Genes affected
GFPT1 (HGNC:4241): (glutamine--fructose-6-phosphate transaminase 1) This gene encodes the first and rate-limiting enzyme of the hexosamine pathway and controls the flux of glucose into the hexosamine pathway. The product of this gene catalyzes the formation of glucosamine 6-phosphate. [provided by RefSeq, Sep 2008]
