MS-0373

A 26-year-old man collapses during a game of cricket. He has previously experienced chest pain and shortness of breath while running, which subsides on rest. Upon examination, he is found to have an ejection systolic murmur that intensifies with Valsalva maneuvers and diminishes with squatting. His echocardiogram reveals mitral regurgitation, asymmetric hypertrophy, and systolic anterior motion of the anterior mitral valve leaflet. What is the expected inheritance pattern for this diagnosis?
