Core Tip

Core Tip: The presence of sarcomere mutations makes the prognosis of hypertrophic cardiomyopathy (HCM) patients worse. Compared with the two most common thick myofilament genes, MYH7 carriers have an earlier onset of HCM. Compared with patients with thick myofilament gene mutations, patients with thin myofilament mutations have a worse prognosis. Among patients with thin myofilament gene mutations, TNNC1 positive probands have the worst prognosis. In this paper, the close relationship between HCM hypertrophy pattern and genetic variation was combed and insights were put forward, which provided a theoretical basis for genetic testing and personalized management of HCM patients.
