WebStep 2/2. Final answer. Transcribed image text: One medical condition showing promise with CRISPR-Cas9 treatment is sickle-cell disease. A mutation in the HBB gene, which codes for beta-globin, causes abnormal hemoglobin to be produced in blood cells. This distorts red blood cells into an abnormal sickle shape and causes clumping, leading to ... WebSickle cell anemia is caused by mutation of a single base in the DNA sequence of the ß-globin gene (HBB).

Hemoglobin synthesis is impacted by sickle cell disease (SCD), a hereditary illness that inhibits red blood cells' ability to transport oxygen throughout the body. Red blood cells with SCD develop a stiff sickle shape and an aberrant hemoglobin molecule, which can obstruct blood flow, harm tissues, and cause discomfort.
