Cystic Fibrosis
Cystic fibrosis is a disease that can be genetically passed down to offspring. According to the cystic fibrosis foundation’s website, “it affects the lungs and digestive system of about 30,000 children and adults in the United States,” and “70,000 worldwide” ( The online website lab tests online, records that cystic fibrosis “is a relatively common disease caused by mutations in the gene located on chromosome 7” ( This chromosome contains a protein called cystic fibrosis transmembrane regulator or CFTR and a mutation in this gene “lead to absent or defective CFTR production causing cystic fibrosis (
There are some very specific signs and symptoms of this disease. Some of the most common symptoms are: “very salty tasting skin, persistent coughing at times with phlegm, frequent lung infections, wheezing or shortness of breath, poor growth/weight ...view middle of the document...

The cystic fibrosis foundation’s earlier mentioned website also reported that “more than 10 million Americans are symptomless carriers of the defective (CFTR) gene,” “more than 70% of patients are diagnosed by age 2.. more than 45% of the patient population is age 18 or older” and about 1,000 new cases of cystic fibrosis are diagnosed each year” (
There have been many advancements in how to deal with the effects of cystic fibrosis. As a matter of fact, last week – March 4th 2010, a new inhaled antibiotic called Caysten was made available for cystic fibrosis patients ( This new antibiotic is inhaled using a breathing machine called a nebulizer and one treatment can be completed in “as little as 5 minutes” ( The cystic fibrosis foundation also indicated that with medical insurance, co pays can be about $25 ( That seems pretty reasonably affordable. There are many other existing treatments such as medications, different methods of removing mucus debris from the airways, and becoming educated on diet and nutritional items that can add to or alleviate symptoms etc. The Caysten medication just happens to be one of the newest medications.
It is a pretty scary thought that the “predicted median age of survival for a person with CF is more than 37 years” ( As I mentioned before this disease is a recessive genetic disorder so you may be carrying the gene without ever even having any signs, symptoms or even knowing that you have the gene at all. Please take the time to be genetically tested or at least find out more information by visiting the cystic fibrosis foundation’s website. Your future family may depend on it.

CF affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery but, in CF a defective gene causes the secretions to become thick and sticky. Instead of acting as a lubricant the secretions plug up tubes, ducts and passage ways especially in lungs and pancreas. CF
