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.

New data on the vision of South American Indians.

Bulletin of the Pan American Health Organization, 1976
A total of 466 males and 437 females from four Brazilian Indian tribes were tested for color blindness with Ishihara's plates. Defective persons were found in three of the four tribes, but when these and other groups are considered the evidence suggests that the frequency of this trait is lower among Amerindians than among Caucasian populations.
