The ALlele FREquency Database    A resource of gene frequency data on human populations supported by the Yale Center for Medical Informatics.

News:
2016 - Microhaplotype: Microhaplotype data added. Use 'microhap' or 'microhaplotype' in keyword search function to list the microhaplotypes. More information coming soon.

Follow the link 'ALFRED FAQ' to view revised ALFRED FAQ page. Recent Frequency Uploads: We have not been able to catch up with the different download and frequency display formats for some of the recent frequency uploads. Please bear with us while we systematically create these files. SNP Sets: To view SNP sets and related information go to Search-> SNP Sets. Download format for Arlequin: Allele frequency tables available in Arlequin format from individual polymorphism description pages. Creating URLs to description pages: Visit 'Documentation'->'AboutALFRED' ) to learn how to create URLs to ALFRED description pages. Wiki for ALFRED Populations: Interested in annotating ALFRED populations? Visit ALFRED Wiki   and follow the instructions.   2009 - Map Interface Update: Now view allele frequency pie-charts on Google Map. For example here is the google map view of allele frequency pie-charts for rs1159918.    Fst and Avg Heterozygosity available at Summaries->Fst and Avg Het and 'Polymorphism Information' page.   ("Now Sortable"). Mapping Tables: Two new downloadable files mapping ALFRED UID and Entrez Gene Id ( ALFREDGeneInfo.csv ) and ALFRED UID and dbSNP rsnumber ( ALFREDVariantInfo.csv ) can be obtained from 'Summaries'->'Downloads'.
