Chromosomal breakage in leukocytes of South American Indians

Cytogenetic and Genome Research, 1973
Cytogenetic studies were performed in 1969, 1970, and 1971 on the Yanomama and Piaroa Indians of Venezuela. The early studies involved 49 Yanomama, of whom 13 had 23 cells with extensive chromosome breakage and rearrangement, so-called complex cells. The virtual disappearance of these complex cells in subsequent studies of the Yanomama was accompanied ...

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.
