About 50 scientists from countries publicly supporting large-scale human genome sequencing attended an international meeting in Bermuda on February 25-28, 1996. The meeting was designed to coordinate, compare, and evaluate human genome mapping and sequencing strategies; consider the potential role of new technologies in sequencing and informatics; and discuss scenarios for data release. Attendees included representatives from and scientists funded by The Wellcome Trust, U.K. Medical Research Council, Généthon, NIH National Center for Human Genome Research, DOE, German Human Genome Programme, European Commission, Human Genome Organisation (HUGO), and the Human Genome Projects of France and Japan.
Sessions were held on sequencing strategies and resources; issues related to large-scale, high-throughput sequencing; informatics; and international data dissemination. Almost every major sequencing center in the world was represented, and initial discussions focused on sequencing strategies used by each laboratory. Most groups reported pursuing highly redundant shotgun strategies followed by directed closure, although some discussed the merits of an approach in which sequencing of any region would be done initially using one-pass or low-pass sequencing. Considerable discussion led to the consensus that the final product representing the first human genome sequence should be done at high accuracy.
Only a few human chromosomes (16, 19, 21, 22, and X) clearly have enough sequence-ready clones to initiate immediate sequencing, and only partial maps are available for some of these. Thus many major groups felt that building sequence-ready maps and clones must be integrated with plans for large-scale sequencing. In many cases this would involve converting low-resolution YAC maps to sequenceable clones such as BACs, PACs, or cosmids. For chromosomes without clonal coverage, BAC maps could be generated. Both the mapped BAC and cosmid substrates were considered suitable starting points for large-scale sequencing. Attendees developed a folder of each laboratory's resources available for contribution to the public domain.
The informatics session revealed that a variety of software tools provide alternatives to commercially available packages for sequence-data assembly and analysis. These programs, which offer substantial advantages over previous packages, generally are available free to universities and nonprofit institutes via ftp servers. Many investigators are using the new programs Phred and Phrap by Phil Green (University of Washington, Seattle), which have greatly improved accuracy and editing capabilities.
The following principles were endorsed unanimously by the attendees.
Attendees agreed that meetings of this type should be held annually to discuss new technologies and data dissemination in coordinating human genome sequencing worldwide.
A final poll was conducted at the end of the meeting to determine the sequencing targets and goals of each laboratory. If funding requested from granting agencies is forthcoming, the projected total of human sequence over the next 3 to 5 years would be about 1 billion bases or one-third the human genome. This goal depends on substantial technology improvements and cost reductions. Some laboratory representatives also indicated that they would sequence targeted regions simultaneously in human and mouse genomes.

The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome. See Timeline for more HGP history.
Published from 1989 until 2002, this newsletter facilitated HGP communication, helped prevent duplication of research effort, and informed persons interested in genome research.
