  • As previously announced on (April 19, 2018), dbSNP Entrez currently only houses human data. In addition, the Entrez and eUtils report formats RS docsum, XML, ASN.1, FASTA, and FLAT format will no longer be available. dbSNP Entrez eUtils will transition to a new single compact eSummary format, the spec and sample data are here. Please contact [email protected] if you have any comments or concerns.
  • We at NCBI (National Center for Biotechnology Information) within NIH, are working on improving our genetic variation resources. We would like to learn more about how you use allele frequency data so that we can better serve your needs. Please provide your input through this short, 3-minute survey.
