Blood samples from 340 unrelated individuals in Fukui prefecture in the central part of Japan were tested in order to determine the gene frequencies of the C6 common alleles. The gene frequencies calculated were as follows: C6 A, 0.478, C6 B, 0.464, C6 B2, 0.052 and rare alleles, 0.006. It was demonstrated that C6 phenotyping from blood stains aged over a period of 1 year, could be performed correctly. The quantity of detectable whole blood after this period amounted to less than 2 microliter.
为了确定C6常见等位基因的基因频率，对日本中部福井县340名无亲缘关系个体的血样进行了检测。计算得到的基因频率如下：C6 A，0.478；C6 B，0.464；C6 B2，0.052；稀有等位基因，0.006。结果表明，对于保存超过1年的血痕，能够正确进行C6表型分析。在此之后可检测到的全血量不足2微升。
