LMNA and Emery-Dreifuss muscular dystrophy: Specifically, mutations in both lamin A (LMNA) and emerin (EMD) lead to Emery-Dreifuss muscular dystrophy (EDMD), utosomal dominant EDMD in LMNA mutations and X-linked EDMD in EMD mutations (Holaska, 2008; Ishikawa et al., 2020), both associated with cardiac arrythmia (Boriani et al., 2003).
