About MMAB

Cytogenetic location: 12q24.11 Genomic coordinates (GRCh38): 12:109,553,715-109,573,504 (from NCBI)

This gene has 10 transcripts (splice variants), 201 orthologues and is associated with 3 phenotypes. Ubiquitous expression in liver (RPKM 6.8), adrenal (RPKM 5.6) and 25 other tissues.

Summary

This gene encodes a protein that catalyzes the final step in the conversion of vitamin B(12) into adenosylcobalamin (AdoCbl), a vitamin B12-containing coenzyme for methylmalonyl-CoA mutase. Mutations in the gene are the cause of vitamin B12-dependent methylmalonic aciduria linked to the cblB complementation group. Alternatively spliced transcript variants have been found.
