My pediatrician just called and informed me that Blakes PKU came back positive for cystic fibrosis, UGH...
I thought both parents had to be a carrier. I know my SIL is a carrier so my DH could be too. I was negative. Does this mean he HAS it or could be a carrier? ANy advice would be appreciated :(
I think only one parent has to be a carrier, but I'm not sure on that. I was just reading an article on that a couple of months ago. Now I wish I had paid closer attention to it. I also know that some women who are carriers won't always show positive when in fact they are.
Gee Kellie, I'm so sorry you have to go through all this worry. Is your dh home, or out of town?
Yes, both parents have to be a carrier in order for the baby to have a chance at actually having cystic fibrosis. So your doc must mean that Blake is a carrier. If you know for a fact you're not a carrier, then Blake can't have it.
She didn't say anything about a sweat test. I just went to Quest and had his blood drawn. And it sux to think I thought the Dr. was so sweet to be calling just to check up on 3 week ole Blake... The Dr. said if it is indeed CF she will refer us to a specialist (don't remember which kind) I think a lung or heart? From what I've read, probably lung. Poor DH is a pilot and out of town. He is crushed, especially because he has to be the carrier because I'm not. Don't worry, he flies cargo :) My Dr. said 1-2 weeks for the results, Quest said maybe Monday? So,.....I'll just wait, and read.....
My heart sank when I read your post. I had to do some research and hopefully it will help. Everything I can find says that to actually have the disease, you have to have received a defective gene from both parents. If you are not a carrier than it seems that your son would just be a carrier but not actually suffer any symptoms. I hope that this is the case. I copied some info I found and hope that you get some definate answers soon.
I'll be praying for little Blake. Try not to let yourself get too freaked out until you have definate answers. I know that is easier said than done.
There are several ways to help answer these important questions.
Genetic Carrier Testing — More than 10 million Americans are symptomless carriers of the defective CF gene. This test can help detect carriers, who could pass CF onto their children. To have cystic fibrosis, a child must inherit one copy of the defective CF gene from each parent.
Each time two carriers of the CF gene have a child, the chances are:
25% the child will have CF;
50% the child will carry the CF gene but not have CF; and
25% the child will not carry the gene and not have CF.

Newborn Screening — Newborns screened for cystic fibrosis can benefit from early diagnosis and treatment, which can:
Improve lung function;
Reduce hospital stays; and
Add years to life.
While newborn screening is not a definitive diagnostic test for cystic fibrosis, it may lead to tests that can rule out or confirm a CF diagnosis. The Cystic Fibrosis Foundation and the Centers for Disease Control and Prevention recommend screening for cystic fibrosis for all newborns.
A defective gene causes cystic fibrosis. The gene controls the production of a protein that controls how salt is carried across the membranes that separate cells. People with one copy of the defective gene carry it but have no symptoms, which is the case for more than 10 million Americans. However, those who receive a copy of the defective gene from both parents will develop cystic fibrosis.
Girls, I just can't get worked up about it because all I read says that the mom and dad have to be at least a carrier and I'm NOT, I even checked again w/my OB.........
Well, I'm no Dr. but thanks for all your well wishes and I WILL keep you posted :(
I am a CF carrier. I found out when I became pregnant. I had a week of the jitters while they tested DH. He is not, so the dr was not concerned at all. The previous posters and what you have read are right- both parents have to be carriers.
I am confused though, as to why he would refer you to a specialist if he were just a carrier.
OMG Kelly...will be saying lots of prayers. It sounds like from the posts all will be fine, but I'm really sorry you have to go thru this stress. When my 7yr old was born he ended up being VERY delayed (80-90% behind at one year) and we were told while the neurologist ran tests that we best be prepared for a fatal illness. I locked myself in a dark closet and cried and cried and cried. It was hell waiting 8 darned weeks for some of those tests to come back, but I learned my life saying, "It is what it is" because I realized he was the same child I was hugging then as he was the day before and I couldn't control the outcome of the tests so I absolutely could not worry. Anyways, he's fine...well the spaz has ADHD and drives me nuts (:0)) but I love him to pieces...he's alive and didn't have any fatal illnesses. Gosh darned doctor for telling me he might. And of course I googled everything I could find. STUPID. You have a great attitude w/ this and I just know it will all be okay. But I've been there and know you will be worrying anyways despite it all. I'll be thinking and saying prayers for you.
