  • Ban on Genetic Discrimination in Workplace

    Its purpose is to provide equal job opportunities for people with disabilities. The ADA protects people with disabilities from discrimination.
  • Physical Map of Human Genome Completed

    A physical map used sequence-tagged sites as markers to order large segments of DNA. This was a big milestone toward the goal.
  • International Strategy Meeting on Human Genome Sequencing

    The first international strategy meeting on human genome sequencing drew in scientists from countries in Europe, North America, and Asia funding human genome sequencing projects. The scientists gathered to compare sequencing strategies and to discuss guidelines for releasing data. The attendees agreed that all human sequence data they find should be made free and available to the public.
  • Human Gene Map Created

    Scientists created a map showing the locations of ESTs representing fragments of more than 16,000 genes from throughout the whole genome.
  • Human DNA Sequence Begins

    -The National Human Genome Research Institute funded pilot projects to find efficient strategies for complete sequencing of the human genome. The pilot projects tested the feasibility of large-scale sequencing, and also explored how accurate and how costly alternative approaches might be.
  • Recommendations of Genetic Testing

    The Task Force declared that safe and effective genetic tests should not only be valid and useful, but that they should be performed in laboratories of assured quality and used properly by health care providers and consumers. They didn’t recommend specific tests, rather a framework.
  • HGP Map Included 30,000 Human Genes

    HGP researchers released a gene map that included 30,000 human genes, estimated to represent approximately one-third of the total human genes.
  • Genome of Roundworm C. elegans Sequenced

    In December 1998, the first genome sequence of a multicellular organism (the roundworm Caenorhabditis elegans) was completed.
  • Full-scale Human Genome Sequencing

    HGP participants advanced their goal of obtaining draft sequence covering 90 percent of the human genome to 2000.
  • Chromosome 22

    In December 1999, the HGP completed their first finished full-length sequence of a human chromosome, chromosome 22. This accomplishment showed the power of the HGP method of clone-by-clone sequencing.
  • Free Access to Genomic Information

    March 2000 The U.S. President Clinton and U.K. Prime Minister stated that raw, fundamental data about human genome sequence and its variations should be freely available to the public.
  • First Draft of the Human Genome Sequence Released

    The Human Genome Project international consortium published a first draft and initial analysis of their human genome sequence. Researchers can access this data through public databases on the Internet and can use the information without any restriction.
  • Researchers Find Genetic Variation Associated with Prostate Cancer

    Researchers identified a gene on chromosome 1 that is associated with a hereditary form of prostate cancer. The work was a collaboration between the researchers at the National Human Genome Research Institute, Johns Hopkins Medical Institutions, and The Cleveland Clinic.
  • Human Genome Project Completed

    The International Human Genome Sequencing Consortium announced the successful completion of the Human Genome Project more than two years ahead of schedule and under its budget.
  • Fiftieth Anniversary of Watson and Crick's Description of the Double Helix

    The model made by Francis Crick and James Watson resulted from nearly two years of work and was partly based on X-ray diffraction data from colleagues Maurice Wilkins and Rosalind Franklin. Crick, Watson, and Wilkins shared the 1962 Nobel Prize in Physiology or Medicine for their work.
  • The First National DNA Day Celebrated

    The United States Congress passed a resolution setting aside the day April 25th as National DNA Day. The date was chosen to remember the 50th anniversary of the publication of the landmark paper by Francis Crick and James Watson describing the double helix model of DNA.
  • The First National DNA Day Celebrated

    Scientists and staff from the National Human Genome Research Institute visited schools in their own hometowns, giving presentations and speaking with students and teachers about the genomic revolution.
