^aOverrepresented functional terms for genes up- or downregulated (p < 0.01) in FSHD vs. control myoblasts (Mb) or myotubes (Mt) were identified by bioinformatics programs. Details and the names of the dysregulated genes are given in Additional File 8 Table S5.
^bThe number of genes for a given pathway or GO-term that were up- or downregulated in FSHD vs. control myogenic cells/the total number of genes for that pathway or GO-term that were included in the microarray.
