Marker record example. Shown is the individual record for geneGNB1. Underlined text indicates a hypertext link. External database links are present in this example to dbEST (see Table 2 legend for abbreviations), GDB, Sanger, GenBank, UniGene, and RHdb entries for this marker; to perform a BLAST search of the nonredundant (GenBank), EST (EST), and high-throughput genomic sequence (HTGS) collections in GenBank; to search GeneCards, OMIM, and BioHunt for “GNB1”; and to search the Sanger Centre chromosome 1 mapping database Acedb1 for BACs and PACs with the GNB1 primer sequences. The buttons labeled “MAP OF GNB1” and “GNB1 REGION” provide a graphical depiction of the region surrounding GNB1 analogous to Fig. 3 Cand a tabular summary of all markers mapping to this region analogous to Fig. 3 B, respectively. The data category names listed atleft (such as “Expression status”) are hyperlinked to help pages describing the category.
