Cystic Fibrosis Cystic Fibrosis is one of the most widespread genetic disorders in the modern world. While only 30,000 members of the American population is affected by the disease, millions of Americans are carriers of the disease; the difference between carriers and sufferers of the disease lies in the autosomal recessive nature of Cystic fibrosis. A truly documented history of Cystic fibrosis did not exist until well into the 1930s, although people did have an idea of what it was, as shown by the old German saying that “A child whose forehead tastes like salt when kissed will soon die”. It was not until recently that scientists learned that the disease arises from a mutation in the CF gene located on chromosome 7. This is the gene that is responsible for the proper production of the protein CFTR, a protein that controls the movement of salt and water in and out of the cells in a person’s body. In a person with Cystic fibrosis, the lack of a properly functioning CFTR protein causes for the production of sticky mucus that is excessively thick and very salty sweat. This mucus can then either clog the airways, causing progressive damage and complications with the respiratory system, or can also block ducts in the pancreas, which basically causes vitamin deficiency and malnutrition. Cystic Fibrosis currently has no cure, but there are many treatment options to help minimize the effects of the disease to help people live well into their 40’s or 50’s. Nowadays there are a lot of organizations and charities aiming to raise awareness of the disease to provide researchers with enough money to hopefully find a cure, and with new aspects of the disease being learned with each project, the hope of a cure does not seem that far-fetched.

    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 are chloride and sodium. The CFTR protein, which is created by the CFTR gene, has a molecular weight of 168,173 daltons and in length, is 1480 amino acids long. This variation in genes is located in chromosome 7 of humans. Because most people have two of the CFTR gene which creates the CFTR proteins, a person can be completely healthy with a mutation in the gene, as long as at least one of these genes are unchanged from the normal state. 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 protein can be modified in numerous ways to give the host cystic fibrosis; in fact, over 1000 transformations of the CFTR gene have been recognized. One of the most common of these mutations is a deletion of a single amino acid from the long chain of 1480 in the CFTR protein. This causes a breakdown of the channel made with the missing amino acid, which means that it never transports chloride ions, like it was made to do, because it never reaches the cell membrane. This mutation is delta F508, because the deletion occurs at position 508 on the CFTR protein. These sorts of mutations work to deteriorate and destroy the efficiency of the CFTR protein by changing or replacing parts of the protein’s amino acid order. This order chooses the way that the protein is folded, and if this order is…

    Starting thirty years ago, Australians are tested at birth for a range of medical conditions including the spoken genetic disorder, but doesn’t always detected everyone immediately. 15% percent of people carrying the disease can be identified when in adulthood. If the person is effected by the mutation, symptoms such as bowel blockages after birth can make a diagnosis for babies, but the absolute test is the ‘sweat test’. This is where sweat samples are taken and if chloride levels are above sixty percent the person is detected to be effected by the mutation. Also babies effected don’t gain weight and thrive normally regardless of a nutritious and proportioned diet. During pregnancy, a mother can test for Cystic Fibrosis but can’t currently predict if the child is effected or a carrier, or predict the severity of the symptoms. An autosomal recessive disorder states that a mutation must be present in both parents in order for the disease to develop. Cystic Fibrosis is an autosomal recessive disorder, and thus occurs equally in both male and…

    Cystic fibrosis is a genetic disease, and it is inherited by autosomal recessive, which means that there must be two copies of an abnormal gene and it has to be present in order for the disease or trait to develop. While I was learning about autosomal recessive, I learned that gene’s come in pairs and both pairs must be defective to cause a disease. As I looked deeper into Cystic fibrosis I learned that it affects the respiratory system and also the digestive system. This disease is a defect in the chromosome 7, chromosome 7 is also known as CFTR or cystic fibrosis transmembrane conductance regulator. Like most diseases these days the way it affects someone or shows in someone depends on the severity of the disease. For instance, the way cystic fibrosis shows in a child may be completely different compared to someone in there later ages. For the most part the symptoms are always the same for both the respiratory and the digestive system. When it comes to the respiratory system the symptoms that you need to look for is a constant cough that produces a lot of mucus, Wheezing or feeling breathlessness. Always having a stuffy nose and not being able to exercise the way you may want too is also a symptoms due to the respiratory system. As you can tell from the…

    CF is an autosomal recessive disorder caused by a mutation of the gene that encodes for a chloride channel called the cystic fibrosis transmembrane conductance regulator (CFTR). In ductal epithelial cells, CFTR is highly expressed and functions to transport fluid and anions into the lumen. Dysfunction of the CFTR gene leads to a decrease in luminal fluid volume and decreased pH, resulting in protein precipitation within the ductal lumen and loss of normal acinar cell function. Estimated gene frequency of cystic fibrosis varies in different ethnic groups with highest incidence in Caucasians (1 in 2,500). Approximate incidence of CF in South Asians immigrants settled in UK is about 1:10,000 to 1:12,000. CF is one of the under diagnosed diseases…

    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 two copies of the faulty allele (are homozygous), they will have CF. People who have CF must consider that their children will definitely be carriers at the very least, and depending on the genotype of their partner, may also suffer from CF.…

    abies born with CF don't gain weight as expected. They fail to thrive in spite of a normal diet and a good appetite. Mucus blocks the passageways of the pancreas and prevents pancreatic digestive juices from entering the intestines. Without these digestive juices, the intestines can't absorb fats and proteins completely, so nutrients pass out of the body unused rather than helping the body grow. Poor fat absorption makes the stools appear oily and bulky and increases the child's risk for deficiencies of the fat-soluble vitamins (vitamins A, D, E, and K). Unabsorbed fats may also cause excessive intestinal gas, an abnormally swollen belly, and abdominal pain or discomfort.…

    Cystic Fibrosis is a genetic disorder that block some areas of the body with a mass of mucus. This disease is very common and affects one out of four people. It can only show when the offspring inherits two copies of the defective Cystic Fibrosis gene. The gene controls movement of water and salt, which causes the mucus. Although this disease does not sound threatening, the levels of dangers vary. There are treatments for this disease and this insures to some that they can live almost normally.…

    While Cystic Fibrosis effects multiple organs and systems of the body, the organs most effected are the lungs, making it a predominantly respiratory disease. It manifests itself mostly in chronic, recurring lung infections but presents initially with signs and symptoms not necessarily respiratory related. One of the earliest signs of CF is failure to thrive. Sure, maybe your child is the runt of the litter (like myself) but if they’re eating you into the poorhouse and not growing or gaining weight at all, that is failure to thrive. Houston, we have a problem. Basically what’s happening is the infant is not absorbing fats properly, which translates in to malnutrition and bowel movements that…
