibrosis” 2012). Millions of people are carriers of the CF gene but in order for a
