RBMX functional retrocopy safeguards brain development
Retrotransposition has generated thousands of intronless gene copies in mammalian genomes, yet their contribution to brain development and evolution remains largely unexplored. Here we uncover a criti...

While I was taking a holiday last week, 2 super exciting preprints dropped, adding to another posted 6 days prior. These papers describe a remarkable role for *recessive* variants in *RNU2-2* causing developmental and epileptic encephalopathy 🧵 by the amazing

After our study on RNU4-2 and RNU5B-1 published in May (Nava et al, Nature Genetics 2025), I am excited to share our new preprint reporting dominant and recessive variants in RNU2-2 as a frequent cause of developmental and epileptic encephalopathy (DEE). 📄

Systematic analysis of snRNA genes reveals frequent RNU2-2 variants in dominant and recessive developmental and epileptic encephalopathies
Variants in spliceosomal small nuclear RNA (snRNA) genes RNU4-2 (ReNU syndrome), RNU5B-1 , and RNU2-2 have recently been linked to dominant neurodevelopmental disorders (NDDs), revealing a major, prev...

Saturation genome editing of RNU4-2 reveals distinct dominant and recessive neurodevelopmental disorders
Recently, de novo variants in an 18 nucleotide region in the centre of RNU4-2 were shown to cause ReNU syndrome, a syndromic neurodevelopmental disorder (NDD) that is predicted to affect tens of thous...

I learned some stuff about Bluesky I did not know by reading this. Maybe worth passing it on to others so we can all start getting the full benefit of the 🦋.

I couldn't spot a starter pack for rare disease / clinical genomics, so I started one:
go.bsky.app/SUWZ9Hw
Very much a work in progress, and biased by who I have already found here, so please suggest people to add! Self-nominations encouraged.
