DNA methylation of fibroblasts from Cockayne syndrome and UV-sensitivity syndrome patients [450k]

ABSTRACT: Cockayne syndrome (CS) is a rare genetic disorder caused by mutation of the DNA repair and chromatin remodelling proteins CSA or CSB. Increasing evidences indicate that the progeroid phenotype of CS cannot be solely ascribed to impaired DNA repair, and UV-sensitivity syndrome (UVSS) patients that are also mutated for CSA or CSB do not age prematurely. Epigenetic modifications constitute a hallmark of ageing. We assessed genome-wide DNA methylation (DNAm) at single-nucleotide resolution on fibroblasts derived from CS versus UVSS patients and healthy donors.
