title: Distribution of some erythrocytary enzymes in the Piaroa Indians of Venezuela.
abstract: Eight enzyme gene markers were studied in a sample of Piaroa Indians of Venezuela. ADA, DIA, PGD and AK markers seemed to be non-polymorphic whereas the following markers were found to be polymorphic: ACP1, where the only common electrophoretic alleles present were ACP1*A and ACP1*B (.955); ESD (ESD*1 = .781); PGM1 (PGM1*1 = .736) for which the subtypes (PGM1*1S = .546; PGM1*1F = .190; PGM1*2S = .140; PGM1*2F = .124) were also tested, and GLO1 (GLO1*1 = .347). Some showed a certain heterogeneity in distribution within the Piaroa population. The Piaroa Indians turned out to be different from other ethnic groups living in the same territory.
