Both conditions are predominantly caused by\n                    <jats:italic>de novo<\/jats:italic>\n                    missense or nonsense mono-allelic variants. They are characterized by a generalized developmental delay, intellectual disability, behavioral problems (hyperactivity, repetitive movements and social interaction deficits), hypotonia, motricity and verbalization deficits. One of the main features of POBINDS is epilepsies, which are present with much lower prevalence in patients with OCNDS. While a role for CK2 in brain functioning and development is well acknowledged, these findings for the first time clearly link CK2 to defined brain disorders. Our review will bring together patient data for both syndromes, aiming to link symptoms with genotypes, and to rationalize the symptoms through known cellular functions of CK2 that have been identified in preclinical and biochemical contexts. We will also compare the symptomatology and elaborate the specificities that distinguish the two syndromes.\n                  <\/jats:p>","DOI":"10.3389\/fmolb.2022.850559","type":"journal-article","created":{"date-parts":[[2022,5,26]],"date-time":"2022-05-26T04:05:57Z","timestamp":1653537957000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":24,"title":["Comparing Two Neurodevelopmental Disorders Linked to CK2: Okur-Chung Neurodevelopmental Syndrome and Poirier-Bienvenu Neurodevelopmental Syndrome\u2014Two Sides of the Same Coin?"],"prefix":"10.3389","volume":"9","author":[{"given":"Demetra","family":"Ballardin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose M.","family":"Cruz-Gamero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Bienvenu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heike","family":"Rebholz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,5,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1037","DOI":"10.1097\/00001813-200511000-00001","article-title":"Targeting CK2 for Cancer Therapy","volume":"16","author":"Ahmad","year":"2005","journal-title":"Anti-Cancer Drugs"},{"key":"B2","doi-asserted-by":"publisher","first-page":"18011","DOI":"10.1038\/hgv.2018.11","article-title":"Refining the Clinical Phenotype of Okur-Chung Neurodevelopmental Syndrome","volume":"5","author":"Akahira-Azuma","year":"2018","journal-title":"Hum.
