Sickle cell disease ( SCD ), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to a rigid, sickle -like shape under ...
Hematology. Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous ), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous ). Those who are heterozygous for the sickle cell allele produce ...
Mendelian traits in humans. 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.

(Reuters) -The U.S. Food and Drug Administration (FDA) on Friday approved two gene therapies for sickle cell disease, making one of them the first treatment in the United States based on the Nobel ...
The two gene therapies are the first approved in the U.S. for sickle cell disease. The FDA has previously OK’d 15 gene therapies for other conditions. In the U.S., an estimated 100,000 people ...
The FDA is expected to decide on the second gene therapy for sickle cell, made by Bluebird Bio, before the end of the year. Bluebird's treatment works differently. It aims to add functional copies ...
The manufacturer Bluebird bio charges $2.8 million in the United States for its one-time treatment Zynteglo (betibeglogene autotemcel). Gene editing therapies aimed at increasing fetal hemoglobin production in beta thalassemia as well as sickle cell anemia by inhibiting the BCL11A gene are also being explored. Surgical

Sickle cell – The gene for HbS associated with sickle-cell is today distributed widely throughout sub-Saharan Africa, the Middle East, and parts of the Indian subcontinent, where carrier frequencies range from 5–40% or more of the population.
The price tags for the two sickle cell therapies in the U.S. are $3.1 million and $2.2 million although the cost for gene therapies can vary by country. The process of giving the therapies is just ...
