I used to do a level Biology and saw this question and thought I recognised it. the CFTR gene is something to do with cystic fibrosis.
the simple answer is no. The CFTR gene is not in everyone. roughly 25% of the worlds population do have it though. however as it is a recessive alleule you need two genes (both parents) for it to become dominant in someone (their child)
This may not be entirely correct it could be that everyone has it but some are mutated versions. I cant remember entirely. :S

How gene therapy might be used to treat cytic fibrosis?
Gene therapy for cystic fibrosis involves delivering a functional copy of the CFTR gene to affected cells in order to restore normal function of the protein. This can be achieved by using viral vectors to deliver the gene into the cells and allow it to produce normal CFTR protein. By correcting the underlying genetic defect, gene therapy holds promise for treating cystic fibrosis at the molecular level.
Which is a genetic disorder that gene therapy may correct?
Cystic fibrosis is a genetic disorder that gene therapy may correct by introducing a healthy copy of the CFTR gene into cells to restore normal function in affected individuals.
What happens to the CFTR gene in cystic fibrosis and how does it contribute to the development of the disease?
In cystic fibrosis, mutations in the CFTR gene cause it to produce a faulty protein. This protein is unable to regulate the flow of salt and fluids in and out of cells, leading to the buildup of thick, sticky mucus in various organs. This mucus clogs the airways, digestive system, and other organs, causing breathing difficulties, digestive problems, and other symptoms characteristic of the disease.
What are genetic disorders that involve more than one defective gene?
Some examples of genetic disorders involving more than one defective gene are cystic fibrosis, which is caused by mutations in the CFTR gene and other modifier genes; and certain types of neurofibromatosis, which result from mutations in both the NF1 and NF2 genes. These disorders demonstrate the complexity of genetic inheritance and the interactions between multiple genes.
What is one of a mutation that produces a harmful trait?
Hemophilia.
Does cystic fibrosis have extra chromosomes?
No, cystic fibrosis is caused by mutations in the CFTR gene, not by the presence of extra chromosomes. Individuals with cystic fibrosis inherit two faulty copies of the CFTR gene, one from each parent, which leads to the production of a defective CFTR protein that affects the movement of salt and water in and out of cells.
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.
Is cystic fibrosis caused by a gene mutation or chromosomal mutation?
Cystic fibrosis is primarily caused by mutations in the CFTR gene, which is located on chromosome 7. These mutations can result in a defective or non-functioning CFTR protein, leading to the characteristic symptoms of the disease.
What does a CFTR gene stand for?
CFTR gene stands for Cystic Fibrosis Transmembrane Conductance Regulator gene. It is responsible for encoding a protein that regulates the flow of ions across cell membranes, particularly in the lungs and digestive system. Mutations in this gene can lead to cystic fibrosis, a genetic disorder affecting the lungs and digestive system.
What change causes the protein CFTR fold improperly?
A mutation in the CFTR gene causes the protein CFTR to fold improperly. This mutation results in a defective CFTR protein that cannot function properly, leading to the development of cystic fibrosis.
What role does cftr play in the body?
The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane regulator.
Is cystic fibrosis chromosomal abnormality?
Yes, it is caused by a mutation in the gene for the protein CFTR.
If someone was heterozygous for cystic fibrosis what proteins would they make?
If someone is heterozygous for cystic fibrosis, they have one normal CFTR gene and one mutated CFTR gene. This means they would produce both functional and dysfunctional CFTR proteins. The presence of the normal CFTR protein may be sufficient to mitigate the severity of symptoms associated with cystic fibrosis, as they can still have some normal chloride ion transport. However, the overall function and effectiveness of the CFTR protein may be reduced compared to someone with two normal alleles.
In cystic fibrosis a change in a single gene causes the protein called CFTR to?
fold improperly
In cystic fibrosis a change in a single gene caused the protein called CFTR to?
fold improperly
How many exons are in CFTR?
The CFTR (cystic fibrosis transmembrane conductance regulator) gene contains 27 exons. These exons encode the protein responsible for regulating chloride ions across epithelial cell membranes, and mutations in this gene are associated with cystic fibrosis.
How many introns are in CFTR?
The CFTR gene has 27 exons and 26 introns. Introns are non-coding sequences that are spliced out during mRNA processing, while exons are coding sequences that are retained in the final mRNA transcript.
