Question posed by kw3647: What is the name of the test for cystic fibrosis?
Before i begin having children, I would like to be tested to see if I am a carrier for cystic fibrosis. The gene is in my husband’s family, so before getting pregnant I would like to know if I am as well

Most comprehensive answer:

Answer by JeyMacK
The most common test for cystic fibrosis is called the sweat test. It measures the amount of salt (sodium chloride) in the sweat. In this test, an area of the skin (usually the forearm) is made to sweat by using a chemical called pilocarpine and applying a mild electric current.

A question from Itri: If two people are carriers for cystic fibrosis, what is the probability that they will have a child with cy?
If two people are carriers for cystic fibrosis, what is the probability that they will have a child with cystic fibrosis?

The No 1 answer:

Answer by diendvo
This is a genetic question that requires a Punett square. Cystic fibrosis is a recessive trait, meaning you need 2 alleles for cystic fibrosis to display it phenotypically. So if you define “a” as the allele for cystic fibrosis, “A” is the normal allele. A carrier of cystic fibrosis will have the genotype: Aa. If you do a Punett square, you’ll discover that there’s a 1/4 chance the child will have the aa genotype and will have cystic fibrosis.

Question by Linda: Can I force the father of my baby to take a test to see if he is a carrier of Cystic Fibrosis?
I am 14 weeks pregnant and I have been tested and found out I am a carrier of Cystic Fibrosis. The doctors told me to have the baby’s father come in and get tested also. If the baby’s father is a carrier, it is a very high chance the baby could have CF. If the baby’s father is a carrier the doctors can start me on some things that can help prevent it from being carried to the child. However, the baby’s father is giving me a hard time about getting this done. Is there anything I can do to force him to take this test. It is just a urine test. That simple. But he is being difficult and I’m worried about my child’s health. Please help.

A question from sherry: Genetics Question please help!!?
1 in 1700 US Caucasian newborns have cystic fibrosis. “C” for normal is dominant over “c” for cystic fibrosis. What is the frequency percentage of the cystic fibrosis allele?
a. 97.6%b. 0.059%c. 2.4%d. 0.01%

Top answer:

Answer by Asst Prof
(c).

If the frequency of cystic fibrosis, cc, is 1/1700 or 0.00059, then the frequency of the c allele is sqrt (0.00059) = 0.0243 or about 2.4%

Question posed by kaliii: genetics any help is appreciated…..?
cystic fibrosis is a human disease that causes the lungs and digestive tract to fill with mucous. It is inherited in an autosomal recessive mode. A normal (non-CF) couple has already one child with CF. what are their second baby’s chance of being born with this disease?

Question posed by Karen: Hardy-Weinberg Problem??PLZ HELP 10pts!!!5Stars.?
After graduation, you and 19 friends build a raft, sail to a deserted island, and start a new population, totally isolated from the world. Two of your friends carry (that is, are heterozygous for) the recessive cf allele, which in homozygotes causes cystic fibrosis.

A. assuming that the frequency of this allele does not change as the population grows, what will be the instance of cystic fibrosis on your island?

B. Cystic fibrous on the island is how many times greater than the original mainland. The frequency of births on the mainland is .059%.

please help me with this and explain in full steps because these are just practice problems for our test at the end of this month. Thanks to everyone who answers. best explainer will get 10 pts and 5 stars! =)

Best answer:

Answer by Arnab
it should be 1/20 because out of ten couples only one couple(the 2 people carrying the recessive trait) have 25% chance of having offspring with disease and 50% chance of having heterozygous children, whose 50% of gene is diseased

A question asked by jedi knight: Does anyone have cystic fibrosis please help me?
ok so ive been going to the doctor for about 2 year and they just told me they thing they know whats wrong with me they think i have cystic fibrosis because they did the sweat test and it was high but there gonna redo the test and do more test to make sure i have it.. do you i have it? they said if i have its a mild case. how long do people with mild case have to live ? tell me about your life if you have cf and how it is with doctor and treatment and stuff tell me about it thank i would appreciated it

Selected answer:

Answer by Kelly H
If the sweat test came back positive then it is likely that you do have CF. Another sweat test and a DNA test will verify the diagnosis.

