Nevertheless, MmD is also caused by mutations in SELENON (Ferreiro et al., 2002a; Kazamel and Milone, 2019), MYH7 (Cullup et al., 2012), ACTA1 (Kaindl, 2004), ACTN2 (Lornage et al., 2019), TTN (Chauveau et al., 2014), MEGF10 (Boyden et al., 2012; Takayama et al., 2016), CCDC78 (Kazamel and Milone, 2019) and FXR1 (Estañ et al., 2019) (Box 3), prompting the development of several non-ryanodine core myopathy models. Here, MYH7 is linked to multiminicore myopathy.
