Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood cells, which causes these cells to assume a sickle shape, especially when under low oxygen tension.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

The only cure for painful sickle cell disease today is a bone marrow transplant. On Tuesday, advisers to the Food and Drug Administration will review a gene therapy for the inherited blood ...
Children with sickle-cell disease begin producing a defective form of hemoglobin called hemoglobin S instead, which form chains that cause red blood cells to change their shape from round to sickle-shaped. [35] These defective red blood cells have a much shorter life span than normal red blood cells (10–20 days compared to up to 120 days). [36]
Student Zoe Davis, 20, was just weeks into her junior year when she landed back in the hospital with severe sickle cell pain earlier this month. She knows new gene therapies may provide long-term ...
Sickle cell disorders, which are the most prevalent form of hemoglobinopathy. Sickle hemoglobin (HbS) is prone to polymerize when deoxygenated, precipitating within the red blood cell. This damages the RBC membrane resulting in its premature destruction and consequent anemia.
CNN staffer Sharon Browne-Peter was diagnosed with sickle cell disease before she was born and needs regular blood transfusions to stay healthy. Ethnically-matched blood offers the best treatment ...
