From a long-term management standpoint, women with PWS who are also DMD carriers should receive cardiomyopathy surveillance in accordance with carrier care recommendations (e.g., baseline and periodic assessment with echocardiography and/or cardiac MRI) alongside standard PWS management and reproductive counseling (Birnkrant et al., 2018; Feingold et al., 2017). Here, DMD is linked to cardiomyopathy.
