Summary: What Is Cystic Fibrosis?
THE FACTS ABOUT CYSTIC FIBROSIS
Cystic Fibrosis
What is Cystic Fibrosis
When asked what is cystic fibrosis, I mainly answer that the body is not able to get rid of mucus that it produces. Mucus is made up of proteins, water, mucus cells, or the squishy kind of cells, plus white blood cells exported from the immune system.
The role of mucus as a symptom of Cystic Fibrosis
Here you will notice that mucus is part of the response of the
immune system to protect the body, much like diarrhea is used to
expel the poison created by the bad bacteria in your
intestines.
Mucus is produced to lubricate membranes. And it is produced to attack substances your body perceives as harmful. We naturally have the ability to deal with and get rid of an awful lot of mucus — even a quart a day, believe it or not.
But not if we have cystic fibrosis.
What you have or will not have is the ability to break down all that gooey, sticky stuff naturally. Even if the germ or allergic substance threat has been eliminated, your body will still have that mushy stuff. And it’s not just the feeling, and it’s nothing like a high school infatuation.
That mucus will block your lungs, preventing you from breathing properly. It will block your pancreas and prevent those good digestive juices from reaching your duodenum and stomach.
If the mucus is produced in your digestive tract, it can even prevent you from getting the right nutrients from the food that you eat. The thick mucus may prevent the minerals and vitamins from being absorbed into the bloodstream and then delivered to all the cells in your entire body.
Is Cystic Fibrosis Curable?
Physicians believe that there is no cure. When asked what is cystic fibrosis going to do to a person’s lifespan, they answer that a cystic fibrosis patient will have little chance of surviving for 30 years. But let me talk to you about the oxygen remedy, which will help your body break up that mucus, without you having to spit it out for 15-25 minutes at a time. It has worked for cystic fibrosis without pills, fancy supplements, or anything expensive.

AP Biology Homework Help About Cystic Fibrosis?
A question from Lorry Gregory: AP Biology homework
help about Cystic Fibrosis?
Cystic fibrosis can be caused by any one of several mutant
alleles of the cystic fibrosis gene. The most common of these
mutants alleles accounts for about 70% of cases of cystic
fibrosis. The use of gene probes can identify individuals
carrying this allele. Gene probes are single strands of DNA which
are radioactively labelled. They have a base sequence that is
complementary to a mutant allele. The main stages in using a gene
probe are shown in the diagram.
Sample of DNA extracted from a person’s tissue and heated to
separate the strands.
Radioactive gene probe is added to the DNA.
Excess probe is washed away.
Sample is tested for radioactivity.
Using the information given, explain how the use of a gene probe
could enable the presence of a mutant allele of the cystic
fibrosis to be detected.
Chosen answer:
Answer by Horst S
With your approach, you can only identify those mutations that
you actually test for.
You take a sample of your extracted DNA and separate it into
various aliquots. Each aliquot is individually hybridized with a
probe specific for each mutation. This can be done by Southern
Hybridization. You will get a signal when your sequence binds
(hybridizes) with the probe. No signal means that mutation is
absent – the probe could not bind.

What Is the Ethnic Group Affected by Cystic Fibrosis?
A question asked by cnaines: What is the ethnic
group affected by Cystic Fibrosis?
an inherited/ genetic disease that …..source
http://www.cff.org/AboutCF/Faqs/#Who_gets_cystic_fibrosis?
Cystic fibrosis is an inherited disease that causes thick, sticky mucus to build up in the lungs and digestive tract. It is the most common type of chronic lung disease in children and young adults, and may result in early death
Chosen answer:
Answer by Mariah
White, European descendents mostly get the disease, although
there are always a small percent of other ethniticities that get
it.

Cystic Fibrosis in Newborns? Do You Have a Child With CF?
A question asked by milelj79: Cystic Fibrosis in
newborns? Do you have a child with CF?
Cystic fibrosis in newborns? Do you have a child with CF?
My daughter will be two weeks old tomorrow. We got a call from
the pediatrician today that her newborn screening tests came back
and she needs to go having further screening to test for cystic
fibrosis. Did anyone have to do this and have the tests come back
negative that they don’t have it? Neither me or my husband have a
family history of CF, so this was a surprise. I’m very worried
and hoping it’s a false alarm.
Does anyone have a child with CF? What symptoms did they have as a newborn?
I did read about CF online, but am curious about what other people have experienced with their babies.
Thanks for any information you have.
The No 1 answer:
Answer by E M
Here’s a link I found about the testing.
http://www.cysticfibrosismedicine.com/htmldocs/CFText/screen.htm
And here’s a very good article all about it
http://children.webmd.com/tc/Cystic-Fibrosis-Topic-Overview
I hope your daughter is ok!
In order for your child to have CF, both parents have to be a carrier of CF. If only one parent is a carrier, the child will not have CF. They must inherit it from both parents.

Infertile Couple Denied Fertility Treatment?
A question from jf92509: Infertile Couple Denied
Fertility Treatment?
I have to do a mock trial surrounding an actual case involving a
doctor that denied an infertility treatment to a couple in which
both the male and female were infertile and they were carriers of
cystic fibrosis. He denied doing the treatment because he said
“nature didn’t intend for them to have a child”. The couple
decided to sue for descrimination. My instructor said that the
case is Patterson vs. Katz, but I’m not sure if he changed the
name or not. If anyone can point me in the direction of the
actual (or similar) case details, I would be forever grateful!
Thank you!

You might have better luck asking in the legal section. Why would
your teacher not give you the case that this is based on???

Answer by Hattie
Yes, sorry to say it bluntly though! Try not to worry, I’m sure
they will be fine, and even if the news is that they have CF,
there are plenty of helping hands out there. Your not on your
own, so don’t worry!
Hope your both okay!

In Finland, the Frequency of Heterozygous Carriers of Cystic Fibrosis Is 1/80.?
A question asked by toni.chang: In Finland, the
frequency of heterozygous carriers of cystic fibrosis is
1/80.?
In Finland, the frequency of heterozygous carriers of cystic
fibrosis is 1/80. In a small Finnish city there is a Swedish
immigrant community in which the heterozygous carrier frequency
for cystic fibrosis is 1/22. What is the probability that a child
born to a Finnish mother and a father from this Swedish
population will suffer from the disease?
Chosen answer:
Answer by Peter S
1/80 x 1/22 = 1 in 1760
