Cystic fibrosis, is it sexlinked?

Cystic fibrosis, is it sexlinked?

Autosomal recessive.: Cystic fibrosis (CF) is not sex-linked, but autosomal recessive. That means both parents can be silent carriers--totally unaware--then each passes down this recessive (inactive) gene to their child. This child develops CF because both copies of the formerly inactive gene (1 from each parent) now have no genetic "brake" (normal dominant gene) to prevent the CF gene from expressing itself. ...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

Are cystic fibrosis and diabetes related?

In a way: Most patients with diabetes have either a failure of the pancrease (pancrelipase) to produce Insulin or develop resistance to Insulin for various reasons. In cf, there is pancreatic insufficiency due to injury to the pancrease (pancrelipase) from the disease itself... And this can lead to CF related diabetes (where more Insulin is needed). ...Read more
