DCHS1 and mitral valve disorder: Chugh et al. (2004) [30], among their SCD group, described two cases of Wolff-Parkinson-White (diagnosed on the 12-lead ECG); in their article, Neubauer et al. (2016) [14] described mutations in DCHS1 and TGFB2, related to Mitral valve prolapse (associated with mild systemic features of Marfan syndrome) that comport a SCD.
