We report the case of a female infant with EIEE and strikingly suppressed respiratory dysfunction that led to death. Postmortem research evaluation revealed hypoplasia of the arcuate nucleus of the medulla, a candidate region for respiratory regulation. Genetic evaluation revealed heterozygous variants in the related genes <jats:italic>NRXN1<\/jats:italic> (c.2686C&gt;T, p.Arg896Trp) and <jats:italic>NRXN2<\/jats:italic> (c.3176G&gt;A, p.Arg1059Gln), one inherited from the mother with family history of sudden infant death syndrome (SIDS) and one from the father with family history of febrile seizures. Although there are no previous reports with the digenic combination of <jats:italic>NRXN1<\/jats:italic> and <jats:italic>NRXN2<\/jats:italic> variants, patients with biallelic loss of <jats:italic>NRXN1<\/jats:italic> in humans and double neurexin 1\u03b1\/2\u03b1 knockout mice have severe breathing abnormalities, corresponding to the respiratory phenotype of our patient. These observations and the known interaction between the <jats:italic>NRXN1<\/jats:italic> and <jats:italic>NRXN2<\/jats:italic> proteins lead us to hypothesize that digenic variants in <jats:italic>NRXN1<\/jats:italic> and <jats:italic>NRXN2<\/jats:italic> contributed to the phenotype of EIEE, arcuate nucleus hypoplasia, respiratory failure, and death.<\/jats:p>","DOI":"10.1101\/mcs.a003442","type":"journal-article","created":{"date-parts":[[2019,2,1]],"date-time":"2019-02-01T19:49:35Z","timestamp":1549050575000},"page":"a003442","source":"Crossref","is-referenced-by-count":28,"title":["Mutations in <i>NRXN1<\/i> and <i>NRXN2<\/i> in a patient with early-onset epileptic encephalopathy and respiratory depression"],"prefix":"10.1101","volume":"5","author":[{"given":"Anne M.","family":"Rochtus","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Trowbridge","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3770-2191","authenticated-orcid":false,"given":"Richard D.","family":"Goldstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beth Rosen","family":"Sheidley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0871-115X","authenticated-orcid":false,"given":"Sanjay P.","family":"Prabhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Haynes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5199-279X","authenticated-orcid":false,"given":"Hannah C.","family":"Kinney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7350-5136","authenticated-orcid":false,"given":"Annapurna H.","family":"Poduri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[2019,2,1]]},"reference":[{"key":"2021112406073477000_5.1.a003442.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pediatrneurol.2012.06.002"},{"key":"2021112406073477000_5.1.a003442.2","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.b.32148"},{"key":"2021112406073477000_5.1.a003442.3","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awl357"},{"key":"2021112406073477000_5.1.a003442.4","doi-asserted-by":"publisher","DOI":"10.1186\/2049-9256-1-4"},{"key":"2021112406073477000_5.1.a003442.5","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.35780"},{"key":"2021112406073477000_5.1.a003442.6","doi-asserted-by":"publisher","DOI":"10.1038\/tp.2014.123"},{"key":"2021112406073477000_5.1.a003442.7","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.b.32036"},{"key":"2021112406073477000_5.1.a003442.8","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0910297106"},{"key":"2021112406073477000_5.1.a003442.9","doi-asserted-by":"publisher","DOI":"10.1097\/00005072-199207000-00002"},{"key":"2021112406073477000_5.1.a003442.10","doi-asserted-by":"publisher","DOI":"10.1002\/cne.902930308"},{"key":"2021112406073477000_5.1.a003442.11","first-page":"659","article-title":"Primary alveolar hypoventilation (Ondine's curse syndrome) in an infant without external arcuate nucleus.
