A novel homozygous mutation in the TRDN gene causes a severe form of pediatric malignant ventricular arrhythmia

摘要

BACKGROUND Triadin is a protein expressed in cardiac and skeletal muscle that has an essential role in the structure and functional regulation of calcium release units and excitation-contraction coupling. Mutations in the triadin gene (TRDN) have been described in different forms of human arrhythmia syndromes with early onset and severe arrhythmogenic phenotype, including triadin knockout syndrome.
