Rubinstein-Taybi Syndrome: Functional Imaging and Therapeutic Trial

Summary

An exploratory phase 2 therapeutic trial in children from 6 to 21, RTS carriers, randomized to be treated either with sodium valproate with the usual pediatric dosage (30 mg/kg/j), or by placebo for one year. The investigator would like to include children because they could best profit from it due to their neuronal plasticity as CBP and EP300 take effect through neuronal and synaptic plasticity. The therapeutic effect of sodium valproate in RTS patients will be assessed thanks to a clinical approach (learning and memory neuropsychological evaluation, fine motor skills assessment by pointing), to a biological approach (histone acetylation functional tests), and to imaging (morphological and functional MRI).
