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."
Myriad Avoids Genetic Counseling 'Bottleneck' For BRCA Testing By Helping Docs Do It Themselves
CEO Peter Meldrum said at a conference this week that Myriad's sales force "provides doctors [with] the tools to do counseling" in-house, and as a result, physicians can bill insurers directly for the service.
