Genes affected

ST6GALNAC6 (HGNC:23364): (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 6) ST6GALNAC6 belongs to a family of sialyltransferases that modify proteins and ceramides on the cell surface to alter cell-cell or cell-extracellular matrix interactions (Tsuchida et al., 2003 [PubMed 12668675]).[supplied by OMIM, Mar 2008]
