The refSNP Summary Report: FASTA, Resource Links, Population Diversity and Validation Summary Sections. The FASTA section provides the variation 5’ flanking sequence (A), the allele (B), and the 3’ flanking sequence (C) as provided by the submission record or determined from an asserted position. The NCBI Resource Links section (D) provides links to additional information (if available) from Genbank, a BLAST analysis, UniGene, OMIM, or Structure (not shown). The Population Diversity section (E) provides a table of genotypes and allele frequencies for the variant from different populations and studies. Click on the Genotype Detail link (F) to see a “Genotype and Allele Frequency” report that provides detailed genotype and allele frequency information for each submitted variation of the cluster. The Validation Summary section (G) is the final section of the refSNP summary report, and provides a summary of the validation status for the variation. To see definitions for the icons used in the Validation Status graphical summary, click on the “Validation status” column header link (H).
