His paternal uncle had an EKG that was significant for sinus bradycardia, a first-degree atrioventricular block (AVB), and an intraventricular conduction delay (IVCD) greater than 110 milliseconds (ms) (Figure 3). His paternal half-aunt had a history of SCD at the age of 52; her daughter was also found to carry the variant and had a history of palpitations and an EKG with sinus bradycardia and an IVCD of 113 ms (Figure 4). His half-sister who was found to have the SCN5A genetic variant had a type 1 Brugada EKG when she had a fever. The gene discussed is SCN5A; the disease is Schnyder corneal dystrophy.
