Patients with BrS can be asymptomatic or present with symptoms secondary to polymorphic ventricular tachycardia or ventricular fibrillation. Even though BrS can exhibit autosomal dominant inheritance, it is not easy to identify the phenotype and genotype in a family thoroughly.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case<\/jats:title><jats:p>We report the case of a 20-year-old man with variants in <jats:italic>SCN5A<\/jats:italic> and <jats:italic>RyR2<\/jats:italic> genes who was resuscitated from sudden cardiac death during sleep due to a ventricular fibrillation. The patient did not have underlying diseases. The routine laboratory results, imaging study, coronary angiogram, and echocardiogram (ECG) were normal. A type 1 BrS pattern was identified in one resting ECG. Furthermore, prominent J wave accentuation with PR interval prolongation was identified during therapeutic hypothermia. Therefore, we were easily able to diagnose BrS. For secondary prevention, the patient underwent implantable cardioverter defibrillator implantation. Before discharge, a genetic study was performed using next-generation sequencing. Genotyping was performed in the first-degree relatives, and ECG evaluations of almost all maternal and paternal family members were conducted. The proband and his mother showed <jats:italic>SCN5A-R376H<\/jats:italic> and <jats:italic>RyR2-D4038Y<\/jats:italic> variants<jats:italic>.<\/jats:italic> However, his mother did not show the BrS phenotype on an ECG. One maternal aunt and uncle showed BrS phenotypes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Genetics alone cannotdiagnose BrS. However, genetics could supply evidence or direction for evaluating ECG phenotypes in family groups. This case report shows how family evaluation using ECGs along with a genetic study can be used in BrS diagnosis.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2024.1334096","type":"journal-article","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T04:31:10Z","timestamp":1710477070000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Comprehensive evaluation of ECG phenotypes and genotypes in a family with Brugada syndrome carrying SCN5A-R376H"],"prefix":"10.3389","volume":"11","author":[{"given":"Ngoc Bao","family":"Ly","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoo Ri","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ki Hong","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Namsik","family":"Yoon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung Wook","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,3,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"151","DOI":"10.1016\/j.ijcard.2017.11.113","article-title":"Prevalence of spontaneous Brugada ECG pattern recorded at standard intercostal leads: a meta-analysis","volume":"254","author":"Shi","year":"2018","journal-title":"Int J Cardiol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"652027","DOI":"10.3389\/fcvm.2021.652027","article-title":"Evaluating the use of genetics in Brugada syndrome risk stratification","volume":"8","author":"Monasky","year":"2021","journal-title":"Front Cardiovasc Med"},{"key":"B3","doi-asserted-by":"publisher","first-page":"3997","DOI":"10.1093\/eurheartj\/ehac262","article-title":"2022 ESC guidelines for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death","volume":"43","year":"2022","journal-title":"Eur Heart J"},{"key":"B4","doi-asserted-by":"publisher","first-page":"433","DOI":"10.1016\/j.jelectrocard.2012.06.004","article-title":"Current electrocardiographic criteria for diagnosis of Brugada pattern: a consensus report","volume":"45","author":"de Luna","year":"2012","journal-title":"J Electrocardiol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"1561","DOI":"10.2174\/1381612053764823","article-title":"Specific therapy based on the genotype and cellular mechanism in inherited cardiac arrhythmias.
