D-Loop mtDNA deletion as a Unique marker of chibchan Ameridians [resumen]
Carta al editor. Torroni et al. (1993) presented an extensive restriction-site analysis of Native American mtDNAs from 17 widely dis- tributed Na-Dene and Amerindian tribes. For sometime we have been analyzing mtDNA control ...
Direct screening of a mitochindrial DNA deletion valuable for Ameridian evolutionary research [resumen]
A rapid, simple restriction isotyping method is described for the direct screening of a previously characterized Amerindian mitochondrial DNA (mtDNA) marker ;onsisting of a 6-bp "Huetar" deletion. In a sample of 31 maternally ...
Phenylketonuria in Costa Rica: preliminary spectrum of PAH mutations and their associations with highly polymorphic haplotypes
A preliminary evaluation of the molecular basis of phenylketonuria (PKU) in Costa Rica was made by performing mutational analyses in the six PKU families identified to date. These studies revealed the presence of the ...
mtDNA variation in the chibcha ameridian huetar from Costa Rica
The genetic variation in a Chibcha-speaking Amerindian tribe from lower Central America, the Huetar, was analyzed using nucleotide sequences of the hypervariable segments of the mitochondria! DNA (mtDNA) control region, ...
