Genes affected

GBGT1 (HGNC:20460): (globoside alpha-1,3-N-acetylgalactosaminyltransferase 1 (FORS blood group)) This gene encodes a glycosyltransferase that plays a role in the synthesis of Forssman glycolipid (FG), a member of the globoseries glycolipid family. Glycolipids such as FG form attachment sites for the binding of pathogens to cells; expression of this protein may determine host tropism to microorganisms. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]
