Our knowledge of all areas of science is always evolving. The study of genetics has certainly come a long way since DNA was first studied in the 1950s. Like any other science, our knowledge around genes, their expression, and how they impact health and functionality increases each day. And like with any other science, we practice with what we have, and expand our practice as our knowledge expands. We would never hold back the ability to help a patient just because someone thinks the science “isn’t there yet”!
