Genes affected

ST6GALNAC5 (HGNC:19342): (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 5) The protein encoded by this gene is a Golgi type II transmembrane glycosyltransferase. The encoded protein catalyzes the transfer of sialic acid to cell surface proteins to modulate cell-cell interactions. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]
