Sequencing of the polymerase chain reaction amplified exon 2-4 fragment of the human porphobilinogen deaminase gene revealed a G/T polymorphism (I2G and I2T) in intron 2, and a G/A polymorphism (I3G and I3A) in intron 3 of the gene. The frequencies of these alleles are presented.
人胆色素原脱氨酶基因聚合酶链反应扩增的外显子2 - 4片段测序显示，该基因内含子2存在G/T多态性（I2G和I2T），内含子3存在G/A多态性（I3G和I3A）。文中给出了这些等位基因的频率。
