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."
Sequencing Genes Implicated in GWAS Uncovers Rare Variants in Disease Cohort
The researchers identified an accumulation of rare variants in four genes identified by GWAS. They now plan to sequence more candidate genes using Sanger sequencing and, eventually, next-generation sequencing.
