Cystic fibrosis and pregnancy?

i am 24 weeks pregnant and just found out i am a carrier for cystic fibrosis. i should have been notified this 2 months ago when i took the test, but i wasnt! now the midwive tells me ( you have the rarest form) a form she has never seen before?? my husband is african american so im told this is a good thing as he has a low chance of caring the gene,, but im wondering what form i am carrying and why she looked so confused on the type???? does anyone know the differnet forms or the rarest form of cystic fibrosis?? yes im gonna call them tommarrow belive that to have it out with them why i had toask for my positive results and what form this is exactly, but they are closed now.. so im anxious and curious??? please anyone that knows can i have some advice???

Sorry that this has caused you worry. For you to have a child with cystic fibrosis, you need to be a carrier, and your husband needs to be a carrier, then you have a 25% chance of having a child with cystic fibrosis. The hospital will probably recommend that your husband be tested to see if he carries the gene as well. What ever the results are, you should see a genetic specialist to explain the tests and results and potential implications.

All babies (in Australia, and in most other Countries) are tested when they are 72 hours old via a heal prick blood test or NBST New Born Screening Test. This test will often show up as a 'positive' for cystic fibrosis, which just means that the baby will need further testing, most often it is that they are a carrier of the cystic fibrosis gene, not that they actually have it. There are many different disorders that the NBST covers.

So try not to be so anxious, the chances of having anything wrong with your baby are very remote. So sit down, relax, and get your husband to give you a foot massage. :)

I saw you weren't getting answers so I'm jumping in. I don't know much about it but there are over 500 types so yours might not be literally the rarest. The site below has an explanation of the more common types. The one you have the gene for may be related.
