To identify novel genetic risk loci associated with Brugada syndrome and characterize molecular mechanisms regulating sodium channel expression in disease susceptibility.
Conducted genome-wide association analyses to identify genetic loci associated with Brugada syndrome risk.
Evaluated molecular mechanisms underlying sodium channel Nav1.5 regulation and expression.
Identified new risk loci that expand the known polygenic architecture of Brugada syndrome.
Demonstrated that altered sodium channel expression acts as a key molecular mechanism underlying genetic susceptibility to Brugada syndrome.

Structured PICO

Population

Patients with Brugada syndrome (BrS)

Intervention

Genome-wide association analyses

Outcome

Identification of new Brugada syndrome risk loci and mechanism of sodium channel regulation

The study broadens the understanding of the genetic architecture of Brugada syndrome by identifying new risk loci and molecular mechanisms.

Implication

Expands BrS genetic architecture; leaves open functional validation and any clinical translation.

Abstract

1.5 expression as a new underlying molecular mechanism. Taken together, these findings broaden our understanding of the genetic architecture of BrS and provide new insights into its molecular underpinnings.
