Population frequencies of the two patterns of pepsinogen excretion (with and without pepsinogen 5) and family studies indicate that pepsinogen 5 is controlled by a pair of genes, Pg(a) and Pg(b), at a single autosomal locus and that Pg(a) is dominant.
两种胃蛋白酶原排泄模式(有和没有胃蛋白酶原5)的人群频率以及家族研究表明,胃蛋白酶原5由位于单个常染色体位点上的一对基因Pg(a)和Pg(b)控制,且Pg(a)是显性的。
