case_images: (A) Identification of the heterozygous c.4700_4701del deletion by next generation sequencing. NGS paired-end reads loaded in the IGV genome browser. The gene sequence is in the reverse orientation on the chromosome. (B) Identification of the heterozygous c.4700_4701del deletion by sanger sequencing. Sanger sequencing confirmation of the deletion compared with the wild-type sequence. The wt (black) and mutated (red) sequences are reported. The position of the two bases deleted is indicated by the red arrow. Black arrows indicate the direction of the gene. (C) Family pedigree. Proband identified with an arrow. Square: male; Circle: female; Shaded: clinically affected by Brugada syndrome; Star: molecularly confirmed SCN5A mutation: Triangle: genetically tested and negative for SCN5A mutation.

case_images: Genetic testing revealed the variant c.4700_4701del (p.Phe1567Cysfs*221) in a single copy of the SCN5A gene (Figure 2).
