  • Title: D1S80 locus variability in three Brazilian ethnic groups.
    Author: Heidrich EM, Hutz MH, Salzano FM, Coimbra CE, Santos RV.
    Journal: Hum Biol; 1995 Apr; 67(2):311-9. PubMed ID: 7729831.
    Abstract:
    We have studied the hypervariable locus D1S80 in 75 white and 53 black Brazilians from Porto Alegre, a southern Brazilian population, and in 50 Brazilian Indians from the Xavante and Zoró tribes. Allele frequencies were significantly different among the three ethnic groups, mainly because of the higher frequencies of alleles *21, *22, *28, and *34 and the lower frequency of allele *18 in individuals of African ancestry and the higher frequencies of alleles *18 and *30 in Brazilian Indians. In the Indian group a restriction in the number of alleles (7) and genotypes (15) was found. The data suggest that the D1S80 locus is a useful interpopulation marker. This is the first report of its allele frequencies in Amerindians.
