Systematic analysis of snRNA genes reveals frequent RNU2-2 variants in dominant and recessive developmental and epileptic encephalopathies.
Non-coding gene mutations emerge as an overlooked but frequent cause of severe childhood epilepsy, expanding where researchers should look for genetic diagnoses.
This third concurrent Nature Genetics paper provides a systematic analysis of all snRNA genes, confirming RNU2-2 as a frequently mutated gene in both dominant and recessive developmental and epileptic encephalopathies. The work establishes non-coding snRNA variants as an underappreciated and common cause of severe neurological disease.
