We present a family from a founder population referred for cardiogenetic evaluation for atrioventricular block in 3 siblings. Genetic testing, including whole-exome sequencing, did not identify a disease-causing mutation. After reconsidering the differential diagnosis, a nongenetic cause was identified. This case highlights the importance of a thorough clinical evaluation even when a genetic cause is seemingly obvious.
