Abstract:

Dear Editor.

We read the recent article of Magalhães da Silva et al1 reporting the correlation between biogeographic ancestries, estimated using 30 ancestry informative markers (AIMs), and self-reported skin color in two different Brazilian Northeastern populations (Fortaleza and Salvador, capitals of the states of Ceará and Bahia, respectively). The authors observed that African ancestry is more correlated in the sample from Salvador than in the one from Fortaleza and that the use of different African populations as proxies of the Brazilian’s African ancestors may influence the results.

One unusual point of this study was taking Han Chinese from Beijing (CHB) as pseudo-ancestors for Amerindians as there is no Native American population included in the HapMap Project (http://hapmap.ncbi.nlm.nih.gov/) and, in addition, because CHB population has been shown to have allele frequencies similar to those of Native Amerindians….
