What is Cystic Fibrosis
-A hereditary disorder
-Makes glands secrete a
sticky mucus which
clods the pancreas,
liver, and intestines .
-Infection of the lungs

Cystic Fibrosis Inheritance





Both parents can carry the gene
Occurs right after birth
Child has 25% chance of getting Cystic
Fibrosis if both parents are heterozygous
carriers and 50% of being a carrier
Abnormal recessive gene
Both parents need to be carriers in order
for the off spring to inherit Cystic Fibrosis

Cystic Fibrosis Frequency

1/25 of all Caucasians carry this disease

-Because of sticky mucus, the
pancreas is clogged, which
impairs digestive enzyme flow
to intestines, which minimizes
the patient, potential to digest
food and harvest nutrients
-Sticky mucus also creates a
layer around the lungs makes
it harder for patient to breath,
especially during cardio
activates
-Average life expectancy of
persons with Cystic Fibrosis:
about 30 years
How is it Diagnosed?
Usually discovered in early childhood
 Simple procedure, where the patient is
tested for excessive levels of sodium
chloride in their sweat

How is this Disease Treated?




It is possible to extract the pancreas, to
overcome the lack of digestive enzyme flow
Daily back slapping is in order, because it
helps break up the mucus.
Gene Therapy- It is possible to inject a
normal, healthier gene into the patient. This
therapy has had high hopes from scientists,
but has shown no positive results yet.
Currently, there are a few known antibiotics
that have proven to increase one’s life
expectancy
Is There a Cure?

There is no known cure, but scientists
everywhere are striving to produce one
for this disease. There is a foundation for
this disease, which raises money for aid to
the current patients, and for finding a
cure in the near future
SMaRT Therapy

A type of gene therapy, which takes
advantage of the need to remove introns.
This makes a functional mrna, so genes
will continue to reduce possibility of the
patient’s child getting the disease
