Summaries for Megaloblastic Anemia-1, Finnish Type

About this section
Genetics Home Reference:23 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 pernicious anemia and 3-methylglutaconic aciduria, type i, and has symptoms including autosomal recessive inheritance, proteinuria and dementia. An important gene associated with Megaloblastic Anemia-1, Finnish Type is CUBN (Cubilin (Intrinsic Factor-Cobalamin Receptor)), and among its related pathways are Metabolism of vitamins and cofactors and Lipoprotein metabolism. Affiliated tissues include kidney and thyroid.

UniProtKB/Swiss-Prot:67 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.
