    en.wikipedia.org/wiki/Cystic_fibrosis

    Cystic fibrosis (also known as CF or mucoviscidosis) is an autosomal recessive genetic disorder affecting most critically the lungs, and also the pancreas, liver, and intestine.

  3. Cystic fibrosis transmembrane conductance regulator - Wikipedia

    en.wikipedia.org/wiki/Cystic_fibrosis_trans...

    Cystic fibrosis transmembrane conductance regulator. Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and anion channel in vertebrates that is encoded by the CFTR gene. [5][6] Geneticist Lap-Chee Tsui and his team identified the CFTR gene in 1989 as the gene linked with CF (cystic fibrosis). [7]

  4. Cystic fibrosis and race - Wikipedia

    en.wikipedia.org/wiki/Cystic_fibrosis_and_race

    Cystic fibrosis (CF) is an autosomal recessive and monogenetic disorder. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. [3] The CFTR protein (Figure 1) serves to move chloride ions to the surface of cells to ensure proper hydration. When this protein becomes dysfunctional, the chloride ions are ...

    en.wikipedia.org/wiki/Heterozygote_advantage

    As of 2016, the selective pressure for the high gene prevalence of CF mutations is still uncertain, and may be due to an unbiased genetic drift rather than a selective advantage. Approximately one in 25 persons of European descent is a carrier of the disease, and one in 2500 to 3000 children born is affected by Cystic fibrosis.

  7. Frameshift mutation - Wikipedia

    en.wikipedia.org/wiki/Frameshift_mutation

    Cystic fibrosis (CF) is a disease based on mutations in the CF transmembrane conductance regulator (CFTR) gene. There are over 1500 mutations identified, but not all cause the disease. [21] Most cases of cystic fibrosis are a result of the ∆F508 mutation, which deletes the entire amino acid.

  8. Genetic disorder - Wikipedia

    en.wikipedia.org/wiki/Genetic_disorder

    A genetic disorder is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality. Although polygenic disorders are the most common, the term is mostly used when discussing disorders with a single genetic cause ...

  9. Nonsense mutation - Wikipedia

    en.wikipedia.org/wiki/Nonsense_mutation

    Nonsense mutation. In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a nonsense codon, or a premature stop codon in the transcribed mRNA, and leads to a truncated, incomplete, and possibly nonfunctional protein product. [1] Nonsense mutations are not always harmful; [2] the functional effect of a nonsense ...
