Summaries for ST6GALNAC2 Gene

Entrez Gene Summary for ST6GALNAC2 Gene

  • ST6GALNAC2 belongs to a family of sialyltransferases that add sialic acids to the nonreducing ends of glycoconjugates. At the cell surface, these modifications have roles in cell-cell and cell-substrate interactions, bacterial adhesion, and protein targeting (Samyn-Petit et al., 2000 [PubMed 10742600]).[supplied by OMIM, Mar 2008]

GeneCards Summary for ST6GALNAC2 Gene

    • Aberrant O-galactosylation of IgA1 molecules plays a role in the development and progression of IgA nephropathy (IgAN). Genetic interactions of C1GALT1 and ST6GALNAC2 variants influence IgA1 O-glycosylation, disease predisposition, and disease severity, and may contribute to the polygenic nature of IgAN.
