The pathways on WikiPathways are linked to relevant information about the entities present. By clicking on an entity (in this case methionine), the right panel (backpage) appears with aggregated information and links to external databases. In this way, the pathways can provide access to information on genetic variation in dbSNP which will be extended with information from the genetic variation portal
