What are the specific DNA changes that produce the abnormal cystic fibrosis protein?
Cystic fibrosis is primarily caused by mutations in the CFTR gene, which encodes the cystic fibrosis transmembrane conductance regulator protein. The most common mutation is a deletion of three nucleotides that results in the loss of phenylalanine at position 508 (ΔF508). This misfolding prevents the protein from reaching the cell surface, leading to impaired chloride ion transport. Other mutations can also disrupt the protein's function or stability, contributing to the disease's pathology.

What is cystic fibrosis gene disorder?
The genes on each chromosome control specific functions of the human body. The gene on chromosome 7 produces a protein called cystic fibrosis transmembrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease. It means that both copies of the gene must be defective. An affected person will have abnormal cystic fibrosis transmembrane regulator gene on each chromosome 7. Therefore both biological parents must have an abnormal gene. One abnormal copy is inherited from each parent. A person with one normal gene and one abnormal gene is called a cystic fibrosis carrier. Cystic fibrosis carriers do not show any symptoms but they may pass the abnormal gene to their children. Therefore the parents can be either cystic fibrosis carriers or affected themselves.

What characteristics does an abnormal external sphincter electromyography have?
A diseased external sphincter muscle will produce an abnormal pattern of electrical activity.
A disorder in which the body produces abnormally thick mucus in the lungs and intestines is called?
Cystic fibrosis is a genetic disorder that causes the body to produce thick and sticky mucus in the lungs and digestive system. This can lead to respiratory problems, digestive issues, and other complications. Early diagnosis and management are crucial in improving quality of life for individuals with cystic fibrosis.
What causes certain glands to produce excessive mucus saliva and sweat?

How can genetic engineering improve cystic fibrosis?
They isolated functional CFTR gene. Then they inserted the CFTR gene into nondisease-causing adenovirus virus. Last, they infected the patient´s airway cells with virus carryinhg the healthy CFTR gene.

In most men with CF (95%), the tubes that carry sperm are blocked, which causes infertility.

What other diseases are caused by cystic fibrosis?
Cystic fribrosis is an inherited disease of the secretory glands, including the glands which produce sweat and mucus.
