Sample Description: This sample is part of the Human Genome Diversity Cell Line Panel collected by the Human Genome Diversity Project (HGDP) and the Foundation Jean Dausset (CEPH).

This sample is comprised of Biaka, living in the village of Bagandu, in the southwest corner of the Central African Republic (3.42N; 18E altitude approximately 500m). This group is probably an admixture of 3/4 "non-pygmy" African ancestry and 1/4 Mbuti ancestry. The transformed cell lines were established by Judith R. Kidd. The sources of this sample are L. Cavalli-Sforza (Stanford University) and K.K. Kidd, J.R. Kidd (Yale University).

This sample is known as dataset "H1048" and is a subset of SA001465Q.

Note: In many publications subset H952 of the HGDP panel (with first and second degree relatives excluded ) was typed and for this population that decreases the sample size from 32 to 23 individuals. Studies that typed subset "H971" of the HGDP panel with only the first degree relatives excluded the sample size decreases from 32 to 27.
