Obstructive Lung Disease: Cystic Fibrosis

The type of mutation that causes Cystic Fibrosis occurs in the CFTR gene, or Cystic Fibrosis Transmembrane Conductance Regulator gene. This gene is important to the body because it helps provide channels that transport negatively charged particles (chloride ions) in and out of the cell. Chloride has an important role in the human body by how it controls the movement of water in tissue, which allows mucus to become thin. Mutations in the CFTR gene interrupts the function of the chloride channels. It makes the regulating process of the flow of chloride ions and water across the cell membranes not happen. This causes passageways to produce mucus that is very thick. The thick mucus causes these passageways to clog, and trap

Cystic Fibrosis (CF) is a disorder causing the body to release extremely thick and sticky mucus that clogs the lungs and pancreas, leading to problems with breathing and digestion, infection, and ultimately death. Abnormal secretion of sweat and saliva glands is also characteristic of CF. This disease a hereditary disorder of the exocrine glands that is characterized by respiratory and digestive problems and the most common inherited disease among Caucasians, affecting 3,600 live births in the Canada alone. CF affects men and women equally, but affects white people more than black people. This disease mainly affects children and young adults and is diagnosed by the age of three. Due to the advances in genetic research, diagnosis has been

Cystic Fibrosis is an inherited disease caused by mutations in a gene on 7th pair of chromosomes. Cystic Fibrosis is a chromosomal abnormality, meaning that one of the 23 pairs of chromosomes are not what they are supposed to be. A person without Cystic Fibrosis has a gene in chromosome 7, which produces a normal and substantial amount of protein called Cystic Fibrosis transmembrane regulator (CFTR), which in turn produces thin and watery mucus. A person with Cystic Fibrosis has a gene in chromosome 7, which produces either abnormal CFTR protein or no CFTR protein at all, which causes the body to produce thick and sticky mucus “A person with CF produces abnormal CFTR protein — or no CFTR protein at all, which causes the body to make thick,

Cystic Fibrosis (CF) also knows as (mucoviscidosis) is a single-gene disorders. This disorder is best described as an autosomal recessive of the exocrine glands. The disorder itself can be categorized as either pus- forming or hindering airflow. The responsible gene for this pulmonary disorder has been discovered to the be on the long part of the arm of chromosome 7 (Copstead & Banasik, 2013). Major signs and symptoms of CF will be associated with the gastrointestinal and respiratory system. We are able to diagnose CF though laboratory testing such as arterial blood measurements. Treatments for CF tend to be comprehensive including specialty physicians, nutritionists, physical and respiratory therapists and genetic counselors. Medicare

What is Cystic Fibrosis? Dr. Polit describes Cystic Fibrosis, also referred to as CF, the most common fatal recessive genetic disease among white people. It is a hereditary disorder, also known as mucoviscidosis, which disturbs the lungs, as well as the digestive system, by blockage due to the creation of abnormally thick mucus. According to the U.S. National Library of Medicine, “This abnormal mucus can clog the airways, leading to severe problems with breathing and bacterial infections in the lungs. These infections cause chronic coughing, wheezing, and inflammation”. Due to the buildup and infections, scar tissue forms as well as lung cysts causing permanent lung damage. It is also very common for those with cystic fibrosis to suffer from digestive problems because of the blockages caused by thick, sticky mucus in the body.

Cystic Fibrosis is caused by a genetic defect in Chromosome 7. Chromosome 7 encodes the cystic fibrosis transmembrane conductance regulator, also known as CFTR. There are over 1,000 mutations of this gene causing cystic fibrosis, with each mutation manifesting as a different variation of disease onset and clinical presentation. The most common mutation is the loss of phenylalanine residue at deltaF508. The abnormal functioning CFTR causes impaired chloride transport and more viscous secretions. The defect causes dehydrated secretions in the respiratory tract and gastrointestinal tract. Being dehydrated, these secretions become more difficult to move throughout the body. Along with impaired mucociliary clearance, this leads to chronic infection and inflammation, which in turn leads to more impaired mucociliary clearance. It unfortunately becomes an endless

Cystic fibrosis is an inherited life- threatening disorder that damages the lungs and digestive system. This disorder can also be known as Mucoviscidosis . Long- term issues include difficulty breathing, also coughing up sputum as a result from frequent lung infections. Sinus infections, poor growth, clubbing of the finger and toes, also infertility in men are other possible symptoms of this disorder. Different individuals may have different degrees of symptoms. Cystic fibrosis is an autosomal recessive disorder. Mutations in both copies of the gene for the protein cystic fibrosis transmembrane conductance regulatory (CFTR) is the cause of this. CFTR is involved in production of sweat, digestive fluids, and mucus. Secretions,

