Table 1 Chromosomal coordinates of regions of FMR1 epigenetic variability in FXS cells. The major regions or FMR1 epigenetic changes identified in FXS PBMCs and fibroblasts (Figs. 1 and 3). Each region is indicated with a unique ID. The functional location (relative to the transcriptional start site (TSS)/untranslated regions (UTR)), chromosome coordinates, and estimated size of the region of perturbation are indicated

From: Reciprocal changes in DNA methylation and hydroxymethylation and a broad repressive epigenetic switch characterize FMR1 transcriptional silencing in fragile X syndrome
