Approximately 65% of patients with CPVT are found to have a disease causing mutation in the <jats:italic>RYR2<\/jats:italic> gene. <jats:italic>RYR2<\/jats:italic> encodes a calcium ion transporter in the sarcomeric reticulum, and is responsible for the calcium induced calcium release that results in ventricular contraction. Recently, exon 3 deletion of <jats:italic>RYR2<\/jats:italic> has been reported to be associated with left ventricular noncompaction. Herein we describe a patient with a novel, de novo deletion of exon 3 in the <jats:italic>RYR2<\/jats:italic> gene that resulted in a severe CPVT phenotype and sudden cardiac arrest (SCA), and the development of left ventricular non\u2010compaction (LVNC) coinciding with worsening arrhythmias. This case is unique in that the patient initially presented with exertional syncope and developed LVNC that coincided with increasingly severe ventricular arrhythmias and multiple episodes of SCA. This case supports the idea that <jats:italic>RYR2<\/jats:italic> deletions cause a severe subtype of CPVT associated with LVNC and suggests LVNC may play a role in exacerbating the arrhythmias of CPVT. Deletion duplication testing should be considered in the context of CPVT and LVNC or SCA. \u00a9 2015 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajmg.a.37140","type":"journal-article","created":{"date-parts":[[2015,5,28]],"date-time":"2015-05-28T04:01:40Z","timestamp":1432785700000},"page":"2197-2200","source":"Crossref","is-referenced-by-count":46,"title":["Exon 3 deletion of ryanodine receptor causes left ventricular noncompaction, worsening catecholaminergic polymorphic ventricular tachycardia, and sudden cardiac arrest"],"prefix":"10.1002","volume":"167","author":[{"given":"Matthew J.","family":"Campbell","sequence":"first","affiliation":[{"name":"Department of Pediatrics Cincinnati Children's Hospital Medical Center Cincinnati Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard J.","family":"Czosek","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Cincinnati Children's Hospital Medical Center, The Heart Institute Cincinnati Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert B.","family":"Hinton","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Cincinnati Children's Hospital Medical Center, The Heart Institute Cincinnati Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin M.","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Cincinnati Children's Hospital Medical Center, The Heart Institute Cincinnati Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,5,27]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eur245"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.711606"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humpath.2005.04.019"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardfail.2009.01.006"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pcad.2007.10.005"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehq508"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eut382"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCRESAHA.111.256560"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.a.37140","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.37140","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T14:52:26Z","timestamp":1696603946000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.37140"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,5,27]]},"references-count":8,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2015,9]]}},"alternative-id":["10.1002\/ajmg.a.37140"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.37140","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,5,27]]}}}
