Table 1. Correlation of the FXN gene expression level and the shorter allele repeat expansion length with the methylation level of DOWN-GAA region non-CpG sites and adjacent CpG sites in patients with FRDA
Note: # — Spearman's rank correlation coefficient (r); * — р < 0.05; «–» — no correlation; mC — methylated cytosine.
Table 2. Correlation of the FXN gene level expression and the methylation level of sites in all studied regions in a combined cohort adjusted for the group
Note: * — р < 0.05.
