Official press release from the research team that published the primary RNU2-2 paper. Quotes lead author Dr. Daniel Greene and senior author Dr. Ernest Turro, and explains how whole-genome sequencing of 50,000+ individuals made the discovery possible.

Accessible summary of the Nature Genetics findings for a general science audience, covering the discovery, prevalence estimates, and implications for the thousands of families worldwide who may receive a diagnosis.

Plain-language summary emphasizing that RNU2-2 mutations typically arise spontaneously (de novo) rather than being inherited, and highlighting how the discovery underscores the importance of previously overlooked non-coding genes in brain development.

Explains what RNU2-2 is — a small non-coding gene that does not produce proteins but plays an essential role in regulating cellular functions — and how this discovery builds on the team's earlier work with RNU4-2/ReNU syndrome.

Features the story of 18-year-old Rose Anderson from Stretford, Manchester — diagnosed with RNU2-2-related disorder in October 2024 after nearly a lifetime of unresolved seizures and developmental delay. A deeply human account of the diagnostic journey and what a diagnosis can mean for a family.

"You wonder if it's just a random thing that has happened or parents sometimes look to themselves for the cause." — Rose's mother, Lyn Anderson

Explains how the National Genomic Research Library — holding data from 100,000 Genomes Project participants — enabled these discoveries. Describes RNU2-2 in the context of the broader "non-coding genome" or "DNA dark matter," and why whole-genome sequencing is essential to find these variants.

Wikipedia's reference article on RNU2-2 syndrome. Describes it as an autosomal dominant disorder (OMIM: developmental and epileptic encephalopathy type 119) caused by de novo variants in RNU2-2, with the most common mutations at n.4G>A and n.35A>G.

The official wire press release distributed to science journalists worldwide at the time of publication in Nature Genetics.

A Washington Post feature profiling families of children with the closely related ReNU (RNU4-2) syndrome, covering the broader landscape of RNU gene disorders including RNU2-2. Five families gathered in a D.C. park to share their stories.

Coverage with commentary from Prof. E. Shyam P. Reddy (Morehouse School of Medicine), explaining that RNU2-2 mutations appear to arise de novo — spontaneously rather than being inherited — making the discovery especially important for families with no prior history of similar conditions. Notes that the mutations disrupt RNA splicing and gene expression during brain development.

In-depth coverage noting that unlike many inherited disorders, RNU2-2 mutations arise de novo and are not passed down from parents. Highlights the discovery of a separate somatic mutation in RNU2-2 that appears to accumulate in healthy individuals with age, raising questions about its potential role in age-related neurological conditions. Also emphasizes the broader significance of whole-genome sequencing in uncovering hidden causes of disease.

A detailed expert blog post by renowned epilepsy geneticist Dr. Ingo Helbig covering the broader class of RNU-related spliceosome disorders, including RNU2-2. Draws comparisons to other epilepsy gene discoveries, explains why these conditions are often missed on traditional exome sequencing, and places RNU2-2 in the context of the rapidly evolving RNU gene discovery landscape.

Spanish-language coverage of the RNU2-2 discovery for families and clinicians in Spain and Latin America — particularly relevant given the involvement of Spanish researchers in the original study.
