Scientists created a new tool called STRIPE that uses advanced genetic testing to read long strands of RNA (the instructions cells use to make proteins). This tool can detect genetic mistakes that cause rare diseases by looking at how genes are actually working in cells, not just finding the mutations themselves. It's designed to be faster, cheaper, and more practical than older methods, which could help doctors diagnose rare genetic diseases that are hard to identify.
WHY IT MATTERSPatients with undiagnosed rare genetic diseases could finally get answers through more accurate genetic testing, since STRIPE can detect disease-causing variants that standard DNA tests might miss.

Scientists created a new AI system called CoNVict that helps doctors figure out which genetic changes are actually causing rare diseases. Copy number variants (CNVs) are sections of DNA that are duplicated or missing, and they can cause genetic disorders, but it's hard to know which ones matter. This new tool uses artificial intelligence to automatically score and rank these genetic changes so doctors can focus on the ones most likely to be causing a patient's symptoms.
WHY IT MATTERSIf your child has unexplained developmental delays or birth defects and genetic testing found copy number variants, this AI tool could help doctors identify which variant is actually responsible for your child's condition, potentially speeding up diagnosis.

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.
