    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 ...

    CRISPR gene editing (CRISPR, pronounced / ˈkrɪspər / "crisper", refers to " c lustered r egularly i nterspaced s hort p alindromic r epeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.

    Anemia or anaemia (British English) is a blood disorder in which the blood has a reduced ability to carry oxygen. This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.

    For example, sickle-cell anemia is a human genetic disease that results from a single base difference within the coding region for the β-globin section of hemoglobin, causing a single amino acid change that changes hemoglobin's physical properties. [78]

    However, the overall contribution of vitamin B 12 deficiency to the global incidence of anemia may not be significant, except in elderly individuals, vegetarians, cases of malabsorption and some genetic disorders. [87] Anemia is defined as a condition in which there are not enough red blood cells, as the tissues and organs of the body do not ...
