Humans share 99% of their genes but, according to JacobMcCauley, Ph.D., “that one percent can tell us a lot.” The “1%” in genetic studies refers to the miniscule fraction of DNA that differentiates any two individuals but may be the key for understanding disease susceptibility.

This small variation is leading to significant discoveries.
