For ten days this month Navigenics will sell their Health Compass service on the streets of Manhattan. For as little as $2500 you can learn about your genetic predisposition for such diverse conditions as Restless Legs Syndrome, Psoriasis and Glaucoma, to name a few. What sets Navigenics apart from DeCode and 23andMe is that, according to them, they focus on conditions “you can take action after learning your results”. Also, Navigenics provides personalized counseling, in which an actual genetic counselor will go over your results with you. So if you hear the sound of someone spitting in SoHo, it may be someone curious about their odds of developing lupus, or maybe not.
