Summary

Story summary

Recent genome-wide association studies examine genetic factors in Brugada syndrome (BrS).
Researchers identified multiple single-nucleotide polymorphisms at SCN5A and SCN10A linked to BrS risk.
A rare SCN5A variant is enriched in Thai BrS cases, increasing sodium current density.
The studies suggest BrS arises when accumulated genetic and environmental risks exceed a disease threshold.
Specific genetic variations may explain male prevalence in Asian populations.
