This analysis revealed cell type-specific methylation levels, but we found no evidence for differences in methylation of TMEM131, SH3BP2, EIF4E, or TCF7 between these 2 cell populations with a direction and magnitude that could account for the altered methylation observed in DS, even if cell numbers were altered (Figure 2A and Figure S4). The gene discussed is TCF7; the disease is Dravet syndrome.
