The refSNP Summary Report: Allele Summary and Integrated Maps Sections. The Allele Summary section of the refSNP report provides clinical significance (A), where the phenotype may be viewed by clicking on either the VarView or the OMIM buttons; the allele origin (B), indicated as Germline or Somatic for each allele; the Minor Allele frequency (C); Validation Status (D), where definitions for graphic icons indicating validation class are viewed by clicking the “Validation Status" column header link (D); and links to both internal and external resources (E) that provide additional data. The Integrated Maps section of the refSNP report provides a summary of genome mapping information for the variation (F), which can be accessed on the NCBI Sequence Viewer by clicking on any value in the Chromosome Position (Chr Pos) column or the Contig Position (Contig Pos) column. The magnifying glass icon (G) links to a view of the variation in the 1000 Genomes Browser.
