We report a comparative analysis of TS vs. KS regarding differences at the genomic network level measured in primary samples by analyzing gene expression, DNA methylation, and chromatin conformation. X-chromosome inactivation (XCI) silences transcription from one X chromosome in female mammals, on which most genes are inactive, and some genes escape from XCI. In TS, almost all differentially expressed escape genes are down-regulated but most differentially expressed inactive genes are up-regulated. In KS, differentially expressed escape genes are up-regulated while the majority of inactive genes appear unchanged. Interestingly, 94 differentially expressed genes (DEGs) overlapped between TS and female and KS and male comparisons; and these almost uniformly display expression changes into opposite directions. DEGs on the X chromosome and the autosomes are coexpressed in both syndromes, indicating that there are molecular ripple effects of the changes in X chromosome dosage. Six potential candidate genes (\n                    <jats:italic>RPS4X<\/jats:italic>\n                    ,\n                    <jats:italic>SEPT6<\/jats:italic>\n                    ,\n                    <jats:italic>NKRF<\/jats:italic>\n                    ,\n                    <jats:italic>CX0rf57<\/jats:italic>\n                    ,\n                    <jats:italic>NAA10<\/jats:italic>\n                    , and\n                    <jats:italic>FLNA<\/jats:italic>\n                    ) for KS are identified on Xq, as well as candidate central genes on Xp for TS. Only promoters of inactive genes are differentially methylated in both syndromes while escape gene promoters remain unchanged. The intrachromosomal contact map of the X chromosome in TS exhibits the structure of an active X chromosome. The discovery of shared DEGs indicates the existence of common molecular mechanisms for gene regulation in TS and KS that transmit the gene dosage changes to the transcriptome.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1910003117","type":"journal-article","created":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T18:15:21Z","timestamp":1582049721000},"page":"4864-4873","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":94,"title":["Integrated functional genomic analyses of Klinefelter and Turner syndromes reveal global network effects of altered X chromosome dosage"],"prefix":"10.1073","volume":"117","author":[{"given":"Xianglong","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"},{"name":"Department of Genetics, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shining","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Statistics, Stanford University, Stanford, CA 94305;"},{"name":"Department of Biomedical Data Science, Stanford University, Stanford, CA 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Ward","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"},{"name":"Department of Genetics, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"},{"name":"Department of Genetics, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reenal","family":"Pattni","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"},{"name":"Department of Genetics, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhana","family":"Duren","sequence":"additional","affiliation":[{"name":"Department of Statistics, Stanford University, Stanford, CA 94305;"},{"name":"Department of Biomedical Data Science, Stanford University, Stanford, CA 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atanas","family":"Stankov","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Bade Shrestha","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim","family":"Hallmayer","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wing Hung","family":"Wong","sequence":"additional","affiliation":[{"name":"Department of Statistics, Stanford University, Stanford, CA 94305;"},{"name":"Department of Biomedical Data Science, Stanford University, Stanford, CA 94305"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allan L.","family":"Reiss","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander E.","family":"Urban","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, CA 94305;"},{"name":"Department of Genetics, Stanford University School of Medicine, Stanford, CA 94305;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2020,2,18]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1007\/BF01213097","article-title":"Chromosome abnormalities found among 34,910 newborn children: Results from a 13-year incidence study in Arhus, Denmark","volume":"87","author":"Nielsen J.","year":"1991","unstructured":"J.
