Elevated hs-cTnT levels were found to be associated with all three echocardiographic parameters (risk factors for SCD) (maximum left ventricular thickness, provocable left ventricular outflow tract gradient (LVOTG), left atrial diameter) recommended by the European Society of Cardiology for assessing the prognosis of HCM patients [58]. The gene discussed is TNNT2; the disease is Schnyder corneal dystrophy.
