Synonyms
DNA hypermethylation of CpG island, epigenetic regulation of gene expression via CpG island hypermethylation, hypermethylation of CpG island, negative regulation of gene expression via CpG island hypermethylation, negative regulation of gene expression via chromosomal DNA cytosine methylation, maintenance of DNA methylation

Definition
An epigenetic gene regulation mechanism that negatively regulates gene expression by methylation of cytosine residues in chromosomal CpG islands. CpG islands are genomic regions that contain a high frequency of the CG dinucleotide and are often associated with the transcription start site of genes.
