Cystic fibrosis patients dating other cystic fibrosis patients
According to estimates, approximately 7 to 10 million cystic fibrosis carriers exist in the United States who are totally unaware that they carry a mutated A white American couple with no family history of cystic fibrosis has a 1 in 2500 chance of having a child with cystic fibrosis.
As mentioned earlier, the gene for cystic fibrosis is on the long arm of chromosome 7.
After chloride leaves the cells, water follows and thins the mucus.
However, if the CFTR protein has been damaged, as in cystic fibrosis, the chloride ions are not allowed out of the mucus-producing cells.
Patients with lower FEV levels to trigger the hypoxic ventilatory drive, although they still need adequate oxygenation.
The gene was identified in 1989 and is found at 7q31.2, the long arm (q) of chromosome 7 at position 31.2.
Typical clinical manifestations of cystic fibrosis usually do not occur in patients who have 10% or more generally have a more classic type of cystic fibrosis; however, no definitive correlation exists between the genotype and the phenotype.
In patients with 1% or less functioning of the gene, the patients’ cells have very defective Most patients with manifestations of cystic fibrosis have parents who do not have cystic fibrosis but are heterozygotes or carriers of the disease.
Pulmonary function testing is a method that may be helpful in establishing data that will assist in predicting deterioration in clinical status in patients with cystic fibrosis.
The increased work of breathing can include any of the following: tachypnea, irregular breathing pattern, diaphoresis, flared nares, pursed lip breathing, intercostal muscle retractions, and use of accessory muscles.
gene have a clinical phenotype representative of pancreatic disease, severe pulmonary disease, gastrointestinal problems, and infertility (in men) or, sometimes, fertility problems (in women).
