Doctor insights on: Cystic Fibrosis Gene Carrier

Share

Genetic (Definition)

From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more

Do both parents have to be cystic fibrosis gene carriers for their child to get it?

Do both parents have to be cystic fibrosis gene carriers for their child to get it?

Yes: It is a recessive trait, so both have to have the gene to pass it to a child. ...Read more

Can a carrier of the Cystic Fibrosis gene ever be symptomatic?

Can a carrier of the Cystic Fibrosis gene ever be symptomatic?

Autosomal recessive: CF is an autosomal recessive genetic disorder. Complete expression of the disease (symptoms) do not typically occur in people who do not have both copies of the defective gene (carriers only have one). ...Read more

What are the chances of passing on the Cystic Fibrosis gene if only one parent is a CARRIER? Other parent not a carrier.

What are the chances of passing on the Cystic Fibrosis gene if only one parent is a CARRIER? Other parent not a carrier.

Cystic fibrosis is a disorder of genes but which ones?

Cystic fibrosis is a disorder of genes but which ones?

CF gene mutations: There are currently more than 1900 mutations that are known to cause cf. About 70% of CF pts in us have deltaf508 mutation, as 1 in every 25 persons is a carrier for this mutation. All these mutations result in abnormal activity of a protein called cftr which causes all the CF related problems. Genetic testing can give the specific mutation each pt has. Talk to your local CF center. ...Read more

How can the cystic fibrosis gene affect tuberculosis?

How can the cystic fibrosis gene affect tuberculosis?

Lung Function: The gene itself will not affect tuberculosis. However, if an individual receives 2 recessive genes of the cftr mutation from their parents, they will develop cystic fibrosis (cf). Because CF can lead to repeated bacterial lung infections (among other things), the lungs would already be in a weakened state if exposed to the causative agent of tuberculosis. This might lead to faster disease onset. ...Read more

Cystic fibrosis disease is carried by a recessive allele on which gene?

CFTR: Cystic fibrosis is caused by a mutation of the cftr gene, or cystic fibrosis transmembrane regulator, on chromosome 7. Cftr works as a chloride ion channel which helps to regulate chloride and sodium movement in your lungs and sweat ducts. ...Read more

Can you explain if it's possible to get cystic fibrosis without carrying the genes for it?

Can you explain if it's possible to get cystic fibrosis without carrying the genes for it?

No: Cystic fibrosis (CF) is a genetically inherited disease, so CF or cf-related disease (atypical cf, crms) rely on having at least 1 inherited gene. The other part of CF diagnosis is having an elevated sweat chloride. It is possible to have a positive sweat chloride due to other circumstances (thyroid imbalance, trisomy 21), but without CF genetics, there cannot be a diagnosis of cf. ...Read more
