Abstract 772: The Highly Prevalent 25bp Intronic Deletion in MYBPC3 is Benign Under Baseline Conditions

Background: Hypertrophic cardiomyopathy (HCM) affects at least 1 in 500 people worldwide, and results in the thickening of the ventricular walls and reduced cardiac function. Mutations in MYBPC3 , encoding cardiac myosin binding protein-C, are the most common cause of HCM. Previously, a highly prevalent 25bp deletion within intron 32 of MYBPC3 was described in the South Asian population. The MYBPC3 d25bp variant is present in approximately 100...
