What is CF?Cystic Fibrosis is an inherited disease. It causes thick mucus to get stuck in your lungs causing

lung disease. This disorder can kill you.

Some Symptoms Include…

• Excessive coughing• Wheezing • Bronchitis• Chronic sinusitis• Asthma • Salty sweat/skin• Clubbed fingers (deformed)• And more

Symptoms vary from patient to patient.

• Cystic Fibrosis is caused by a mutation in the gene of Chromosome 7, so it is not a sex-linked disorder.

• There are more than 1,000 mutations including salty skin, lung infections and more deformities.

• It contains the information for the cystic fibrosis transmembrane conductive regulator gene (CFTR). that can cause CF.

• The CF is recessive allele.

These are all of the normal chromosomes found in humans.

The Life Expectancy Of A Person with Cystic Fibrosis

The life expectancy has increased due to more tests and better research. Scientists know more about why it occurs and how to manage it.

More tests and accuracy have been discovered making it easier to identify the disease.

• There are about 1,000 new cases each year. • 70% of all people with cystic .fibrosis are diagnosed

by the age of two. • 45% of the patient population is age 18 or older.

This picture shows how if you only have one

faulty CFTR gene you become a carrier and if you have

2 faulty genes you will have

cystic fibrosis.

• CF is most often diagnosed by a sweat test which measure the amount of salt in their sweat. A reading of more than 60 mmol(millimoles) of salt means that the person has two CFTR genes.

• Genetic testing can also diagnose this condition.

Tested and Diagnosed

This is a picture of the digital chloridometer the machine used to measure the amount of salt in your sweat.. This person does not have the cystic fibrosis gene.

This shows the mutation in Chromosome 7 versus the normal chromosome 7.

This picture shows how some of the organs can be affected by Cystic Fibrosis.
