Scientists Find New Recessive Neurodevelopmental Disorder Linked to RNU2-2

Researchers discovered a new recessive neurodevelopmental disorder caused by mutations in the non-coding RNU2-2 gene.

The disorder, named ReNU2 syndrome, results from loss of the U2-2 RNA and shows variable symptoms including developmental delays and movement issues.

The team analyzed 110,009 genomes, validated findings with blood tests, and estimates ReNU2 may explain about 10% of recessive genetic neurodevelopmental cases.

The study highlights that non-coding genes can house common disease-causing variants and should be included in genetic searches.
