For 8 of these loci, TMEM131, TCF7, SH3BP2, SUMO3, CPT1B, CD3Z, EIF4E and PLD6 (LOC201164) we found strikingly different distributions of methylation values (percent methylation averaged over multiple contiguous CpGs) in DS compared to normal PBL (Table 1 and Figure 3 and Figure S2). Here, TCF7 is linked to Dravet syndrome.
