ChoiH+Cystic+Fibrosis

Cystic Fibrosis Cystic Fibrosis is a genetic disorder that affects the respiratory and digestive systems. When proteins produced by the gene, chromosome 7 does not function correctly, that procedure is blocked and an unnaturally thick mucous is produced outside of the cell. Mucous start to block out the airways in the lungs, and higher the chances of risk of infection by bacteria. Mucous also affects the pancreas and sweat glands.

 * Inheritance: **

Since Cystic fibrosis is a recessive disorder, both parents must pass on the defective trait and anyone of their off-springs may inherit this genetic disorder.

People who have cystic fibrosis have the symptoms of: coughing or wheezing, respiratory illness, weight loss, salty tasting skin, and greasy stools.

 * Diagnosis: **

In newborns, doctors can measure the amount of a protein called trypsinogen in the blood. Doctors can use a sweat test to measure the amount of salt in a person’s sweat. Finally, genetic tests can identify CFTR (Cystic Fibrosis Transport Regulator) gene using a sample of the patient’s blood.

Cystic fibrosis is treated by chest physical therapy, in which the diseased is hit on the back numerous times to allow the mucous in the chest to free. Inhale antibiotics, to destroy the bacteria that cause lung infections, pancreatic enzyme replacement therapy, to allow food to properly digest. Finally gene therapy in which the healthy CFTR gene is inserted into the lung cells of a patient to redress the defective gene.

Researchers are working hard to find a cure for cystic fibrosis. These researches have lead up to new drugs and treatments that have dramatically improved both the life expectancy and quality of life, and soon doors will open up for researchers to find a cure.
 * Research: **

Cystic fibrosis requires lifelong care. Cystic fibrosis is not preventable to the unborn. <span style="color: black; font-family: Times,serif; font-size: 12pt;">More than 1,000 different mutations in the CFTR gene have been identified in cystic fibrosis patients.
