The Blood Group Antigen Gene Mutation Database (BGMUT) was set up under the aegis of the Human Genome Variation Society (HGVS) in 1999. It documents variations in genes that directly or indirectly affect our blood groups. It thus is a locus-specific mutation database (LSDB) that covers multiple genes. The database was compiled and has been curated by Olga O. Blumenfeld, PhD, Department of Biochemistry and Santosh K. Patnaik, MD, PhD, Department of Cell Biology, Albert Einstein College of Medicine, New York, NY. In 2006, this website moved to the NCBI to become part of dbRBC. Many who are experts in the study of blood group systems, have contributed to the development of this database by providing, among other things, information on the systems and the alleles.
