The positions of density peaks along the entire Chr6. At the UCSC genome browser, one could examine the peak positions with respect to genes, in the context of clinical variants, and Genome-wide Association Studies (GWAS). These tracks facilitate examining the potential imprinted genes in the context of diseases, genetic abnormalities, and genome-wide variants associated with a trait. Note that within nearly 172 Mb DNA, clearly discernable is a very robust peak corresponding to the ICR of ZAC1. Along the chromosome are additional robust peaks for candidate ICRs
