In a sample of the Polish population numbering 703 subjects, three GPT types were encountered with the following frequencies: GPT1-1 0.265, GPT 2-1 0,509 and GPT 2-20.226. Frequencies of GPT1 and GPT2 genes were 0.519 and 0.481 respectively. Distribution of types in 217 mother-child pairs and in 12 families with 36 children was consistent with the hypothesis that the GPT system is dependent on a pair of codominant alleles and confirms that the GPT 1-1 and GPT 2-2 types are homozygotes, and GPT 2-1 is a heterozygote.
在一个由703名受试者组成的波兰人群样本中，发现了三种GPT类型，其频率如下：GPT1-1为0.265，GPT 2-1为0.509，GPT 2-2为0.226。GPT1和GPT2基因的频率分别为0.519和0.481。217对母婴以及12个家庭中36名儿童的类型分布与GPT系统依赖于一对共显性等位基因的假设一致，并证实GPT 1-1和GPT 2-2类型为纯合子，而GPT 2-1为杂合子。
