Sickle cell disease is a genetic disorder that\u2063 affects hemoglobin, causing the\u2063 production of abnormal, sickle-shaped red blood cells.\u2062 This condition \u200bcan \u2062lead to severe pain episodes, anemia, infections, and complications such as strokes and organ damage.<\/p>\n<p>The potential of exa-cel to offer a cure for sickle\u2063 cell disease is \u200dundeniable.\u200c This\u200d gene editing \u2064treatment has the potential to correct \u2064the genetic mutation responsible for the disorder, providing an opportunity for individuals with sickle cell disease to lead healthier lives.
