Sickle cell anemia is an autosomal recessive genetic condition where the beta-globin protein subunit of hemoglobin is misshapen, which ultimately leads to a sickle-shaped red blood cell, which is prematurely destroyed and can get stuck in small blood vessels. This video discusses the pathophysiology, clinical signs and symptoms, and treatment ...
The most accurate description of sickle cell disease's genetics is recessive gene#Sickle cell anemia (although I would regard sickling as co-dominant, because cells in the heterozygote appear normal under most conditions but sickling occurs with hypoxaemia). Axl 12:17, 21 Jan 2005 (UTC) In view of the lack of response, I have changed the ...
The medical genetics of Jews have been studied to identify and prevent some rare genetic diseases that, while still rare, are more common than average among people of Jewish descent. There are several autosomal recessive genetic disorders that are more common than average in ethnically Jewish populations, particularly Ashkenazi Jews, because of ...
2.36 billion / 33% (2015) [2] 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.
Hematology. Diamond–Blackfan anemia ( DBA) is a congenital erythroid aplasia that usually presents in infancy. [3] DBA causes low red blood cell counts ( anemia ), without substantially affecting the other blood components (the platelets and the white blood cells ), which are usually normal. This is in contrast to Shwachman–Bodian–Diamond ...
Genetics (from Ancient Greek γενετικός genetikos, “genite” and that from γένεσις genesis, “origin” [1] [2] [3] ), a discipline of biology, is the science of heredity and variation in living organisms. [4] Articles (arranged alphabetically) related to genetics include: Contents: Top. 0–9.
In November 2023, the United Kingdom's Medicines and Healthcare products Regulatory Agency (MHRA) became the first in the world to approve the use of the first drug based on CRISPR gene editing, Casgevy, to treat sickle-cell anemia and beta thalassemia.
Hereditary stomatocytosis describes a number of inherited, mostly autosomal dominant human conditions which affect the red blood cell and create the appearance of a slit-like area of central pallor (stomatocyte) among erythrocytes on peripheral blood smear. The erythrocytes' cell membranes may abnormally 'leak' sodium and/or potassium ions ...
