UCSC Get Cpg Islands

Get CpG island annotations for a genomic region from UCSC Genome Browser. CpG islands are genomic regions with high CpG dinucleotide density, often found at gene promoters. Methylation of CpG islands is associated with gene silencing. Returns CpG island locations, length, CpG count, GC content, and observed/expected CpG ratio. Use this to identify CpG islands near genes of interest for methylation analysis, or to characterize the regulatory landscape of a genomic region.
