  • Cited - the variant is cited in a PubMed indexed article.
  • ESP - the human variant was discovered in the Exome Sequencing Project
  • Frequency - allele frequency data is available for the variant and both alleles are seen in at least one population sample.
  • HapMap - the variant was found to be polymorphic in at least one population sample genotyped by the HapMap project.
  • Multiple_observations - the variant was discovered by different labs or in different sample populations.
  • Phenotype_or_Disease - the variant was associated with a known phenotype or disease.
