Overview

Genetic analysis identifies SOX5 mutations causing atrial fibrillation, suggesting new therapeutic targets.

Key Points

The study aims to identify genetic variations associated with atrial fibrillation, focusing on the SOX5 gene.
Analyzed a Chinese pedigree with idiopathic AF and 236 additional idiopathic AF cases against 312 healthy volunteers.
Performed exome-wide sequencing and Sanger sequencing on participants.
Conducted dual-luciferase reporter assays to assess functional impacts of SOX5 mutations.
Identified two novel truncating SOX5 mutations in the AF pedigree and one patient.
Both mutations were absent from a control group of 624 chromosomes.
SOX5 mutations resulted in loss of transactivation ability of GJA1 and disrupted synergistic activation with SCN5A.
