Expression patterns of SLRPs are altered in Duchenne muscular dystrophy (DMD) and muscle injury (Casar et al., 2004, Fadic et al., 2006, Zanotti et al., 2005), and Dcn and Fmod have been implicated in regulating myogenesis (Brandan et al., 2008, Brandan and Gutierrez, 2013, Jan et al., 2016). This evidence concerns the gene DCN and Duchenne muscular dystrophy.
