In ,b The foundation created the Research Development Program, which is a network of research centers at top universities. In the lungs, the production of the thick mucus also increases the likelihood of infection, so people with cystic fibrosis are known to have lungs with copious amounts of bacteria in them.
It only occurs in children who have inherited two abnormal copies of a specific gene, one from each parent. When cystic fibrosis was first Cystic fibrosis essays, there were no treatments available.
Lung disease is the cause of death for most CF patients.
Parents can notice this symptom when they kiss the affected infant because their skin will be salty-tasting. However, treatments are available to increase the average life span. One of the most common symptoms Cystic fibrosis essays CF is loss of excessive amounts of salt.
Treatment has developed to the point that the average age to which cystic fibrosis patients survive has been raised to forty-one years of age. Simple exercise is always good for patients with cystic fibrosis, because it will help to sweat out the excess salt that cannot get out of the body because of unusable protein channels.
The water in the cells stay there to dilute the chloride instead being drawn out by normal chloride movement and the normal secretion of the organs thicken. Other common symptoms are persistent coughing and wheezing, clubbing of fingers and toes, easy.
The disease is most common in whites whose ancestors came from Europe, causing about two to five percent of Caucasians to carry the cystic fibrosis gene. CF affects different patients in different ways. Cystic fibrosis was discovered in the s by the Bohemian pathologist Carl von Rokitansky, who made the first description of the disease as part of a report about a death of a fetus.
In a group of parents founded the Cystic Fibrosis Foundation, which later became the National CF research Foundation in as well.
One in every seventeen-thousand African Americans is a carrier of the mutated gene, and one in thirty-thousand Asian-Americans is a carrier. To solve problems of lack of nutrition or vitamins, injections can be arranged, of the nutrients themselves, or of enzymes that the pancreas naturally makes.
CF carriers can pass on their normal copy of their gene or they can pass on their abnormal copy. Although a child that receives an abnormal gene from both parents will develop CF.
CF affects the respiratory, digestive, and reproductive system. With the knowledge of this gene, scientists could also, for the first time, synthesize a healthy version of the gene for research. Overall, the Caucasian race is most susceptible to having cystic fibrosis.
One of the most common of these mutations is a deletion of a single amino acid from the long chain of in the CFTR protein. CF affects the reproductive system in females because they produce a thick cervical secretion that may block sperm entry and prevent them from getting pregnant.
However, many different medications and activities help to lower chances of harmful symptoms of cystic fibrosis and help to prevent certain fatal events from occurring. This is caused by the other symptom of not being able to digest foods and retain nutrients. Because cystic fibrosis is a hereditary disease, different populations are more or less likely to have this mutation in the CFTR gene.
In fact, this symptom of not being able to absorb nutrients or digest foods causes many other symptoms. The mutation in the CFTR gene causes a disruption of the chloride transfer across the cell membranes. Inwhen the CFTR gene was discovered, scientists were intrigued, and ingene therapy for cystic fibrosis patients began.
About 2, babies are born each year with CF in the United States. InDorothy Andersen M. When folded improperly, the substances for which the protein was made cannot fit through the protein channel, and so cannot pass through it. The phenotype or physical appearance of anyone with the autoimmune disease cystic fibrosis varies, as there are multiple possibilities and combinations, but have many recurring traits.
Also, a thick secretion may block the ducts that carry the sperm, or the ducts may not develop normally. Most of the hope in curing or treating cystic fibrosis has been placed on drugs and gene therapy. In this case, the protein is a protein channel inside a membrane, and if folded improperly, the molecules that would normally pass through it are not able to, which means that the structure has failed to do its task, which is the transport of chloride and sodium across epithelium tissues.
On average, the life span of a female with CF is 25 years and 30 years for a male with CF. Chloride ions build up in the cells of the lungs and other organs. Because cystic fibrosis helps to prevent the movement of salt and water in and out of cells, the lungs and pancreas begin to secrete thick mucus, which will eventually block passages within the body, eventually rendering the passageway useless from clogging.
One in every twenty Americans is an unaffected carrier of an abnormal CF gene, and these twelve million people usually do not know that they are a CF carrier. Pills have also been developed to thin mucus in order to prevent the extraneous buildup of mucus in the body. This failure is caused by the altered fold of the protein, because proteins function only when the proteins are folded perfectly.Cystic Fibrosis essays I have always been interested in the health field, espicially certain diseases.
One disease that really interests me is Cystic Fibrosis, this is because I know someone who has it. I have always wondered what it is, the different symptoms, how it is tested for, treatments, and. Read Cystic Fibrosis free essay and over 88, other research documents.
Cystic Fibrosis. Cystic fibrosis, also known as CF, is an inherited disease that affects the body’s mucus glands.
CF is the most /5(1). 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. Cystic fibrosis is an inherited disorder that affects the way salt and water move into and out of the body's cells. The most dangerous effect of this disease is the fact that thick mucus blocks the tubes and ducts of the lungs and the digestive system.
The problem with the lungs can lead to. Without the cystic fibrosis variation of the CFTR gene, the CFTR proteins created by the gene act as a channel protein which can be found in the membranes of cells which line the passageways of organs such as the pancreas, lungs, and intestines.
The CFTR. Learn about cystic fibrosis, a genetic disorder that affects the lungs, pancreas, and other organs, and how to treat and live with this chronic disease.Download
