Genes affected
ST8SIA5 (HGNC:17827): (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 5) The protein encoded by this gene is a type II membrane protein that may be present in the Golgi apparatus. The encoded protein, which is a member of glycosyltransferase family 29, may be involved in the synthesis of gangliosides GD1c, GT1a, GQ1b, and GT3 from GD1a, GT1b, GM1b, and GD3, respectively.
