WebIt is the aim of this article to abridge the current knowledge of the genetic background of inherited arrhythmogenic diseases, namely long QT syndrome, short QT syndrome, Brugada syndrome and catecholaminergic polymorphic ventricular tachycardia. Pathogenesis and genotype-phenotype correlations are also discussed. Publication types Review WebSome arrhythmias (known as inherited arrhythmias) are caused by genetic factors, which may be passed down from parents to children. While there are many types of arrhythmias, these genetic conditions increase the risk of a life-threatening arrhythmia and therefore require highly specialized care.
WebArrhythmogenic cardiomyopathy (ACM) is a genetically determined myocardial disease, characterized by myocytes necrosis with fibrofatty substitution and ventricular arrhythmias that can even lead to sudden cardiac death. The presence of inflammatory cell infiltrates in endomyocardial biopsies or in autoptic specimens of ACM patients has been reported, … WebDec 1, 2016 · This review will highlight the latest developments in understanding the genetic basis of inherited arrhythmia syndromes …
WebThe largest genetic study to date focused on cardiac causes of SIDS included 419 SIDS cases and studied 90 cardiac arrhythmia and cardiomyopathy genes. 52 This study used appropriately stringent criteria when assigning pathogenicity to genomic variants thus avoiding over-interpreting genetic variants, which has been an issue in previous studies ... WebRBM20 (RNA-binding motif protein 20) is a splicing factor targeting multiple cardiac genes, and its mutations cause cardiomyopathies. Originally, RBM20 mutations were discovered to cause the development of dilated cardiomyopathy by erroneous splicing of the gene TTN (titin). Titin is a giant protein found in a structure of the sarcomere that functions as a …

Conclusions: While damaging cardiomyopathy and arrhythmia genes are recognized contributors to SDY, we also observed an enrichment in epilepsy-related genes in the SDY cohort, and a correlation between rare epilepsy variation and younger age at …
WebSudden death. The symptoms of long QT syndrome appear when the syndrome leads to Torsades de Pointes. During this arrhythmia, your heart can’t pump blood effectively. If your brain doesn’t get enough blood supply, you can faint and have a seizure.
