Amniotic fluid cells chromatin accessibility in Turner's syndrome

Turner syndrome is a relatively rare condition that is usually associated with the loss of all or part of an X chromosome. Amniotic fluid is a complicated biological material, could contribute to the understanding of turner syndrome pathogenesis. In this study, ATAC-seq analysis of Turner syndrome (45X) and Female (46XX) amniotic fluid cells was applied to illustrate that genome wide chromatin accessible landscapes. Our results show that Turner Syndrome has higher chromatin accessibility than Female on autosomes and has lower chromosome accessibility on the X chromosome. We identified candidate genomic regions and transcript factors that may play an important role in Turner syndrome pathogenesis. Our analysis suggests that the phenotype of Turner Syndrome should be the result of abnormal regulation of gene expression in the whole genome, not just the result of insufficient doses of X chromosome haploids.
