Sequence and expression analysis of human chromosome 20 gaps

ABSTRACT: The finished human genome-assemblies comprise several hundred un-sequenced euchromatic gaps, which may be rich in long polypurine/polypyrimidine stretches. Human chromosome 20 currently has three remaining un-sequenced gaps on its q-arm. All three gaps are within gene-dense regions, or overlap loci associated with human disorders, including one gap, which is at DLGAP4. In this study we sequenced, determined the complete sizes and assessed epigenetic landscapes of all three un-sequenced gaps on human chromosome 20 using a methodological approach involving Sanger sequencing, mate-pair paired-end high-throughput sequencing and chromatin and methylation analysis. We found histone H3K27me3 to be distributed across all three gaps in immortalized B-lymphocytes. We found five novel CpG islands in
