Long QT syndrome (LQTS) is an inherited cardiac disease characterized by a prolonged heart rate-corrected QT (QTc) interval. We investigated the genetic causes in patients with prolonged QTc intervals who were negative for pathogenic variants in three major LQTS-related genes (KCNQ1, KCNH2, and SCN5A). Molecular genetic testing was performed using a panel including 13 LQTS-related genes and 67 additional genes implicated in other cardiac diseases. Overall, putative genetic causes of prolonged…

Highlight article: Dysfunctional Cav1.2 channel in Timothy syndrome, from cell to bedside
A detailed review of Timothy syndrome is provided, the mechanisms underlying dysfunctional Cav1.2 due to CACNA1C mutations are discussed, and some new emerging evidences in treating Timothy syndrome from cell to bedside are provided, promoting the management of this rare disease.
Penetrance and expressivity of the R858H CACNA1C variant in a five‐generation pedigree segregating an arrhythmogenic channelopathy
A large pedigree is described, from which estimates of penetrance and expressivity of isolated cardiac arrhythmia due to a variant in CACNA1C are calculated.


The genetics underlying acquired long QT syndrome: impact for genetic screening.
The probability of being a carrier of cLQTS disease-causing mutations can be predicted by simple clinical parameters, thus allowing possibly cost-effective genetic testing leading to cascade screening for identification of additional at-risk family members.
Founder mutations characterise the mutation panorama in 200 Swedish index cases referred for Long QT syndrome genetic testing
The mutation panorama is characterised by founder mutations (25%), even so, this cohort increases the amount of known LQTS-associated mutations, as approximately one-third (28%) of the detected mutations were unique.
Identification and Functional Characterization of a Novel CACNA1C-Mediated Cardiac Disorder Characterized by Prolonged QT Intervals With Hypertrophic Cardiomyopathy, Congenital Heart Defects, and Sudden Cardiac Death
Electrophysiological studies, identification of mutations at the same amino acid position in multiple pedigree, and cosegregation with disease in these pedigrees provide evidence that p.Arg518Cys/His is the pathogenic substrate for the observed phenotype.
Results of genetic testing in 855 consecutive unrelated patients referred for long QT syndrome in a clinical laboratory.
Sequencing-based genetic testing has a sensitivity of 72% and has clinical utility and factors that predicted the likelihood of a disease causing mutation using ANOVA, χ2, t-test, and receiver operator curves are analyzed.
Exome Analyses of Long QT Syndrome Reveal Candidate Pathogenic Mutations in Calmodulin-Interacting Genes
An important role of calmodulin and its interacting proteins in the pathogenesis of LQ TS is suggested, with ten new pathogenic candidates that directly or indirectly interact with proteins encoded by known LQTS genes.
Genotype- and phenotype-guided management of congenital long QT syndrome.
The X-linked gene G4.5 is responsible for different infantile dilated cardiomyopathies.
The sequence analysis of 11 additional familial cases is reported, which suggests that very severe phenotypes may be associated with null mutations in the gene, whereas mutations in alternative portions or missense mutations may give a "less severe" phenotype.
A Novel Disease Gene for Brugada Syndrome: Sarcolemmal Membrane–Associated Protein Gene Mutations Impair Intracellular Trafficking of hNav1.5
The mutations in SLMAP may cause Brugada syndrome via modulating the intracellular trafficking of hNav1.5 channel through modification of T-tubules and sarcoplasmic reticulum.
