PKP2 and Arrhythmogenic right ventricular dysplasia: In our efforts to identify the genetic etiology for the clinical presentation for Lody, we sequenced the coding regions and flanking exon-intron boundaries of 10 ARVC-associated genes (LMNA, CTNNA3, DES, TGFB3, JUP, TMEM43, PKP2, DSC2, DSG2, and DSP) in our subject and compared his data to that of an unaffected female bonobo (Kitty).
