Researchers in Canada studied 715 patients with rare diseases who had their entire genome sequenced (a test that reads all of a person's genetic code). The study found that genome sequencing helped doctors in many ways: it confirmed diagnoses in some patients, changed how doctors treated 36% of patients, found new research opportunities, and identified genetic information that relatives should know about. The test also helped doctors avoid unnecessary tests in 88% of cases.
WHY IT MATTERSIf you have an undiagnosed rare disease, this research shows that whole genome sequencing can help your doctor find answers and change your treatment plan — and it may also reveal important genetic information for your family members.
