The term phenocopy indicates a condition that imitates one produced by a gene and is also used for acquired Brugada-like ECG manifestations. Cases of Brugada phenocopies are increasingly reported in literature and an international registry is ongoing. We describe two patients with Hypertrophic Cardiomyopathy (HCM) and Brugada ECG pattern. Both patients carried the same pathogenic splicing mutation in MYBPC3 gene (responsible for HCM) while no genetic mutation associated with Brugada Syndrome was identified. To the best of our knowledge, Brugada ECG pattern has been rarely reported in patients with HCM.
