DLG2 and neuroblastoma: Methylation array data showed that there was very low methylation of the DLG2 promoter region, no observable difference in the promoter region methylation pattern was observed in 11q-deleted NB compared to 11q normal in NB methylation dataset 1 (GSE73515) (Fig. 4c) and also no DLG2 promoter methylation in general in NB methylation dataset 2 (GSE120650) (Fig. 4d).
