(A) Family members with shared SCN5A mutation exhibit different ECG phenotypes. A father and daughter both positive for a SCN5A mutation exhibit different phenotypes during ajmaline challenge. The father is negative, whereas the daughter is affected by BrS. The son, negative for the SCN5A mutation, is also showing a negative ajmaline test. (B) Family members with shared MYBPC3 mutation exhibit different ECG phenotypes. A father and daughter both positive for a MYBPC3 mutation exhibit different ECG phenotypes during ajmaline challenge. The father is negative, whereas the daughter shows a mild positive response to ajmaline. The son, also positive for the MYBPC3 mutation, exhibits a spontaneous BrS type 1 pattern.
