This research article explores how mutations in RNU4-2, a non-coding RNA gene, lead to different neurodevelopmental conditions. Using a technique called saturation genome editing (SGE), the scientists tested every possible genetic variation within the gene to see how each affects cell health. Their findings revealed that mutations in the central critical region cause the dominant ReNU syndrome, where even a single faulty copy of the gene creates severe symptoms. Conversely, the study identified a newly discovered recessive disorder caused by having two faulty copies of the gene in areas…
