CurveIQ: The New Science of Genetic Testing for Scoliosis Risk” changes scoliosis from a crooked‑bone mystery into a biological puzzle that can be solved. For centuries, doctors tried to “pull the knot straight” with braces or rods, yet families kept asking why the curve began at all. The answer, the book explains, was hidden in DNA: dozens of tiny “spelling changes” quietly soften collagen, distort hormone signals, or dull balance reflexes long before an X‑ray looks odd.
