临床上常用的一种通过阻断β受体的抗心力衰竭(简称心衰)药物只对50%的病人有效。基因研究发现,β受体基因多形性与该药物的疗效有关。在人群中,β受体基因有两种常见表型,一种是表达的受体在蛋白结构的特定部位含精氨酸,另一种是含有甘氨酸。每个人从父母那里遗传两套基因,因 Commonly used in clinical practice by blocking beta receptor anti-heart failure (HF) drugs only 50% of patients effective. Genetic research found that, β receptor gene polymorphism and the efficacy of the drug. There are two common phenotypes of the beta receptor gene in the human population, one is that the expressed receptor contains arginine at a specific site of the protein structure and the other contains glycine. Everyone inherits two sets of genes from their parents
