Lookie here -- they've sequenced Craig Venter's genome. What did they learn about Craig? Well, he's European. He has 46 chromosomes. He's got some structural differences from the reference genome. Venter also differs from the reference genome by insertions and deletions.Like every other human, he's got a boat load of repetitive sequences in his genome. And he differs from that reference genome in coding sequences.

Last year, Craig Venter became the first single person to have his genome sequence published (doi:10.1371/journal.pbio.0050254). That genome was sequenced using the old-school Sanger technique. It marked the second time the complete human genome had been published (which led to some discussion as…
"Come quickly, Watson," said Sherlock Holmes, "I've been asked to review a mysterious sequence, whose importance I'm only now beginning to comprehend."
The unidentified stranger handed Holmes a piece of paper inscribed with symbols and said it was a map of unparalleled value.

If you've read any of the many stories lately about Craig Venter or Jim Watson's genome, you've probably seen a "SNP" appear somewhere. (If you haven't read any of the stories, CNN has one here, and my fellow bloggers have posted several here, here, here, here, here, and here.)

The world of genomics is changing. It was initially about sequencing the genome a single representative individual from a particular species. Now, there's a large focus on polymorphism -- that is, sequencing multiple individuals from a single species to study the genomic variation in that species.…
I would have thought that a top candidate for a personal genome sequence should be Linnaeus, I would be interested to know how the genome of our species' type specimen compares to the reference sequence.
Unfortunately, Linnaeus didn't make plans to preserve his body as a taxonomic specimen -- instead it just rotted in Uppsala Cathedral.
However, there are procedures to reestablish type specimens when the original is lost...
Oops, sorry, for some reason I assumed that it had been preserved, it seems like that should be a standard criteria when designating a type...
Shouldn't that be "Craig Venter, Decoded"?
Ugh. I read the Nick Wade story about this in the NYTimes. Not to beat a dead horse, he keeps using the word decode/decoded when sequence/sequenced should be used.
This paper was a real disappointment - disappointing because, as I blogged about here: http://genefinding.blogspot.com - there isn't any new science in this paper. PLoS Biology is trying to establish itself as a competitor to Nature and Science, and if they want to be taken seriously, they shouldn't let themselves be used for a publicity stunt like this. What all the press fails to acknowledge is that Venter's genome was already published - it was the basis for the genome sequence published in Science in 2001 by the team led by Venter (I should know - I was on it). So both PLoS and the press are conveniently forgetting that so they can claim this is something "new." Nonsense.
This is confusing - I had assumed that the reference genome was Venter's. Perhaps he has a particularly unstable genome.
