MYPN and cardiomyopathy: Based on its similarity to MYPN, associated with different forms of cardiomyopathy (Bagnall et al., 2010; Duboscq-Bidot et al., 2008; Meyer et al., 2013; Purevjav et al., 2012), as well as high expression levels of specific PALLD isoforms in cardiac muscle both during development and at adult stage, we hypothesized that PALLD plays an important role also in the heart (Wang and Moser, 2008).
