Go ahead and get jealous of GTO. After all, we're based in New York City, and that happens to be where Navigenics is launching its personal genomics service next month, according to Steve Murphy at the Gene Sherpa blog. Murphy posts an e-mail he received from the company advertising its "Navigenics Health Compass" service, which "tests for genetic risk markers for 18 actionable common conditions -- cardiac disease, several cancers, Alzheimer’s among them," according to the blog. Check out the official invitation here. GTO hasn't gotten one yet, but you can bet we'll be camped out on a Soho doorstep come April.
