Summaries for Megaloblastic Anemia 1

Genetics Home Reference : 25 Imerslund-Gräsbeck syndrome is a condition caused by low levels of vitamin B12 (also known as cobalamin). The primary feature of this condition is a blood disorder called megaloblastic anemia. In this form of anemia, which is a disorder characterized by the shortage of red blood cells, the red cells that are present are abnormally large. About half of people with Imerslund-Gräsbeck syndrome also have high levels of protein in their urine (proteinuria). Although proteinuria can be an indication of kidney problems, people with Imerslund-Gräsbeck syndrome appear to have normal kidney function. Imerslund-Gräsbeck syndrome typically begins in infancy or early childhood. The blood abnormality leads to many of the signs and symptoms of the condition, including an inability to grow and gain weight at the expected rate (failure to thrive), pale skin (pallor), excessive tiredness (fatigue), and recurring gastrointestinal or respiratory infections. Other features of Imerslund-Gräsbeck syndrome include mild neurological problems, such as weak muscle tone (hypotonia), numbness or tingling in the hands or feet, movement problems, delayed development, or confusion. Rarely, affected individuals have abnormalities of organs or tissues that make up the urinary tract, such as the bladder or the tubes that carry fluid from the kidneys to the bladder (the ureters).

MalaCards based summary : Megaloblastic Anemia 1, also known as imerslund-grasbeck syndrome, is related to 3-methylglutaconic aciduria, type i and megaloblastic anemia, and has symptoms including athetosis and cerebellar ataxia. An important gene associated with Megaloblastic Anemia 1 is CUBN (Cubilin), and among its related pathways/superpathways are HIV Life Cycle and Metabolism of water-soluble vitamins and cofactors. Affiliated tissues include kidney, skin and thyroid, and related phenotypes are proteinuria and paresthesia

NIH Rare Diseases : 53 Imerslund-Grasbeck syndrome (IGS) is a rare condition characterized by vitamin B12 deficiency, often causing megaloblastic anemia. IGS usually appears in childhood. Other features may include failure to thrive, infections, and neurological damage. Mild proteinuria (with no signs of kidney disease) is present in about half of affected individuals. IGS is caused by mutations in either the CUBN or AMN gene and is inherited in an autosomal recessive manner. Treatment includes life-long vitamin B12 injections, with which affected individuals can stay healthy for decades.

OMIM : 57 Imerslund-Grasbeck syndrome is a form of congenital megaloblastic anemia due to vitamin B12 deficiency caused by a defect in the vitamin B12/intrinsic factor receptor. See also congenital pernicious anemia due to a defect in intrinsic factor (261000). Adult pernicious anemia (170900) is a distinct autoimmune disorder associated with plasma autoantibodies to gastric parietal cells or gastric intrinsic factor. In these cases, there is gastric atrophy and a relatively high frequency of associated thyroiditis and myxedema. (261100)

UniProtKB/Swiss-Prot : 74 Recessive hereditary megaloblastic anemia 1: Due to selective malabsorption of vitamin B12. Defects in vitamin B12 absorption lead to impaired function of thymidine synthase. As a consequence DNA synthesis is interrupted. Rapidly dividing cells involved in erythropoiesis are particularly affected.
