My pregnant daughter and her fiance have the cystic fibrosis gene. What tests are done to check the baby?

Pre/post delivery ? All states have some form of newborn screening and some include CF testing as part of that panel.Check your state to be sure. They can do gene studies on fetal cells that can be found in mom's blood as early as 8 weeks into pregnancy.This testing was initially designed to verify paternity but can be used to diagnose or exclude a number of conditions in the fetus.Ask the doc for guidance.
Newborn screening. Newborn screening for cystic fibrosis is now standard in all states in the usa. A positive newborn screen for cystic fibrosis is verified by sweat testing or genetic studies (mutation analysis for cf). Approximately 90% of the infants identified by newborn screening will by carriers of the CF gene and only 10% of the infants will have CF with a positive sweat or genetic test.

Doubt your Dx. There is a rare but different disease called fibrocystic disease of the lung.It has nothing at all to do with cystic fibrosis, which is evident in most kids in their first year.For one to live to 82 with the disease would likely be a world record. Read more...
Screening test. Cystic fibrosis is a genetic disease and there are many mutations of the CF gene.. Since CF is part of your family's genetic history, i would suggest screening your children. If your father's exact genetic mutation is known, then the genotype testing should include this in the analysis. Some children are diagnosed with other illnesses such as asthma, when in fact they have cf. Hope this helps. Read more...

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...
