Localization of CpG islands (bars) within the S100 gene cluster on human chromosome 1q21. The CpG Island Searcher and CpGplot programs were used. Only islands fulfilling the following criteria: CG content >55%, expected CpG/observed CpG >0.65, length >200 bp and identified by both programs are shown. Islands longer than 500 bp are indicated by thick bars. Positions of the examined regions are given according to the USCS Genome Browser
