African American Genome Mappers Pledge To Carry On Despite Grant Rejection
Neeraja Sankaran | Mar 5, 1995 | 6 min read
Researchers working on a large-scale plan to develop a linkage map of the genome of African Americans a project similar to the Human Genome Project (HGP)_vow to continue their efforts, despite being rejected for funding by the National Institutes of Health. As they pursue other sources of funding, they say they will carry on with the project in a loosely associated alliance of smaller research efforts at Howard University and other institutions. "It is just too important a project to be dismant

Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
SNPs as Windows on Evolution
Ricki Lewis | Jan 6, 2002 | 7 min read
Single nucleotide polymorphisms--variants in DNA sequences better known as SNPs and pronounced snips--provide a shortcut to comparing genes and genomes within and among species. The need to study SNPs has spawned a number of companies aimed at matching SNP patterns to disease risks. A few other organizations, however, are taking a broader view: mining SNPs for clues to human diversity and evolution. Association studies that correlate SNP patterns to disease risks are straightforward. Clues to

Human Genetics Society Ponders New Age

The presentations and posters at the recent American Society of Human Genetics (ASHG) annual meeting offered up reams of data that pointed to a commanding future of discoveries. But, as the geneticists and students checked in and got their badges, the Sept. 11 terrorist attacks cast an ominous shadow that could not be ignored. ASHG president Huntington F. Willard addressed it head-on: "Let the clearest and loudest message of this week be that at a time when others would take away freedom of thou
Genetic Variation Illuminates Murky Human History
Douglas Steinberg | Jul 23, 2000 | 8 min read
If humans are 99.9 percent genetically identical, as President Bill Clinton is fond of asserting when he extols the Human Genome Project, that 10th-of-a-percent difference has a lot of explaining to do. How does genetic variation determine a person's unique physical traits? Can it predict someone's susceptibility to a disease? Such questions, pertaining to the present or future, are what occupy most human geneticists. A small group, however, studies genetic variation as a clue to the past. Som
