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

Sample Information:

Most of the Yoruba individuals in this sample are urban health care workers from Benin City, Nigeria, collected by Prof. Friday E. Okonofua and collaborators; cell lines established by Dr. J.R. Kidd.

Note: In many publications subset H952 of the HGDP panel (with first and second degree relatives excluded from the original set) and subset H971 (only the first degree relatives excluded) was typed and for this population that decreases the sample size from 25 to 22 individuals.
