Genes affected

GCNT3 (HGNC:4205): (glucosaminyl (N-acetyl) transferase 3, mucin type) This gene encodes a member of the N-acetylglucosaminyltransferase family. The encoded protein is a beta-6-N-acetylglucosamine-transferase that catalyzes the formation of core 2 and core 4 O-glycans on mucin-type glycoproteins.[provided by RefSeq, Apr 2009]
