At most, a point mutation will cause a single amino acid in a protein to change. While this usually is not a deadly mutation, it can cause issues with that protein's folding pattern and the tertiary and quaternary structures of the protein. One example of a point mutation is Sickle Cell Anemia.
Hives, or urticaria, are a common allergic reaction in which a rash or welts appear on the skin. Hives are typically quite itchy and can last just a few minutes or several days before going away. Occasionally, however, these annoying blotches can indicate more serious problems, especially when accompanied by symptoms such as difficult breathing.
Urticariaâthe scientific name for hivesâis an outbreak of red, swollen, and itchy welts that form on the skin. Hives appear suddenly and can appear anywhere on the body, including the face, lips and throat. They typically vary in size, and may join together to form larger welts.
