Decode Genetics is joining Navigenics and 23andMe in the genomic testing fray, reports the New York Times. Their new service, called deCODEme, will take a cheek swab and $985 to assess someone's disease risk, ancestry, and physiology by using SNP chips. "If people can go into this testing knowing what its limits are, and can take it with a grain of salt, that’s fine," the incoming president of the National Society of Genetic Counselors told the Times, though she warns, "But you have to be really careful about what you know and don’t know."
