RPSA and Arrhythmogenic right ventricular dysplasia: To identified gene associated with the disease, a number of genes located in the critical region of the microsatellite markers were screened, including laminin receptor 1 pseudogene 6 LAMR1P6, which is a processed transposable element within the ARVC6 critical interval (Asano et al., 2004) and a functional lamr1 retroposon gene is a cause of ARVC observed in the mouse via regulating mRNA stability of a homologous gene (Yonemura et al., 1998).
