Abstract

Understanding of the human genome and its functional significance has increased exponentially since the completion of the Human Genome Project in 2003. The HGP fueled the discovery of more than 1,800 disease genes and paved the way for researchers to identify and test for genes suspected of causing inherited diseases. Currently, there are more than 1000 genetic tests for human diseases and conditions on the market. These tests can play an integral role in the delivery of health care by providing information that could potentially form the basis for profound life decisions, such as whether to undergo a prophylactic mastectomy, whether to terminate a pregnancy, or whether to take a particular drug or medication dose.
