TL;DR: A highly asymmetric pattern of mating in early Antioquia, involving mostly immigrant men and local native women is indicated, with the frequency of the four Amerind founder lineages being closest to Native Americans currently living in the area.

TL;DR: Interestingly, despite a nearly complete Native American mtDNA background, Antioquia has a markedly predominant European ancestry at the autosomal and X chromosome level, which suggests that, after foundation, continuing admixture with Spanish men (but not with native women) increased the European nuclear ancestry of Antioqia.

TL;DR: Admixture analysis of the Colombian populations suggests an asymmetric pattern of mating involving mostly immigrant men and native women, and the concordance of these estimates does not support an important difference in migration rates between the sexes throughout the history of South Amerinds.

TL;DR: Evaluating the etiologic/modifier role of the short variant of a functional length polymorphism in the promoter region of the serotonin transporter in a case / control sample for bipolar mood disorder collected from an isolated South American population found an excess was seen in younger cases and in cases with psychotic symptoms.

TL;DR: In this article, a comparative analysis of two poblaciones, Aranzazu et al. and Marinilla, was performed, comparing them with Rionegro, a población with caracteristicas similares a Marinilla and its zona de influencia.
