From: DNA methylation study of fetus genome through a genome-wide analysis
The clone sequencing result of methylation DNA marker located on chromosome 21:38791600–38792000. The DNA Marker is a fetus hypermethylation DNA marker and related with Erythroblastosis virus E26 oncogene onmcogene homolog (ERG) gene.
