Furthermore, Fernlund et al., discovered no difference regarding circulating myostatin concentration in the serum of young patients with hypertrophic cardiomyopathy in comparison to healthy controls, despite lower myostatin levels in patients at risk of this disorder, which indicates a potential role of myostatin in the development of hypertrophic cardiomyopathy [173]. The gene discussed is MSTN; the disease is hypertrophic cardiomyopathy.
