How can cystic fibrosis affect fetal development?

How can cystic fibrosis affect fetal development?

Not usually apparent: Cystic fibrosis patients are occasionally born with such thick poo that it is stuck & may result in surgical treatment. However, most have no visible findings at birth that would suggest a problem. During pregnancy, the maternal system handles the majority of metabolic challenges, nutrition (placenta), and the issues that may cause failure to thrive in CF only come into play after birth. ...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 idiopathic pulmonary fibrosis cystic fibrosis the same?

Are idiopathic pulmonary fibrosis cystic fibrosis the same?

No: Two completely different diseases. CF is an inherited disorder leading to failure to clear mucus and repeated infections. It does end up with fibrosis in the lungs. Idiopathic fibrosis is a disease of unknown cause where scar tissue replaces normal lung and eventually causes respiratory failure. ...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

Does chorionic villi sampling determine whether a fetus has genetic abnormalities?

Does chorionic villi sampling determine whether a fetus has genetic abnormalities?

Yes and no: Chorionic villi sampling is a procedure where a small sample of cells from the placenta are removed, early in a pregnancy. A lab can determine if there are any extra or missing chromosomes, or large parts of a chromosome that are extra or missing. Other tests on chorionic villi can look for abnormalities in single genes, but no test can determine that a baby has no genetic abnormalities. ...Read more

Is pulmonary fibrosis the same as cystic fibrosis?

Is pulmonary fibrosis the same as cystic fibrosis?

No: Cystic fibrosis is a genetic disease causing abnormal functioning of the mucus glands in the lung and leading to recurrent infections. Pulmonary fibrosis is a disease of progressive scarring causing loss of alveolar units that can have a variety of causes. ...Read more

Is pulmonary fibrosis inherited?

Is pulmonary fibrosis inherited?

Pulmonary fibrosis: While I have not seen it commonly there are some families with a history of pulmonary fibrosis. Most of my office patients and previous fibrosis patients I have come across are the only ones in their family with fibrosis. I have one patient in my practice with several family members with progressive and ultimately fatal fibrosis. She has been evaluated at duke university with a genetic workup. ...Read more

Can babies with cystic hygroma survive long?

Can babies with cystic hygroma survive long?

Yes.: This is a congenital multiloculated lymphatic lesion that can arise anywhere. It is classically found in the left posterior triangle of the neck, and contains large cyst like cavities withy watery fluid. This is benign, but a lethal version, cowchock wapner kurtz syndrome, causes cystic hygroma, lymphedema and cleft palate. This can be seen in adults, and people can live normal lives. ...Read more

Is CTFR gene the same as being aCystic Fibrosis Carrier?

Is CTFR gene the same as being aCystic Fibrosis Carrier?

Not necessarily: The CFTR gene, or mutations in this gene, are what are often being tested for in patients suspected of being cystic fibrosis carriers or suffering from the disease itself. If you are a carrier then you will have one copy of your CFTR gene with an abnormality. ...Read more

Prenatal testing for cystic fibrosis available?

Yes. Talk to OB.: Cystic fibrosis is an inherited genetic disorder. Prospective parents can be tested to see they are carriers and discuss with genetic counselor the chance of having child with CF if one/both are carriers. Post-conception testing is also available. Talk to your ob. Here's link for additional info: http://www.Acog.Org/~/media/for%20patients/faq171.Pdf?Dmc=1&ts=20120518t1505423920. ...Read more

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
