That query doesn't seem to have an easy answer on Google, so I'm trying to enter it here. A prominent genomicist asserted a ballpark figure of ~30,000 human genomes in the year 2011. Most of that is in the year 2011 itself. Also, in regards to the "$1,000 genome" question, it seems that some labs can get $4,000 dollar human genomes if they buy in bulk (50 at a time). The price point can even go lower apparently, though no number was divulged. This isn't going to be the "retail" price point obviously, but we're probably at most an order of magnitude away from the $1,000 genome as of now. We were also told of the likelihood of the $100 genome, in today's dollars, in 2020.
