Cystic Fibrosis Poster!

Symptoms CF is a multi system disorder, so there are a variety of symptoms…*A destruction of lungs and loss of lung function eventually causes death.-Salty-tasting skin-Frequent coughing -Difficulty breathing that worsens over time-Foul-smelling, greasy stools-Poor weight gain and growth-Intestinal blockage, particularly in newborns (meconium ileus)-Severe constipation-Breathlessness- Exercise intolerance-Repeated lung infections-Inflamed nasal passages or a stuffy nose-WheezingOver time, the symptoms of cystic fibrosis can worsen and become…Diabetes, gallstone, liver Disease, and pancreatitis (painful inflammation of the pancreas)

Inheritance Pattern Cystic fibrosis inherits a defective gene called CFTR (cystic fibrosis trans-membrane conductance regulator).Cystic fibrosis is a recessive disorder, which means that both parents must pass on the defective gene to any of their children for them to get the disease. If a child inherits only one copy of the faulty gene, he or she will be a carrier. Carriers don't actually have the disease or the symptoms, but they can pass it on to their children. But when a child inherits 2 abnormal genes, one from each parent they have the genetic disease.

Cystic Fibrosis

-Medication, inhaled drugs:Medication such as antibiotics, ibuprofen, and salt solution can thin the large amounts of mucus, clear the lungs, and fight infections. These drugs also fight inflammation and reduce swelling in the lungs-Supplements:Since cystic fibrosis affects the intestines, by taking supplements your body can absorb more nutrients that the intestines aren’t able to absorb.-Oxygen therapy:When someone has a severe lung disease, such as cystic fibrosis, they might have to breathe through a mask or prongs in the nose in order to obtain a sufficient amount of oxygen.-Exercise:Aerobic exercises that increase the rate of your breathing can help loosen the mucus and cause you to cough it up.

Treatment There has been an increasing amount of research done, that is leading to the outstanding progress to find a cure to cystic fibrosis. Some research has discovered the responsible gene for cystic fibrosis, this allows them to target the cause of the disease and not it’s symptoms. At the moment there is no cure available for patients who have cystic fibrosis. However, there are many treatments available to support those who have it and to help relieve them from the symptoms.-Airway techniques and exercises (Chest Physical Therapy). Chest physical therapy involves pounding your chest and back repeatedly with your hands to loosen the mucus in your lungs in order to cough it up. You may also use special devices to help during this process (mechanical precursor, inflatable therapy vest etc.)

Punnet Square The probability of two heterozygous parents concieving a child with CF is 25% and a child who is a carrier is 50% and a child who is does not the mutation is 25% aswell.

What is it?Cystic fibrosis (CF) is a hereditary disorder and is the most common fatal genetic disease in Canada. Chromosome 7, is the one that is responsible for the production of a protein called cystic fibrosis trans membrane regulator (CFTR). It causes the production of abnormally thick mucus, leading to the blockage of the pancreatic ducts, intestines, and bronchi and often resulting in respiratory infection. The life expectancy for people with cystic fibrosis is less than 40 years of age. This producution of thick sticky mucus clogs the airways in the lungs, and increases the risk of infection by bacteria, therefore the lung cells get effected. It is a result of a mutation or a change in the genetic code, the first defective gene was identified through research in 1989 at Sick Kids hospital in Toronto. It is a recessive gene, so a child must inherit both copies of the defective allele from his or her parents.

The mutation of Cystic Fibrosis is too small to actually see on a karyotype, but it effects the 7th chromosome.
