Data Science Tools Will Speed Rare Disease Solutions

More than 10,000 rare diseases affect up to 400 million people worldwide, and those with rare diseases struggle for about six years on average before they receive an accurate diagnosis. But data-driven innovations are unlocking answers about rare diseases—as well as more common diseases—faster than ever before.