My seven year old daughter has Cystic Fibrosis. There are over 1,000 different Cystic Fibrosis mutations and even people with the same genetic defect have different symptoms. My daughter’s genetic defect affects both her lungs and her digestion and we knew as soon as she was born that something was wrong. If you are old enough to post this question and you are only now getting sweat tested then I am guessing that your symptoms are on the milder side and that is why your doctor is telling you that if you have Cystic Fibrosis that it is a milder case. There are people in their sixties that have Cystic Fibrosis. I believe these are the people who fall into the milder case category.

Three pieces of advice if you indeed have CF:
1. Limit your research about CF on the Internet. www.cff.org is the CF website and it is very informative. I say this because the personal situations that are posted are often not the norm and it is highly unlikely that they will apply to your case. And as I said, each person with CFs situation is different. Feel free to contact me at any time if I can be of any help.
2. Find a good CF clinic and a CF doctor that you like and feel comfortable talking to. We went through several doctors before we found the right one for us.
3. Make your health a priority. If you are prescribed breathing treatments, medications, etc. Make sure that you do them. They are not an option. Use a lot of hand sanitizer and have the people around you use it too.

My daughter’s life is not a good representation of someone with a milder case but it will give you an idea of what it is like to live with CF. Important…my daughter’s CF situation would not be considered mild so her treatments and therapies may not apply to someone with a milder case of CF. She has to take enzymes with anything that she eats to help her digest her food. She has to eat double the calories of someone her age to maintain or gain weight. She does breathing treatments twice a day and uses a vibrating vest to help loosen mucus in her lungs. She does the breathing treatments and the vest more often when she is sick. She also has some other medications that she takes. She goes to the CF clinic every eight weeks to have her lungs and weight checked. Overall I would say that her life is not easy. But CF is a part of who she is. She is a lot of fun, she loves life and she finds joy in everything. All of the people that I have met with CF are like that.
There are two drugs that are in phased trial testing that show extreme promise for helping to correct the CF defect within a person’s cells. So, there is realistic hope that a cure will be found.

Answer by Mikhail0603
You don’t tell your age. The “Gold” and definitive test is genetic testing. Your insurance will cover that. Blood is taken from your vein and sent to a clinical facility like Genzyme in Cambridge, Massachusetts. There are “mild” cases of C.F. I have a “mild” case. I’m 63 years old and had no symptoms until age 54! I’m doing fine. I’ve had a few infections where I did a lot of coughing and brought up green sputum. It was cultured at the hospital lab and I was given the appropriate medicine and the infection cleared up. Have your liver and pancreas checked for Steatosis. If you have it, especially in the liver, stop drinking alcohol.

Question posed by Paige Morgan: Question about Cystic Fibrosis?
My friend has Cystic fibrosis, but I think it’s not so severe.
He was born in 1995, and I think there were lots of problems when he was young and he had some surgeries. He lives in Israel. He goes to the hospital every month for some kind of test and last year he started a kind of experiment (?) where they put something tight on his neck area for about a day, take pictures and stuff. If it’s the right treatment it will help him.
I know he takes lots of medicine and Enzymes before he eats. He’s the right size for his age.. and he runs a lot, he’s in a very good shape. His record is I think about 13.5 KM, and he ran 10K in 49 minutes. (Just to show you that he runs a lot and is very fit)
What can you tell me to make me understand more? And what would you say his life expectancy would be?

Well they say 16 to 18 but my sisters best friend is 40 and had it very bad. Het SIS died at 16 from it. It’s a genetic disorder that effects the respitory system. They thought my son had it but he has bad asthma. U can Google info on it. We would have to beat that girl in the back every morning just to get the junk out. of her chest. Good luck.
