BDNF and Dravet syndrome: As shown it the scatter plot representation of BDNF protein and mRNA expression, although the control and DS groups were clearly separated (Fig. 7C), the correlation between mRNA and protein levels in individual samples was relatively low (Pearson’s correlation coefficients: −0.09 and −0.20 for controls and patients with DS, respectively), indicating a possible dissociation between mRNA and protein levels in post-mortem human samples.
