Number of discovered genes with known disease-causing mutations 2003 and 2015

The data shows a comparison of the number of discovered genes with known phenotypes or disease-causing mutations in 2003 and 2015. In 2003 only 1,474 genes were identified that had mutations that cause disease, while in 2015, 2,937 genes had been identified with mutations that cause diseases. Since the completion of the human genome project in 2003, gene identification technology has advanced and more phenotypes and disease-causing mutations have been found.
