Cystic Fibrosis
By Patrick Nelson, Chris Rehm,
and Grayson Smith
How Cystic Fibrosis is Inherited
• Cystic Fibrosis is a disease that is transmitted
through genes.
• It is an autosomal recessive disorder.
Carriers
• It is possible for one to be a carrier for Cystic
Fibrosis.
• Cystic Fibrosis can diagnosed when one is very
young.
• It is protocol for some states to test for CF on
every newborn child.
Testing
• Recent studies have shown that many children
who have been diagnosed with Cystic Fibrosis
have had an early onset of defective bone
mineralization in the lumbar spine, which is
located between the ribs and pelvis. Many doctors
now use this to test for Cystic Fibrosis.
Frequency of Disease
• Cystic Fibrosis (commonly known as CF), is most
common in Caucasians
• Caucasians: 1 in 3,000
• African-Americans: 1 in 17,000
• Asian-Americans: 1 in 31,000

Cystic Fibrosis
Symptoms of Cystic Fibrosis
Symptoms include:
• Body creating thick, sticky mucus that clogs
the lungs and obstructs the pancreas.
• This can cause the body to become
dysfunctional because these vital organs are
blocked.
Treatment
• The treatments for CF include antibiotics
and medication to dilate air passages in the
body, chest physiotherapy, where mucus is
drained from the lungs, and even lung
transplantation for the most severe patients.
Example of CF Antibiotics
Prevention of CF
• Unfortunately there is no known cure for CF.
• However, scientists do have a prevention that is a
prompt nutritional which prevents many of the
secondary problems that occur because of
malnutrition.
• These have shown improved lung function later in life
of CF patients.
