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 Defends Policy of Urging Docs to Genetically Counsel BRACAnalysis Customers
Responding to an HHS committee's request for comment on its educational and marketing practices, Myriad maintained that urging doctors to conduct genetic counseling in house instead of referring patients to a genetic counselor is legally sound, follows professional medical societies' standards, and accommodates the shortage of cancer genetics professionals.
