Genetic testing

On Thursday, I got the results back from the testing we had done at my 16-week appointment.
The AFP test, which is used for detecting things like neural tube defects, abdominal wall defects, esophageal and duodenal atresia, some renal and urinary tract anomalies, turner syndrome, some low birth weight fetuses, placental complications or Down Syndrome, came back low risk. It was fantastic to hear that news.
But on the cystic fibrosis test, we weren't so lucky. My nurse, Monica, told me that I'm a carrier. One of the 32 genes they tested had a mild mutation, she said. One in 29 people are carriers.
The next step is to test Dan to see if he's a carrier. After talking about it, we decided that's something we wanted to do. He went in for the blood work on Thursday. We should find out the results sometime between Tuesday and Thursday of next week.
If Dan is a carrier of cystic fibrosis (and as I understand it, it would have to be a mutation of the same gene as I have) then our child has a one in four chance of having cystic fibrosis. If it's determined that he's not a carrier, then we have nothing to worry about.
While the chances are slim, it's still scary.
