  2. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    An example of a disease that is caused by a dominant lethal mutation is Huntington's disease. Null mutations, also known as Amorphic mutations, are a form of loss-of-function mutations that completely prohibit the gene's function. The mutation leads to a complete loss of operation at the phenotypic level, also causing no gene product to be formed.

  3. Germline mutation - Wikipedia

    en.wikipedia.org/wiki/Germline_mutation

    Other examples include mutations in the BRCA1 and BRCA2 genes which predispose to breast and ovarian cancer, or mutations in MLH1 which predispose to hereditary non-polyposis colorectal cancer. Huntington's disease. Huntington's disease is an autosomal dominant mutation in the HTT gene.

  4. Frameshift mutation - Wikipedia

    en.wikipedia.org/wiki/Frameshift_mutation

    Mutations in the Troponin C gene are a rare genetic cause of hypertrophic cardiomyopathy. A recent study has indicated that a frameshift mutation (c.363dupG or p.Gln122AlafsX30) in Troponin C was the cause of hypertrophic cardiomyopathy (and sudden cardiac death) in a 19-year-old male.

  5. 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 ...

  6. Mutation rate - Wikipedia

    en.wikipedia.org/wiki/Mutation_rate

    The human germline mutation rate is approximately 0.5×10 −9 per basepair per year. [1] In genetics, the mutation rate is the frequency of new mutations in a single gene, nucleotide sequence, or organism over time. [2] Mutation rates are not constant and are not limited to a single type of mutation; there are many different types of mutations.

  7. Point mutation - Wikipedia

    en.wikipedia.org/wiki/Point_mutation

    A point mutation is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome. [1] Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.

  8. Somatic mutation - Wikipedia

    en.wikipedia.org/wiki/Somatic_mutation

    Somatic mutation. A somatic mutation is a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte. Unlike germline mutations, which can be passed on to the descendants of an organism, somatic mutations ...

  9. Missense mutation - Wikipedia

    en.wikipedia.org/wiki/Missense_mutation

    Missense mutation refers to a change in one amino acid in a protein, arising from a point mutation in a single nucleotide. Missense mutation is a type of nonsynonymous substitution in a DNA sequence. Two other types of nonsynonymous substitution are the nonsense mutations, in which a codon is changed to a premature stop codon that results in ...
