Cystic_Fibrosis

Cystic Fibrosis Statistics Cystic Fibrosis (CF) is among one of the most prevalent genetically innate disorders in the United States. CF is generally diagnosed in infancy and ‘roughly five percent of white Americans are symptomatic carriers, harboring a single mutant gene in their cells’ (Ryley, 2001). According to the data given by the Cystic Fibrosis Foundation, the average survival age of a person living today with cystic fibrosis is 31.3 years which is atypical when weighed against 50 years ago when a infant diagnosed with cystic fibrosis was not expected live outside of childhood. Cystic Fibrosis carriers are born with a recessive gene that can be altered in up to twenty ways. Although only one mutated gene needs to exist in order to be deemed a carrier, in order for the child to exhibit symptoms of CF, two autosomal recessive genes must be present. Statistically speaking, if two carriers if two carriers of cystic fibrosis married, there will statistically be one of three outcomes: 1. Fifty percent chance the child will be a carrier. 2. Twenty-five percent chance that the child will have cystic fibrosis. 3.
