Cf (Cystic Fibrosis)
Progressive disease: Cystic fibrosis (CF) is a progressive, lifelong condition in which the glands that produce mucus, sweat, and intestinal secretions do not function properly. Thick mucus accumulates in the lungs, leading to breathing difficulty and infection. CF also impairs digestion, and affected males are usually infertile. ...Read moreSee 1 more doctor answer
Can men with atypical cystic fibrosis have children? I have 2 children, I have no symptoms of CF and I am 32 years old. Never tested for CF.
My son has hirschsprung disease. My wife tested neg. for cystic fibrosis. Are the two related? Should I be tested for CF? I'm 32 w/no issues.
No, not related: Hirschsprung's disease is a congenital condition that leads to absence or lower numbers of nerve cells in the large intestine that are responsible for allowing the colon muscles to function, leading to constipation or inability to pass stool. Cystic fibrosis is an inherited recessive disorder of salt transport leading to thickened secretions. If your wife is negative, no need for you to be tested ...Read moreSee 2 more doctor answers
Newborn boy has a severe mutation delf508 and a 5-t gt12. Was told that he might or might not develop mild cystic fibrosis. How does mild CF manifest?
Varies: Mild CF can vary from recurrent sinus infections, recurrent pneumonia, pancreatitis, fertility problems. One may have no evidence of CF until adulthood. Sometimes the first sign is recurrent pancreatitis in the second or third decade of life. Usually growth is not impaired. ...Read moreSee 1 more doctor answer
My wife & son passed california newborn screening for CF, does that mean odds are low for typical cystic fibrosis or mild form?
Newborn screening : for Cystic Fibrosis is done by Immunoreactive Trypsinogen, IRT. If othe IRT level is ^, DNA tests for CF gene mutations are done on blood on the Guthrie card. CF Foundation-accredited Care Centers in CA look for an "intermediate" sweat chloride result in young infants who do not gain wt. & have bad gas, abdominal pain & loose or hard stools &/or wheezing/coughing for > 2 wks. to diagnose CRMS. ...Read more
Should I be tested for cystic fibrosis? If wife had negative prenatal screening & my son had negative IRT/DNA test (california screening). Curious after reading about CF in adults. Feel fine. anxiety
My son & wife tested neg for Cystic Fibrosis through screening test, not sweat test. However my son has hirschsprung disease. Should I test for CF - or it's high unlikely I have it? I'm 32. Feel fine
I wouldn't: There is no relationship between Hirschprung disease and CF. If you wand to know if you are an asymptomatic carrier of CF, the tests are available. However, you don't get to age 30 without symptoms when you have the disease and your fertility would also be diminished.If your wife is not a carrier, you can not produce babies with CF. ...Read moreSee 3 more doctor answers
My 3 1/2 yr. Old with cystic fibrosis has cold/ allergy symptoms...But unusually grumpy and purple color under eyes...Allergies or CF exacerbation?
Pls see answer: There is an overlap between the symptoms of allergy and cf. Allergic symptoms tend to be associated with a particular exposure that triggers an allergic response. The discoloration under the eyes may be caused by allergies, infection, lack of sleep, iron deficiency. If the area around the eye is red and swollen, it is best to check with your doctor. Fever > 101 is not usual for an allergic resp, . ...Read moreSee 1 more doctor answer
Certainly: Cystic Fibrosis (CF) most common life-limiting genetic disorder of Caucasians, affecting approximately 30K people in the US.A, impacting mainly respiratory function. In recent years patients symptoms better controlled by genetic findings and better medications.Emotional & phys. development depend on severity, time in hospital, complications.Morb. & mort.factors afect emotional,cognitive behavior. ...Read more
As a carrier: Genetic carrier testing: more than 10 million americans are symptomless carriers of the defective CF gene. This blood test can help detect carriers, who could pass CF onto their children. To have cystic fibrosis, a child must inherit one copy of the defective CF gene from each parent. ...Read more
Yes: Yes it is possible. Presentation of cystic fibrosis varies greatly, and it is possible, depending on your specific mutation (and other factors) to present at a later age. In order to prevent late diagnoses, all states now have a newborn screen in place for cystic fibrosis. ...Read moreSee 1 more doctor answer
I have family members with cystic fibrosis. Is it possible to start show the symptoms in my 20's?
What are the chances of a child getting cystic fibrosis among the different racial groups in the u.S.?
Overall 1/3700: Acording to the CF foundation: the overall birth prevalence is 1/3700 . It can occur in any race, however the greatest incidence is in caucasians of northern european descent, being 1/2500. The other major groups affected are hispanics 1/13500, african americans 1/15000. More than 10 million of us carry one part of the defective gene, but to have the disease you must have a copy from both parents. ...Read moreSee 1 more doctor answer
Genetic disorder: It is a genetic disorder characterized by abnormal sodium channels, which affect a great deal of problems including the respiratory and digestive systems. It is most commonly diagnosed in infants failing to gain appropriate weight, and in children who have multiple chronic infections. ...Read moreSee 1 more doctor answer
Inherited disease: Cystic fibrosis (CF) is an inherited disease that affects the cells lining the lungs, sinuses, intestines, spleen and liver. It prevents chloride ions from crossing the cell membranes properly. This can clog organ ducts. In the lungs, the extra mucus crushes the cilia and leads to more lung infections. Medications can help; in late-stage disease, lung transplantation may be life-saving. ...Read more
Depends on genes: The risk of acquiring cystic fibrosis (CF) depends on whether the parents of a child are carriers for the gene. It is estimated that about 1 in 20 americans are carriers of the CF gene. In order for a child to acquire the disease, both parents must be carriers. If both parents are carriers, there is then a 25% chance that the child will acquire the disease. ...Read moreSee 1 more doctor answer
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
Cough, poor growth: Common symptoms of cystic fibrosis include cough, wheeze, recurrent lung infections, poor growth, foul smelling stools, salty sweat, clubbing, and rectal prolapse. The more symptoms the greater the chance of having cystic fibrosis. Most infants today are diagnosed by newborn screening for CF before they develop any symptoms and early therapy can minimize disease symptoms. ...Read more
Variable: This depends on the individual patient. There are several hundred CF mutations that have varying degrees of severity. The most common mutation, df508, can cause failure to thrive in infants, recurrent and very serious lung infections during childhood and often pancreatic insufficiency in children. While early diagnosis and preventive treatment have improved, CF is still a fatal disease. ...Read moreSee 1 more doctor answer
CF is recessive: Cystic fibrosis is a disorder passed thru the genes of both parents, silent in the carrier parent & expressed in the affected kid who has inherited an affected gene from both parents.One mutation(delta 509) is the most common but others occur and variations in intensity do occur. I believe you can have carrier testing to see if u carry a gene, then avoid a starting a pregnancy with another carrier. ...Read more
Recessive gene: A mutation is carried in the dna of both unaffected parents & that matching or similar mutation is paired up at conception when the sperm & egg form completed chromasomes with the defective info. Late in pregnancy and after delivery, the effect of the CF gene abnormality begins to reveal itself. In carriers, the good gene compensates for the bad & no problems occur. ...Read more

Get tested: Testing for cystic fibrosis starts with a sweat test. If that is abnormal, genetic testing in the blood is used to confirm the diagnosis by finding the specific genetic mutations. In general, people with CF have recurrent pulmonary infections and abdominal discomfort/diarrhea due to fat malabsorption. ...Read moreSee 1 more doctor answer
