"Six gene variants were found including a novel missense mutation of base C to T, named Arg965 Cys (R965C), which located in 965 codon of the 17 exon in SCN5A, and five SCN5A polymorphisms including A29A (c. 87A> G), R1193Q (c. 3578G> A), D1819D (c. 5457T> C), exon11 -24 G> A, exon23 +4 A> G. SCN5A mutation is related to fever induced Brugada ECG pattern."

"Heavy metals like zinc and copper can serve as endogenous regulators of sodium, potassium, and calcium channels, including NaV1.5 sodium channel, which might possibly produce a Brugada ECG pattern ."

"The SCN5A–SCN10A locus (lead SNP rs10428132) was significantly associated with ajmaline-induced Type I BrS ECG (P = 8.6 × 10 )."

reach
"The activity of REs is largely limited to target genes that fall within the same TAD , including SCN5A, SCN10A, EXOG, SCN11A, and WDR48.GWAS have identified genetic variants in the SCN5A-SCN10A locus that modulate ECG parameters and contribute to conduction diseases."

reach
"Over-expression of the SCN5A gene leads to a shorter P wave duration and PR interval in transgenic mice ECG [16], which suggests that Na 1.5 interference or blockade caused prolonged P wave duration, as observed in this report.Isorubijervine and rubijervine treatment shortened the QT interval in rats (Figure 2), which is the same as other sodium channel blockers."

"Conclusion: Short-term treatment with antidepressant drugs increase DNA methylation in KCNE1 and SCN5A promoters, which may induce ECG alterations in psychiatric patients."
