The team also discovered an episignature associated with severe ReNU syndrome (in red, compared to controls in purple). This could help to diagnose ReNU syndrome in individuals without genome sequencing 🤞

Additionally, once more, the study of the methylation profile ("episignature") was fundamental for the classification of the variant. Overall, here we suggested that variants impacting exon 20 may be associated to a distinct form of Rubinstein–Taybi syndrome (RSTS).
