Cystic Fibrosis Research Paper

Nearly 1 in every 30 Americans are a carrier of the recessive gene that leads to CF (About Cystic Fibrosis, n.d.). Although CF is a life-threatening condition, through the advancement of treatments and care, there has been a steady increase in life expectancy and improvement in the quality of life. The current mean age of survival is now 40. Although that does not seem very high, sixty years ago, a child diagnosed with CF did not survive childhood (About Cystic Fibrosis, n.d.). CF is a complex disease, where the types and severity of symptoms can differ widely from person to person. Symptoms may include fatigue, salty-tasting skin, persistent cough with phlegm, wheezing and shortness of breath, lung infections, and poor growth and weight loss (Cystic Fibrosis Symptoms, Causes & Risk Factors, 2018). Many different factors, such as the age of diagnosis, can affect an individual's health and the course of the

In infants symptoms include coughing, wheezing, excess mucus in the lungs, shortness of breath, extremely salty skin and decelerated growth. With infants it is very common for them to develop pneumonia infections because of all the bacteria that resides in the lungs. With treatment, most patients with cystic fibrosis live into their 20’s and 30’s, some individuals with milder cases can live longer. Death is most often due to end-stage lung disease.Thus far no cure for the disease has been found. Although, research on gene therapy is promising. Treatment is generally aimed at alleviating symptoms, preventing infections, and slowing the progress of the disorder. (Egan’s 10th Ed,

Cystic Fibrosis affects 1 in every 2,500 children at birth. (ncbi.nlm.nih.gov) Cystic Fibrosis, or CF, is a genetic disorder. A genetic disorder is inherited, and is contributed to by both parents. (lung.org) Each parent has one abnormal gene. (lung.org) Cystic Fibrosis is where the body can not make, or it makes an abnormal version of the CFTR protein. CFTR is also known as cystic fibrosis transmembrane regulator. There are several symptoms, and causes of Cystic Fibrosis. These symptoms are diagnosed, according to what causes CF. Cystic Fibrosis is an inherited disease, that when after diagnosed, doctors will suggest treatments to help with the condition. Cystic Fibrosis is most common in white infants, but can

Cystic fibrosis is an inherited disorder that causes severe damage to the lungs and digestive system. This disorder is among over 70,000 people worldwide, and about 30,000 just in the United States alone. Nearly half of the Cystic Fibrosis population is age 18 or older, and are normally diagnosed by age 2. Though Cystic fibrosis is a complex disease and the types and severity of symptoms can differ widely from person to person. Many different factors, such as age of diagnosis, can affect an individual's health and the course of the disease. Today the median survival age for having this disorder is close to 40 years old. To most that might seem very young, but this is a huge improvement from what it was in past years. New advances in technology makes it possible for people with this disorder to

Cystic Fibrosis is the most common genetically inherited disease in Australia with one out of every twenty-five people are carriers of the CF gene or similar gene mutations that end in a CF , symptoms of Cystic Fibrosis depend on the level of severity of the gene. Carriers will develop thick and sticky mucus within the lungs, airways, as a result carriers will experience a persistent and difficult cough, breathlessness, the inability to exercise, constant lung infections, inflamed nasal passage is the reason the life expectancy is 25 years of age. The CF gene also has a significant effect on the digestive symptoms such as foul smelling and greasy excretes with strain to excrete, intestinal blockage, the inability to gain weight and constipation.

Do you suffer with Cystic fibrosis? If so, you may qualify for Social Security Disability Income benefits. Cystic fibrosis is an illness that can be treated, but cannot be cured. The affects of this disease can cause severe damage to the digestive track and to the lungs. Cystic fibrosis attacks the mucus membranes and digestive juices. Cystic fibrosis also causes infertility in women by blocking the fallopian tubes with mucus.

Cystic fibrosis is life threatening, progressive and genetic disorders that cause severe damage to the lungs and digestive systems. About 30,000 children’s and adults in the United States are affected by this chronic disease. Cystic fibrosis is an inherited condition which affects the body’s exocrine glands (mucus secretion glands). The secreted fluids such as mucus, sweat and digestive juices are normally thin and slippery. The secretions become thick and sticky in those people who are affected by cystic fibrosis. So the secretions plug up tubes, ducts, and passageways instead of acting as a lubricant. Therefore it is a life threatening disease since the secretions block the passageways especially in the lungs and pancreas. People with this disease are able to attend school and work but they require daily care. The treatments for this disease are getting better but there is no cure for this disease. The life spans of patients are 20s and 30s and some patients live up to their 40s and 50s. There is 25 percent chance of developing cystic fibrosis; if both the parents carry recessive gene but they do not have the disease. A 50 percent chance is there that the child will carry the gene but do not have the disease. And there is 25 percent chance that the child can be totally unaffected for the children of the couple who carry recessive gene.

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 (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

Males with Cystic fibrosis also have a tendency to be sterile. Males with CF for the most part need vas deferens, the duct which enables sperm to go to the urethra from the testicles. Oppenheimer and Esterly in, Observations on Cystic Fibrosis of the Pancreas. V. Developmental changes in the male genital system, suggest that the vas deferens does not neglect to grow yet rather it worsens in people with CF. Unfortunately, the system behind the degeneration is still inadequately caught on.

Cystic fibrosis is a genetic disorder that affects the lungs and digestive system. In order to inherit it, a child must receive a copy of the defective gene that causes it from both parents. A life-threatening condition, cystic fibrosis leads to the development of a thick mucus buildup in the lungs and other organs. This can cause recurrent infections and damage to the lungs, which can trigger respiratory failure. When the disease affects the pancreas, it interferes with the release of digestive enzymes needed to break down and absorb food. Mucus buildup in the liver can cause liver disease when the bile duct becomes blocked.

Cystic fibroses (CF) is a genetically inherited disease that is caused by a recessive allele and has to be inherited from both parents. The gene can lie dormant in both parents and they can live perfectly healthy lives however as they carry the gene it means there is a risk of it being passed onto the child. One in 25 of us carries the faulty gene that causes it (CF trust , n.d.) not many people are aware that they even carry the gene as it is only able to affect an individual if they have 2 recessive alleles of the gene. The defective gene affects the body’s ability to transfer water and salt to and from cells that produce sweat, mucus, and digestive enzymes (Alma, 2016) this means CF suffers produce a very thick sticky mucus that covers the

Cystic Fibrosis is a hereditary disease that affects the lungs and the digestive system. It causes thick, sticky mucus in the lungs that causes the lungs to clog and block the pancreas. This disease can be life threatening and the majority of people who are diagnosed are under the age of two. People with cystic fibrosis usually have a shorter than average life span. For a child to inherit the disease both parents must have the gene for the disease. Over 10 million people don’t know that they carry the gene.

Cystic Fibrosis is inherited by the parents. For a child to be affected with Cystic Fibrosis, both parents must pass the defective gene. If a child has one normal gene and one disease gene, the child does not show clinical signs of the disease, however the child is still a carrier.

This is a great improvement over survival rate of the 1950s with the life expectancy of 1 year or less for cystic fibrosis patients. Unfortunately, since it is a recessive genetic disease, there are many men and women who are carriers of the disease without actually having the disease themselves. If each parent is a non-affected carrier of cystic fibrosis, there is only a 25 percent chance of having a non-affected, non-carrier child and 50 percent chance of having a child that is a non-affected carrier of cystic fibrosis. Unfortunately there is also a 25 percent chance of having a child affected by cystic fibrosis. This makes prenatal genetic screening very important.
