PLCH1 and myeloid sarcoma: In contrast, hyper-methylation identified within the TSS1500 of Nescient helix-loop-helix 2 (NHLH2), Phospholipase C eta 1 (PLCH1), Transmembrane protein 132B (TMEM132B), and WD repeat domain 81 (WDR81) correlated with the decrease in mRNA levels of these genes following demyelination in MS hippocampus.
