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.
