This was the first talk in oral presentations C on Day 2. The Session was title “Epigenomics of Rare Diseases (Symposium for Rare Disease Research UK EpiGenRare MRC Node)”
🗣️ Title of this talk was: “A novel segmental ageing syndrome demonstrates DNA methylation causes multiple age-related pathologies”
The photo depicts Prof Jackson delivering the conclusion of the talk, which states: “DNA hypermethylation causes age-related pathologies”. The slide includes a scatter plot with “DNA methylation age” on the Y axis and “chronological age” on the X axis, showing that CpG methylation changes strongly correlate with chronological ageing.
This conclusion followed the description of a novel segmental ageing syndrome caused by gain-of-function variants in DNMT3A, characterised by a phenotype that mimics aspects of ageing with associated DNA methylation changes.

📖🗣️ The opening slide featured a quote from Arthur Conan Doyle (1892): “It has long been an axiom of mine that the little things are indefinitely the most important”, setting the scene for the story that followed: the discovery of RNU2-2 and RNU5B-1 neurodevelopmental disorders, caused by pathogenic variants in two “small” major spliceosomal RNA genes, collectively termed RNUpathies.

🗣️ Title of this talk was: “Biallelic variants in the non-coding RNA gene RNU4-2 cause a recessive
neurodevelopmental syndrome with distinct white matter changes”
🎆 The slide depicts the conclusions of the talk:
1) An SGE (Saturation Genome Editing) assay highlights a novel autosomal recessive neurodevelopmental syndrome in RNU4-2
2) Cystic white matter changes are a key feature
3) The U4-2:U4-1 ratio is a potential diagnostic biomarker
4) Dominant and recessive disorders in RNU4-2 are genetically, clinically, and molecularly distinct

🗣️ Title of this talk was: “Early initiation of sulphonylurea therapy improves neurodevelopmental outcomes in individuals with KCNJ11-related iDEND syndrome (developmental delay, epilepsy and neonatal diabetes)”
🎆 The slide depicts three “Draw a man” tasks, each performed by individuals with KCNJ11-related iDEND syndrome that received sulphonylurea (SU) therapy at different ages (drawn aged 9, SU in utero; drawn aged 16, SU aged 4; drawn aged 22; SU aged 17) alongside the caption “NVIQ highest (70) in individual also treated with glibenclamide in utero”
