Webb15 juli 2024 · Sickle cell disease is a genetic disorder caused by mutation in the beta globin genes that leads to faulty hemoglobin protein, called hemoglobin S. Hemoglobin S changes flexible red blood cells into rigid, sickle-shaped cells. These sickle cells can block blood flow, and result in pain and organ damage. WebbSickle cell anemia: a look at the connection between DNA and phenotype. Genes are translated into proteins; mutations often (but not always) result in changes in the sequence of amino acids in those proteins. Changes in the amino acid sequence can modify (in various ways) or even completely destroy protein function.
