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."
Are 23andMe's Cutbacks a Harbinger of Hard Times for DTC Genomics Firms?
The Mountain View, Calif.-based direct-to-consumer genomics firm has had a round of layoffs that it said were necessary to remain in business in a difficult economic climate. Competing DTC genomics firms have had cutbacks or are proceeding cautiously.
