Cause of major subtype of glaucoma discovered

In a paper published in the journal Science, scientists from deCODE genetics and academic colleagues from the National University Hospital in Reykjavik and Uppsala University in Sweden report the discovery of two common single letter variations (SNPs) in the sequence of the human genome that appear to account for virtually all cases of a major subtype of glaucoma.
