Summaries for AMN Gene

Entrez Gene Summary for AMN Gene

  • The protein encoded by this gene is a type I transmembrane protein. It is thought to modulate bone morphogenetic protein (BMP) receptor function by serving as an accessory or coreceptor, and thus facilitates or hinders BMP binding. It is known that the mouse AMN gene is expressed in the extraembryonic visceral endoderm layer during gastrulation, but it is found to be mutated in amnionless mouse. The encoded protein has sequence similarity to short gastrulation (Sog) and procollagen IIA proteins in Drosophila. [provided by RefSeq, Jul 2008]

Disorders for AMN Gene

(1) OMIM Diseases for AMN Gene (605799)


  • Recessive hereditary megaloblastic anemia 1 (RH-MGA1) [MIM:261100]: 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. Note=The disease is caused by mutations affecting the gene represented in this entry.
