Summaries for LMBRD1 Gene

Entrez Gene Summary for LMBRD1 Gene

  • This gene encodes a lysosomal membrane protein that may be involved in the transport and metabolism of cobalamin. This protein also interacts with the large form of the hepatitis delta antigen and may be required for the nucleocytoplasmic shuttling of the hepatitis delta virus. Mutations in this gene are associated with the vitamin B12 metabolism disorder termed, homocystinuria-megaloblastic anemia complementation type F.[provided by RefSeq, Oct 2009]

GeneCards Summary for LMBRD1 Gene

Disorders for LMBRD1 Gene

(1) OMIM Diseases for LMBRD1 Gene (612625)


  • Methylmalonic aciduria and homocystinuria type cblF (MMAHCF) [MIM:277380]: A disorder of cobalamin metabolism characterized by decreased levels of the coenzymes adenosylcobalamin (AdoCbl) and methylcobalamin (MeCbl). It is due to accumulation of free cobalamin in lysosomes, thus hindering its conversion to cofactors. Clinical features include developmental delay, stomatitis, glossitis, seizures and methylmalonic aciduria responsive to vitamin B12. {ECO:0000269 PubMed:19136951}. Note=The disease is caused by mutations affecting the gene represented in this entry.
