Human Genetic Variation Alters Anthrax Toxin Sensitivity
Martchenko, Candille et al., PNAS
Researchers at Stanford University School of Medicine show that genetic variation affecting capillary morphogenesis gene 2, or CMG2, dramatically alters toxin sensitivity in humans. In its analysis, the team reports on "a CMG2 single-nucleotide polymorphism occurring frequently in African and European populations [that they found] independently altered toxin uptake." The group goes on to suggest "testing of genomically characterized human cell populations may offer a broadly useful strategy for elucidating effects of genetic variation on infectious disease susceptibility."
Ion Torrent Systems Presents $50,000 Electronic Sequencer at AGBT
The instrument will cost less than $50,000 and generate "hundreds of millions of bases" and "millions" of highly accurate reads per run, each several hundred bases in length, according to Jonathan Rothberg, the company's co-founder and CEO. Each run will take about an hour and cost less than $500.
