TGFB2 and autism: Considering TGFB2, similar to iPSC-derived astrocytes, the target CpGs of site A exhibited DNA hypomethylation in the postmortem brain samples of patients with autism vs. controls (~50%, Mean ± SEM in controls and autism, 1.16 ± 0.27 and 0.4805 ± 0.1, respectively, p = 0.05, Figure 2J).
