Genetic polymorphism of red cell enzymes glutamate-pyruvate transaminase (GPT) and glyoxalase I (GLO) was investigated in five villages of the Colombian Andes. The GPT1 and GLO1 gene frequencies show a considerable range, but compatible to the range of European populations. In both the systems there is slight excess of observed homozygosity suggesting that the infrastructure of the subpopulations may be influenced by inbreeding.
在哥伦比亚安第斯山脉的五个村庄对红细胞酶谷丙转氨酶（GPT）和乙二醛酶I（GLO）的遗传多态性进行了研究。GPT1和GLO1基因频率显示出相当大的范围，但与欧洲人群的范围相符。在这两个系统中，观察到的纯合子略有过剩，这表明亚群的基础结构可能受到近亲繁殖的影响。
