Gene-centred search results. By using the gene-centred search approach, a list of the genes for which results were found for the selected disease are presented, sorted in alphabetical order. Two possibilities for browsing the results on these genes are available: "See Variants" and "See References". By clicking the link "See Variants", a page comprising two pieces of information is displayed on the browser: dbSNP-related information for the gene and literature-related information (see Figure 4). By clicking "See References", text passages from all the abstracts found for the sequence variants of the gene are displayed, in a format similar to the one illustrated in Figure 5.
