Annotation of the multiple biochemical or phenotypic consequences of individual variations in genomic sequence is accomplished through (i) the annotation of a single dbSNP record on the genome sequence to indicate the presence and extent of variation, and (ii) the maintenance of a list of accession links and URLs within the dbSNP record to other information resources. In this way a single variation can be easily represented in multiple biochemical pathways or phenotypic backgrounds.
