TTN and myocarditis: Another recent study performed next generation DNA sequencing on 36 patients with biopsy-confirmed myocarditis and found that 31% had evidence of genetic variants that have been associated with cardiomyopathy including Titin (TTN) (n = 8), Desmoplakin (DSP) (n = 1), Filamin C (FLNC) (n = 1) and RNA binding protein 20 (RBM20) (n = 1) (77).
