Abstract

Introduction: Brugada syndrome (BrS) is an inherited cardiac arrhythmia that causes sudden death. Mutations in the SCN5A gene, which codes for the sodium channel, have been identified as a cause of Brugada syndrome. These are autosomal dominant inheritance. Genealogical research is one of the approaches to genetic diseases. Objectives: To describe the two pedigrees of BrS patients who had pathogenic mutations in SCN5A gene. Subjects and methods: The patients were diagnosed with BrS, have been identified as having a pathogenic SCN5A gene mutation and the patient's family members. Record the history and clinical features of everyone in the families. SCN5A gene mutation status was determined by Sanger gene sequencing technique. Using protein function prediction softwares to investigate the pathogenicity of the mutations. Results: Family 1 includes the patient and 4 members, having N109del mutation (pathogenic) in exon 3 and R1193Q mutation (benign) in exon 20. Family 2 includes the patient and 6 members, having R659W mutation (pathogenic) in exon 13.
