Neuroferritinopathy may also be caused by the insertion of two extra nucleotide bases. The insertion of bases into the L-chain ferritin gene causes the chain to lengthen and alter the sequence of the amino acids found in the gene, also known as a frameshift mutation. [3] These mutations result in decreased iron-binding ability. [1]
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
The ideal is to increase the body's iron deposits, measured as levels of ferritin in serum, with the aim of reaching a ferritin value between 30 and 100 ng/mL. Another clinical study has shown an increase in ferritin levels in those taking iron compared with others receiving a placebo. [11]
Ferritin is found in most tissues as a cytosolic protein, but small amounts are secreted into the serum where it functions as an iron carrier. Plasma ferritin is also an indirect marker of the total amount of iron stored in the body; hence, serum ferritin is used as a diagnostic test for iron-deficiency anemia and iron overload. [4]
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Iron is both necessary to the body and potentially toxic. Controlling iron levels in the body is a critically important part of many aspects of human health and disease. Hematologists have been especially interested in systemic iron metabolism, because iron is essential for red blood cells, where most of the human body's iron is contained.
Hypochromic anemia may be caused by vitamin B6 deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections (e.g. hookworms) or other diseases (i.e. anemia of chronic disease), therapeutic drugs, copper toxicity, and lead poisoning.
Causes include excessive alcohol use (the most common cause of sideroblastic anemia), pyridoxine deficiency (vitamin B 6 is the cofactor in the first step of heme synthesis [8]), lead poisoning [9] and copper deficiency. [10] Excess zinc [11] can indirectly
