Summaries for Megaloblastic Anemia-1, Finnish Type

About this section
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.

MalaCards based summary: Megaloblastic Anemia-1, Finnish Type, also known as imerslund-grasbeck syndrome, is related to congenital intrinsic factor deficiency and heart disease, and has symptoms including proteinuria, dementia and confusion. An important gene associated with Megaloblastic Anemia-1, Finnish Type is CUBN (Cubilin), and among its related pathways are Defective MTRR causes methylmalonic aciduria and homocystinuria type cblE and Defective AMN causes hereditary megaloblastic anemia 1. The drugs l-methylfolate and folic acid have been mentioned in the context of this disorder. Affiliated tissues include kidney and thyroid.

Disease Ontology:11 A macrocytic anemia that is characterized by inhibition of DNA synthesis during red blood cell production.

NIH Rare Diseases:48 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. Last updated: 1/6/2014

UniProtKB/Swiss-Prot:70 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.
