Cystic Fibrosis Continued
	If the test for both spouses comes back positive for being carriers of the defective gene, there is a way that children are still a possibility without having to worry about becoming pregnatn with a Cystic Fibrosis Child.  Scientists are now able to take a sperm cell from the father, and an egg cell from the mother, remove the defective gene(s)from both, and then fertilize the now CFTR free cells.  A major downside of this procedure is it's cost, which can run from $10,000 to $25,000 for each attempt. ESSENTIAL QUESTION: What causes the mutation in CFTR and how does it affect the organs of the body? As a consensus, scientists are saying that they do not know what caused the mutation in CFTR in the first place.  Scientists feel that CFTR is developing and mutating so quickly, and with so many different variations, that it's origin may never be discovered.  In that way, it is much like the AIDS virus.  Every time scientists introduce CFTR to a new antibiotic or treatment, it mutates, or changes, its chemical makeup so that it becomes resistant.  The wide scale of mutations makes it hard for science to keep up.
