Landmark Study Identifies New Genetic Cause of Neurodevelopmental Disorders, Bringing Long-Awaited Answers to Families

A seminal study from researchers at the Icahn School of Medicine at Mount Sinai and their collaborators in the United Kingdom, Belgium, Spain, the Netherlands, and Iceland has uncovered a new genetic cause of neurodevelopmental disorders (NDDs). The discovery offers both closure and hope to potentially thousands of families worldwide who have long been searching for answers. The study, published in the April 10 online issue of Nature Genetics [DOI: 10.1038/s41588-025-02159-5], reveals that mutations in a small, previously overlooked non-coding gene called RNU2-2 are responsible for relatively common NDD. Non-coding genes are genes that don't produce proteins but may still play critical roles in regulating cell functions.
