Genes affected
ST8SIA6 (HGNC:23317): (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 6) This gene encodes a member of the glycosyltransferase 29 protein family. Members of this protein family synthesize sialylglycoconjugates. Sialylation may contribute to multidrug resistance in cancer cells. Alternative splicing results in multiple transcript variants.
