What causes Cystic Fibrosis

CF is a genetic condition. Though it is most common among Caucasians (It is estimated that in the UK 1 person in 25 carries the faulty CF gene, usually without knowing), children of other races have been diagnosed with the condition as well. If two carriers have a baby, the child has a 1 in 4 chance of having Cystic Fibrosis. CF is not contagious as it can only be caused by inheriting two copies of the faulty gene.
