Human granulocytic anaplasmosis (HGA) is a tick-borne, infectious disease caused by Anaplasma phagocytophilum, an obligate intracellular bacterium that is typically transmitted to humans by ticks of the Ixodes ricinus species complex, including Ixodes scapularis and Ixodes pacificus in North America.
Global distribution of red blood cell abnormalities. Hemoglobin is a protein that transports oxygen in the blood. Genetic differences lead to structural variants in the hemoglobin protein structure. Some variants can cause disease while others have little to no effect.
A normocytic anemia is an anemia with a mean corpuscular volume (MCV) of 80–100. Paroxysmal nocturnal hemoglobinuria: D59.5: 9688: Paroxysmal nocturnal hemoglobinuria (also known as Marchiafava-Micheli syndrome) is a rare, acquired, life-threatening blood disease, with anemia due to red blood cell destruction, red urine, and thrombosis.
Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are generally single-gene disorders and, in most cases, they are inherited as autosomal recessive traits. [2] [3]
(According to the Cleveland Clinic, microcytic anemia happens when a person’s red blood cells are smaller than usual, which leads to the body not being able to carry as much oxygen.) The E!
This disorder is the most common autosomal recessive disorder in some countries. [6] Hemoglobin A2 is employed to diagnose thalassemia disorders, encompassing both beta and alpha types. In beta-thalassemia, affected individuals express elevated HbA2 levels, which can be a potential indicator of the heterozygous gene marker for the disorder.
The human alpha globin gene cluster is located on chromosome 16 and spans about 30 kb, including seven alpha like globin genes and pseudogenes: 5'- HBZ - HBZP1 - HBM - HBAP1 - HBA2 - HBA1 - HBQ1-3'. The HBA2 (α 2) and HBA1 (α 1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but ...
Due to the fact that Hb H disease does not commonly present with severe anemia, all patients do not require treatment or intervention. Some patients may require folic acid supplementation due to the increased turnover of red blood cells. In cases of hemolytic crisis, patients are treated with a blood transfusion and treatment of the underlying ...
