“DNA underlies almost every aspect of human health, both in function and dysfunction.
Obtaining a detailed picture of how genes and other DNA sequences function together and interact with environmental factors ultimately will lead to the discovery of pathways involved in normal processes and in disease pathogenesis. Such knowledge will have a profound impact on the way disorders are diagnosed, treated, and prevented and will bring about revolutionary changes in clinical and public health practice."

“If it were not for the great variability among individuals medicine might as well be a science and not an art."
-Sir William Osler, 1892
