A total of 340 individuals living in seven localities of two Brazilian Indian groups (Macushi and Icana River Indians) were studied with respect to coagulation factor XIIIA subtypes. No inter- or intra-tribal differences were observed. The most striking finding was that FXIII*1A, an allele which is fairly common among Asiatic Mongoloids like the Japanese (27%), was nearly absent in these Indians.
对生活在巴西两个印第安群体（马库希族和伊卡纳河印第安人）七个地区的340人进行了凝血因子XIIIA亚型的研究。未观察到部落间或部落内的差异。最显著的发现是，FXIII*1A等位基因在这些印第安人中几乎不存在，而该等位基因在像日本人这样的亚洲蒙古人种中相当常见（27%）。
