Jan 9, 2023 · Sickle cell disease (SCD) is one of the most common hemoglobinopathies, which comprises a group of disorders that are characterized by faulty hemoglobin production ( 1, 2 ). Hemoglobin, a two-way respiratory carrier in red blood cells (RBCs), is responsible for transporting oxygen to tissues and returning carbon dioxide to the lung. Victoria Gray has sickle cell disease (SCD). SCD is a genetic disease that causes red blood cells to be half moon-shaped instead of round. The sickle-shaped cells block blood vessels, slowing or stopping blood flow. This causes sudden, severe pain. Complications include organ damage, strokes, anemia, and early death.

Sickle cell disease (SCD) is an autosomal-recessive genetic disorder that affects approximately 100,000 people in the United States and millions worldwide (1–3).According to the systematic analysis of the Global Burden of Disease Study (), 3.2 million people live with SCD, 43 million people have sickle cell trait (i.e., are …Sickle cell disease (SCD) is an inherited monogenic disorder resulting in serious mortality and morbidity worldwide. Although the disease was characterized more than a century ago, there are only two FDA approved medications to lessen disease severity, and a definitive cure available to all patients with SCD is lacking. Genome editing using CRISPR-Cas9 has produced a functional cure for a small number of patients with sickle cell disease and beta-thalassemia.
