Esterase D in South American Indians.

American journal of human genetics, 1976
Significant variation in the frequency of Esterase D isoenzymes was found in 1,070 individuals belonging to eight South American Indian tribes. The Es D1 allele shows frequencies varying from .36 to 1. A region of low prevalence of this allele seems to exist in northern Brazil, involving the Parakanan, Gorotire, and Krahó.

Cytochrome P4501A1 polymorphisms in South American Indians.

Human biology, 2001
A total of 131 individuals from five Brazilian Indian tribes were studied for two CYP1A1 gene polymorphisms. The presence of the *val allele at codon 462 varied from 54% in the Surui to 97% in the Xavante, while the presence of the MspI restriction site (*m2 allele) at position T6235C ranged from 72% in the Gavião to 95% in the Xavante.