Cystic fibrosis, a genetic disorder, is currently affecting more than 30,000 people in the United States (About). According to “What is a Genetic Disorder?” (2014) “A genetic disorder is a disease that is caused by a change, or mutation, in an individual’s DNA sequence.” Cystic Fibrosis is an uncommon but serious disorder that causes consistent lung infections and limits the ability to breathe overtime. It affects the exocrine glands, which play a crucial role in regulating body temperature by producing sweat and many substances. It causes unusual heavy mucus, leading to blockage in the pancreatic ducts, intestines, bronchi, resulting in respiratory infection (About). Cystic fibrosis affects many people, and it has a specific mode of inheritance,

The gene that’s responsible for causing Cystic Fibrosis is on chromosome 7. The most common

Cystic fibrosis is a disorder affecting approximately 30,000 U.S. citizens. Although this genetic disorder can affect anyone, whites tend to be at a greater risk of developing this disease. Also males and females seem to have an equal risk of developing cystic fibrosis (Gardner, 2007). Cystic fibrosis is passed onto offspring by a recessive mode of inheritance. After extensive analysis it is believed that there is a single cystic fibrosis locus located on human chromosome seven. Considering a multitude of data and factors such as tissue specificity and the predicted properties of the Cystic Fibrosis Transmembrane Conductance Regulator(CFTR) protein, it is theorized that CFTR is the direct cause of cystic

Cystic fibrosis (CF) is one of the most common fatal genetic diseases in Canada. This disease is the result of a mutation of the cystic fibrosis transmembrane conductance regulator (CFTR), located on chromosome seven. CF causes the body to produce thick and sticky mucus that clogs the lungs, causes infections, and blocks the release of enzymes from the pancreas. The first such defective gene was identified by research geneticist Dr. Lap-chee Tusi in 1989 with his team at the Hospital for Sick Children in Toronto. The mutated copy of the gene is recessive, so a child must inherit both copies of the defective allele from his or her parents in order to express CF. In the past, parents realized that they were carriers only when their child was

Cystic Fibrosis (CF or CFTR) is a life threatening disease that causes the buildup of thick and sticky mucus in many organs and body systems, and the mutated genes are passed down from parent to child. It affects about 30,000 people in the US, about 5% of the U.S Population carries the disease, but they do not have it. CF is most commonly present in Caucasians and some Hispanic. CF is less common in African Americans and Asians. Although cystic fibrosis is rare in most race, if it is inherited, it can life threatening when it isn’t treated in the early stages.

Cystic fibrosis is a autosomal recessive inherited disease that affects many organ systems. Over time the outcome for patients with the disease has improved drastically. The life expectancy for patients has increased to 37 years old, compared to 31 years old (O’ Sullivan, 2009). Researchers have reviewed the etiology, pathogenesis and clinical manifestations for cystic fibrosis.

Cystic Fibrosis (CF) is an autosomal recessive gene that causes a wide range of symptoms because there are over 1,000 changes or mutations that can occur within the cystic fibrosis transmembrane receptor (CFTR) protein. The CFTR protein is generally a chloride ion chain “regulated by cyclic adenosine monophosphate and therefore can act as a regulator of other electrolyte channels”(Grossman, S., & Grossman, L. 2005, p. 46). Typically this protein allows chloride ions to exit mucus-producing cells allowing water to flow in and thin the mucus. However, if the CFTR protein has been mutated, such as in cystic fibrosis, chloride ions cannot exit. This causes the mucus to thicken, become sticky, and obstruct the various channels it passes through. This build up of mucus also prevents bacteria from being cleaned from cells thoroughly increasing the patients risk for infections (Grossman, S., & Grossman, L. 2005). However, the severity of CF depends on whether the patients have complete or partial loss of the CFTR gene. If the person has the classic form of CF abnormalities of CFTR will commonly affect “…the respiratory, gastrointestinal, endocrine and metabolic, and genitourinary systems”(Schram, C. 2012). However, if people have atypical forms of CF their genetic disorder may only affect one of the organ systems and may not be found until the patient develops symptoms in their late childhood, early adolescence, or adulthood
