For the past few days I've been avidly following Daniel MacArthur's tweets from the Personal Genome Conference at Cold Spring Harbor(@dgmacarthur #cshlpg).

The Personal Genomics tweets aren't just interesting because of the science, they're interesting because MacArthur and others have started to take on the conventional dogma in genetic ethics.

For years, there has been a strong message from the clinical genetics and genetics education community that genetic information is dangerous.

Too cold to sleep, I picked up my copy of Masha Gessen's " ... Read more

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. You may be wondering, and rightly so: just what is a SNP?

Never fear, hopefully this post will answer some of those questions.

SNP stands for Single Nucleotide Polymorphism. That's a mouthful. It means some people, will have one base at a certain position, in a sequence of bases, and other people will have a different base at that position. The two forms of SNP are called "alleles." (Usually there are two forms, but that's ... Read more
