Question by Quin: what are the treatments of cystic fibrosis?

The best answer:

Answer by Ride4Life
Here is a list of ones that I use. enzymes, oral antibiotics, inhaled (nebulized) antibiotics, pulmozyme, allergy medication, asthma inhalers (Xopenex and Advair), I have to use insulin for CF related diabetes,IV antibiotics with flare ups, physical therapy (the Vest and actual physical activity), multiple vitamins like Aqua ADEK, 16,000 units of Vitamin D, 300 mg of CoEnzyme Q10, I am forgetting a few but that is what is prescribed for me, some other people with CF may be similar or totally different. Everyone has different needs.

A question from The Waffle: Another genetics problem?
Imagine that you are a genetic counselor, and a couple planning to start a family come to you for information. Charles was married once before, and he and his first wife had a child with cystic fibrosis. The brother of his current wife Elaine died of cystic fibrosis. What is the probability that Charles and Elain will have a baby with cystic fibrosis? (Neither Charles nor Elaine has cf).

Please explain and not just do the problem

Best answer:

Answer by Mr. Biostud
Considering the fact that cystic fibrosis is an autosomal recessive trait we can represent the affected individual’s genotype as aa. The normal is AA and the carrier is Aa. If this is the case then we can calculate the probability of the couple having a child of their with CF.

Since Charlie do have a child with CF and he himself doesn’t have it we can conclude that he is a carrier (genotype Aa). Moreover we can also confidently suggest that Elaine herself is a carrier base on the premise that his brother died of it and she is not affected. Once again her genotype is Aa.

The probability therefore for this couple to have a child with CF is:

Aa x Aa=1/4AA (normal),1/2Aa (carrier),1/4aa (affected)

The probability therefore is 1/4.

Hope this helps…

Question posed by ham and cheese: autosomal recessive disorder genetics problem?
Cystic fibrosis is an autosomal recessive disorder. A male whose brother has the disease has children with a female whose sister has the disease. It is not known if either the male or the female is a carrier. If the male and female have one child, what is the probability that the child will have cystic fibrosis. My book says the answer is 1/9, how could that be possible? I keep getting 1/16

The best answer:

Answer by Lori G
Each parent has a 2/3 chance of being a carrier (1/3 chance of being normal, 2/3 chance of carrier, and they obviously don’t have cf). Then there is a 1/4 chance of an affected child if they are both carriers… so 1/4 x 2/3 x 2/3 = 4/36 = 1/9.

hope this helps!

It a genetic disorder which is inherited. You can easily get tested to see if you or your spouse carry the gene.

Best answer:

Answer by gangadharan nair
Cystic Fibrosis: This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Question posed by misty: Can someone help me with genotype frequency?
A rare recessive allele inherited in a mendelian manner causes cystic fibrosis. A phenotypically normal man whose father had CF marries an unrelated woman and they consider having a child. If the frequency of heterozygotes for CF in the population is 1 in 50, what is the chance that the couples first child will have CF? Give reasons for your decision.

Thanks for your help, i’ve been trying to figure out this question for ages

Most detailed answer:

Answer by kidachan
alerighty so a 1 in 50 chance in apopulation of a hild being born with CF = a 2% abundance in a population (2 out of 100) right? well then their is a 2% chance that the wife has the dangerous allele

the clid would definatly recive for sure one recive allele from the father and then would have about a 2 percent chance of gettiing the allel from the mother which would give the child a 2% chance of coming down with cf

if this were a real situatio i would recomend that the mother looks into her family back ground to see if any of her family members have had the dangerous dease at all for as far back as she can trace it

Question posed by Remi: What can be done to improve the immune system of a Cystic Fibrosis patient?
My boyfriend has cystic fibrosis. We are very blessed in that he has a mild case, but any tips to improve general health (besides the medicines that he gets from his doctor) would be great- we’ve looked into massage therapy, we exercise regularly, eat well…understandably, though, the more benefits we can reap from diffrent “treatments” the better- I want him to be around as long as possible, as healthy as possible.

Most comprehensive answer:

Answer by SnuffySmith
Keeping in good shape with good diet and exercise is one of the best treatments. A drier climate with less humidity is also better on the lungs. Good luck to him.

A question from wzerocx: Biology Cystic Fibrosis Question?
Cystic fibrosis is caused by an abnormal chloride channel protein that makes up part of the cel membrane, HOw might a defect in portein folding cause the cystic fibrosis phenotype at the cellular level?

My chosen answer:

Answer by gregakendall
Cystic fibrosis is a genetic disorder that causes a defect in the chloride-ion channel protein which is embedded in the cell membrane. The faulty protein prevents the cell from regulating its transport of chloride ions across the membrane. The buildup of chloride ions outside the membrane causes very thick mucous deposits to occur, which leads to all the other symptoms of CF.
