Genetic structure of the population of Matambú, Costa Rica, was investigated using 6 genetic markers: ABO and Rh blood groups, and 4 serum proteins: albumin, ceruloplasmin, haptoglobin and transferrin. All the individuals were Rh+ and the I degrees allele had a high frequency (0.89). There are 4 polymorphic alleles in ceruloplasmin, including a possible new variant (3.8%). Transferrin Dchi had a remarkably high frequency (0.11). These results indicate that this group is of Amerindian origin although there are Caucasic and Negroid genes present. The genetic constitution of Matambú differs from that of the other Amerindian groups such as the Guaymí, from Chibcha stock, which supports the hypothesis of a Mesoamerican origin.
利用6种遗传标记对哥斯达黎加马坦布的人群遗传结构进行了研究：ABO和Rh血型，以及4种血清蛋白：白蛋白、铜蓝蛋白、触珠蛋白和转铁蛋白。所有个体均为Rh阳性，I度等位基因频率较高（0.89）。铜蓝蛋白中有4个多态性等位基因，包括一个可能的新变体（3.8%）。转铁蛋白Dchi的频率非常高（0.11）。这些结果表明，该群体起源于美洲印第安人，尽管存在高加索人和黑人基因。马坦布的遗传构成与其他美洲印第安群体如来自奇布查族的瓜伊米不同，这支持了中美洲起源的假说。
