 The main output of the HGP is usually seen as ‘the’ human genome sequence. The draft human genome sequence (about 90% complete) was announced in June 2000, followed in 2001 by the publication of the draft sequences produced by the HGP (International Human Genome Sequencing Consortium 2001) and the privately funded initiative (Venter et al. 2001). The complete (or almost complete (99%)) sequence of the human genome was released in 2003, which also marked the official ending of the HGP (International Human Genome Sequencing Consortium 2004).
