In the US, gene therapy research has already been under way for seven years, with government funding to the tune of $ 300 million annually, while the US Department of Health has committed $ 3 billion to the completion, by the year 2003, of a project to determine the position of every gene in the human genome.
美國從七年前就開始從事基因治療研究，政府一年投入約三億美金的研究經費。此外，美國衛生總署還將耗資三十億美金、計畫在二○○三年完成確定每個基因位置所在的「基因定序」工作。
