Cystic Fibrosis Gene Carrier
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
Yes: It is a recessive trait, so both have to have the gene to pass it to a child. ...Read more
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.
50-50: One half of offspring will be carriers and one half will not be carriers. No offspring will be afflicted. Thanks for trusting HealthTap! ...Read more
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
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 moreSee 1 more doctor answer
Is there a resource out there that discusses the different cystic fibrosis gene mutations & which symptoms are associated with each one?

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
