One gene bad: The cftr gene codes for (has information for your body about) a sodium-chloride transporter on your cell membranes. If you have two bad copies you have cf, if you have one, you are a carrier. As many as 1 in 25 caucasian adults in the us has this mutation. If you are planning on having children, talk to your spouse about genetic counseling, unless your spouse is of Asian or african descent.
