Question posed by allyson2626: Cystic Fibrosis Testing and the R117H Gene?
My doctor just called and I have test positive as a cystic fibrosis carrier. We are still waiting on the results of my husband’s test. On top of this I have a mutation in my gene called a R117H. He said it may cause sterilization if this is a boy. I am having trouble finding any information written in lay men’s terms. Does anyone know any additional information? Has anyone had this? What is the likelihood that this will cause sterilization if it is a boy?
Thanks so much. I am trying not to worry, but I would like to be informed before they send me to a specialist…

Check out the website below that is where this statement comes from.
Cystic fibrosis is a genetic disease that is associated with abnormal sweat electrolytes, sino-pulmonary disease, exocrine pancreatic insufficiency, and male infertility.
Here is another site you might find out some more information.
Hope these two site will be help to you. Good luck

A question asked by teshiunata: In humans, cystic fibrosis is caused by a recessive gene that is not sex-linked. ……?
In humans, cystic fibrosis is caused by a recessive gene that is not sex-linked. A man and a woman, neither of whom has cystic fibrosis, have two children with the disease. What is the probability that their third child will have the disease?

CF is a recessive gene, the baby needs to get a copy of the gene from both mum and dad before it gets it. The previous children have no impact on future pregnancies.

Question by Sekkennight: I want to become an egg donor, but I am a carrier of the Cystic Fibrosis gene will that make it so I can’t?
I want to become an egg donor, but I am a carrier of the Cystic Fibrosis gene will that make it so I can’t be an egg donor? No one in my family has ever had it, so I was just wondering if just being a carrier of the gene would make it so I could not.
If you answer this please KNOW the answer, don’t just guess.

YES!!!!!!!!!!!!! ANY THING LIKE THAT THAT IS GENETIC IS A CAUSE FOR CONCERN THEY WILL PROBABLY SAY NO DUE TO THE HIGH RISK.

A question from Pree Kay: What is the mechanism whereby the faulty Cystic Fibrosis gene causes production of thick mucus?
I have to draw a flow chart illustrating this. I looked on google for a long time but could not find much information. (It’s for Biology 12)
Most detailed answer:
Answer by Edric Z
As I understand it, it is primarily caused by an over absorption of liquid in the lungs into the lungs tissues. Not sure if the high sodium / low chloride content contributes to the viscosity or not. Pulmonary therapies add moisture and medications into the lungs to help liquefy the mucus so it can be expelled. This helps clean the lungs of foreign material as well as the buildup of mucus. Vigorous shaking/vibrating or percussion’s to the lungs also help the mucus to liquefy for expulsion.

A question from Microbiology2011: If two parents, are heterozygous carriers of the autosomal recessive gene causing cystic fibrosis,?
If two parents, are heterozygous carriers of the autosomal recessive gene causing cystic fibrosis,
have 5 children, what is the probability that: (8pts)
a. three will be normal?
b. four will have cystic fibrosis?
c. all are normal?
The best answer:
Answer by Julie
You’ve got a 50% chance of a carrier, 25% chance of one effected, and 25% of a normal offspring.
Chance of three being normal= .25x.25x.25… so 1.5625%
Chance of four having CF= .25x.25x.25x.25= .039%
chance of five being normal=.25x.25x.25x.25x.25= .097%
