cf gene

[Guest guest]

hi everyone,

i have been told by my doctors that they can not find the gene for

cf in a blood test even though i have tested positive for the sweat

test four times and have been diagnosed with cf. they said that they

can't test my mother or father for the genes because they would be

identical to mine and if mine don't show up neither would theirs.

they also can't test my sister for the same reason. i am thinking of

adopting because of the cf and how the pregnancy would affect me,

but my sister how dose not have cf could still pass it on to a child

if she were to have one from what i understand. is there anyway to

find out about the gene so that we could give her a heads up. she is

only 19 and a long way from having children but i wonder just the

same thanks mindy.
