ST6GALNAC6

Chr 9

ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 6

Also known as: SIAT7-F, SIAT7F, ST6GALNACVI

ST6GALNAC6 encodes a sialyltransferase that transfers sialyl groups to glycoproteins and glycolipids with alpha-2,6-linkage specificity, particularly catalyzing ganglioside GD1alpha biosynthesis from GM1b and other complex glycolipid modifications. The gene shows low constraint to loss-of-function variation (pLI 0.002, LOEUF 0.815), and no definitive human disease associations have been established from the provided data.
