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.
The underlying defect in cystic fibrosis is an improperly folded CFTR (cystic fibrosis transmembrane conductance regulator) protein. Depending on the type of mutation, the misfolded CFTR protein either doesn't reach the cell membrane or reaches the cell membrane but doesn't function properly. CFTR is responsible for regulating transport of chloride and sodium ions into and out of cells. The movement of these ions is crucial in helping to control the movement of water in tissues which is what helps thin mucus. Without properly functioning CFTR the mucus becomes thick and sticky. This viscous mucus builds up in and clogs organs.
Cystic Fibrosis is an autosomal, recessive phenotype, meaning that two copies of the allele must be inherited to produce the disease. The gene for CF is found on chromosome 7.
CF (Cystic Fibrosis) is usually found on chromosome 7.
Cystic fibrosis is a homozygous recessive disorder.
Cystic fibrosis is sex linked.
It is the gene for cystic fibrosis. CFTR means Cystic Fibrosis Transport Regulator.
No cystic fibrosis is caused by a mutated CFTR gene.
Cystic fibrosis (CF) is an autosomal recessive disorder, not an X-linked disorder. It means that both copies of the gene responsible for CF need to be mutated in order to develop the disorder. Incomplete dominance refers to a genetic trait where the heterozygous condition results in an intermediate phenotype, which is not the case for CF.
Cystic Fibrosis
Cystic fibrosis is not an infectious disease but a genetic disease, provoked by mutations fo the CFTR gene, mainly inherited.
Cystic Fibrosis is a genetic disorder, 2 parents have a CF gene, if their offspring inherits that trait they will have Cystic Fibrosis.
Cystic Fibrosis is recessive. If you have one CF gene and one non-CF gene, you will be a carrier but not have CF.
Polygenic means influenced by multiple genes. Cystic fibrosis is a single gene disorder, in which a mutation occurs in one gene that specifies cystic fibrosis, in this case CFTR gene. There are thousands of possible mutations in this gene but the most common mutation is the deletion of one codon.
cystic fibrosis
Cystic Fibrosis, is a recessive disease (meaning that both parents must be carriers of the cystic fibrosis gene, for the offspring to have a chance of being born with it). A child has a 25% chance (1/4) of being born with Cystic Fibrosis.
No, cystic fibrosis is an autosomal recessive disorder.
It is the gene for cystic fibrosis. CFTR means Cystic Fibrosis Transport Regulator.
It is autosomal recessive and it is not a disorder! Cystic Fibrosis is a disease.
Cystic Fibrosis
No cystic fibrosis is caused by a mutated CFTR gene.
Gene therapy has shown promise in controlling Cystic fibrosis.
Yes, because it is "autosomal recessive hereditary disorder".
