ALFRED       The ALlele FREquency Database   
ALFRED is a resource of gene frequency data on human populations
supported by the U. S. National Institute of Justice.
ALFRED is designed to make allele frequency data on human population samples readily available for use by the scientific and educational communities.
Current funding for ALFRED ends on December 31st, 2018 with a possible extension of access through March 31, 2019. We are looking at options to transfer this resource, that is widely used internationally, to a group or institution that can maintain the current ‘open access’ format. You may contact Prof. Kenneth Kidd ( or Dr. Haseena Rajeevan ( with suggestions and concerns.
