#EpiSignature
A. Santini et al. Rouen 🇫🇷

Epi2Diag building evidence for episignatures in NDD diagnosis.

Episignature performance not uniform. e.g. 👍 Sotos, NIPBL (not other BafOpaththies) but some others less

Retraining classifiers improved several weaker signatures.

Dominant variants in major spliceosome U4 & U5 small nuclear RNA genes cause NDDs through splicing disruption

#RNU4-2 T loop variants (early, severe) differ to Stem III domain variants (milder)

Episignature (147 probes) correlate swith severity

International study led by
@christeldepienne.bsky.social
145 ReNU syndrome individuals- T-loop variants associated with higher phenotypic severity and more 5'splice site disruption (19 cases).

35 cases/45 controls - identify a shared episignature.
