This is a nice story to point to because it illustrates the active scientific process. An early finding seems to be on stable ground, so the next step is to see if that finding can be supported or corroborated by expanded testing in multiple platforms. This is both the beauty and strength of the discipline.
For this study, Laje and colleagues analyzed DNA samples from 1,915 participants, looking for associations between reports of suicidal ideation at 768 sites in 68 genes.
Statistically, I like the methodology. It's remarkable to note this kind of study probably could not have taken place five years ago, at least in this capacity, the technology is so new.
