TTN and arrhythmogenic right ventricular cardiomyopathy: Five rare variants were identified after the filtering procedure in Pt-1 and Pt-4 (EYA4 p.Pro170Thr, TTN p.Glu22134Lys, and VCL p.Pro291Gln in Pt-1 and RYR2 p.Val1810Leu and TTN p.Arg22007Cys in Pt-4); however, based on previous studies and genetic databases, it was not evident whether these variants were related to the development of ARVC in Pt-1 or HCM in Pt-4.
