ALFRED       The ALlele FREquency Database   
ALFRED is a resource of gene frequency data on human populations
supported by the Yale Center for Medical Informatics.
ALFRED is designed to make allele frequency data on human population samples readily available for use by the scientific and educational communities.
We are happy to inform our users that the ALFRED web interface will continue from the same URL after March of 2019. Since the funding that supported ongoing data curation and new data addition and expansion has ended, we will no longer be able to support those functions. Ongoing support for the web-interface and the back-end database will be provided by Yale Center for Medical Informatics (YCMI)
