Summaries for TFR2 Gene

Entrez Gene Summary for TFR2 Gene

  • This gene encodes a single-pass type II membrane protein, which is a member of the transferrin receptor-like family. This protein mediates cellular uptake of transferrin-bound iron, and may be involved in iron metabolism, hepatocyte function and erythrocyte differentiation. Mutations in this gene have been associated with hereditary hemochromatosis type III. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, May 2011]

GeneCards Summary for TFR2 Gene

TFR2 (Transferrin Receptor 2) is a Protein Coding gene. Diseases associated with TFR2 include hemochromatosis, type 3 and tfr2-related hereditary hemochromatosis. Among its related pathways are AMPK Enzyme Complex Pathway and Iron metabolism in placenta. GO annotations related to this gene include peptidase activity and transferrin receptor activity. An important paralog of this gene is FOLH1.

Disorders for TFR2 Gene

(1) OMIM Diseases for TFR2 Gene (604720)


  • Hemochromatosis 3 (HFE3) [MIM:604250]: A disorder of iron metabolism characterized by iron overload. Excess iron is deposited in a variety of organs leading to their failure, and resulting in serious illnesses including cirrhosis, hepatomas, diabetes, cardiomyopathy, arthritis, and hypogonadotropic hypogonadism. Severe effects of the disease usually do not appear until after decades of progressive iron loading. {ECO:0000269 PubMed:11313241, ECO:0000269 PubMed:12130528, ECO:0000269 PubMed:14633868}. Note=The disease is caused by mutations affecting the gene represented in this entry.
