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.

Researchers in Italy tested a new way to diagnose rare genetic diseases in children using whole genome sequencing—a test that reads all of a person's genetic code. Between 2018 and 2022, they studied 64 children with complex neurological problems that doctors couldn't figure out. This study shows whether this genetic test could help find answers faster for kids with mysterious rare diseases.
WHY IT MATTERSIf your child has unexplained neurological symptoms and multiple doctors haven't found a diagnosis, this research demonstrates that whole genome sequencing through healthcare systems may finally provide answers—potentially ending years of diagnostic uncertainty.

Researchers tested whether people could get genetic testing (genome sequencing) without always needing to see a genetics specialist first. They studied 313 people of all ages who had unexplained symptoms and could refer themselves or be referred by any doctor. The study found that people who referred themselves were just as likely to get a diagnosis as those referred by specialists. This suggests a new way to make genetic testing available to more people while still having genetics experts review the results.
WHY IT MATTERSIf this hybrid model works, patients with rare diseases could access genome sequencing faster and more easily without waiting for a genetics specialist appointment, potentially shortening the diagnostic odyssey that many rare disease patients experience.

Researchers studied how getting a genetic diagnosis through whole genome sequencing (a test that reads all of a person's genes) affects how much healthcare seriously ill children need over time. They looked at medical records from children in the UK between 2016 and 2020 to see if knowing the genetic cause of their illness changed how often they visited doctors, went to the hospital, or needed other medical care.
WHY IT MATTERSIf you have a seriously ill child undergoing genetic testing, this research will help show whether getting a diagnosis actually changes how your child's care is managed and how often you'll need medical visits going forward.
