Assume some "toxic" event causes the deletion of a gene. Does anything else happen? New research suggests that deletion of gene #1 is likely to cause a second, "paired" change in gene # 2. Often, but not always, the paired change appears in the same spot in gene # 2. So says a new research paper published in Molecular Cell to summarize research across thousands of strains of yeast cells that are proven as good (not perfect) starting points for understanding happenings in human biosystems. .
A take away for lawyers? Concrete identification of paired genetic changes could take researchers further down the path of fingerprinting the source of a disease.
