Myriad Genetics, Inc. is an American molecular diagnostic company based in Salt Lake City, Utah, United States. Myriad employs a number of proprietary technologies that permit doctors and patients to understand the genetic basis of human disease and the role that genes play in the onset, progression and treatment of disease. This information is used to guide the development of new molecular diagnostic products that assess an individual's risk for developing disease later in life (predictive medicine), identify a patient's likelihood of responding to a particular drug therapy (personalized medicine), assess a patient's risk of disease progression and disease recurrence (personalized medicine), and measure disease activity. Myriad's discovery of the breast cancer gene, BRCA1 was universally acclaimed as a monumental achievement: "There is no more exciting story in medical science." Myriad was the subject of scrutiny after it became involved in a lawsuit over its patenting practices, which led to the landmark Supreme Court decision Association for Molecular Pathology v.
