But pessimism about the potential of human-genome research to yield medical breakthroughs has arisen from unrealistic expectations. Indeed, while “silver bullets” that can cure our most feared diseases have not been found, progress in the area of gene-drug interactions, known as pharmacogenomics, has been extraordinary.
但是对人类基因研究所能带来潜在医学突破的悲观情绪是不切实际的期望造成的。 事实上，尽管人类并没有找到治愈最凶险疾病的“银弹”，但在基因药物作用（也叫基因药理学）领域却已经取得了引人瞩目的进步。
