Learn to use the dbSNP resource, a large and valuable NCBI database that serves both as a repository for genomic variation data (including single nucleotide polymorphisms, microsatellites and small insertion/deletion mutations) and as a computational analysis resource. Learning to mine the dbSNP data will provide the researcher with extensive data and information about variations, evolution, disease and more. Understanding the structure of rs identifiers and ss identifiers will provide important conceptual features of SNP stored records within dbSNP and at other sites that employ dbSNP data. Access points from the dbSNP and the EntrezSNP interface will be explored.

You will learn:

  • how to query the database by SNP attributes, submitter and other information
  • how to understand the contents of the rsID records and ssID records
  • where to find detailed information about individual variations
  • how to accomplish additional search types of the database
