Mutations in FHL1 are associated with at least six different muscular dystrophies including reducing body myopathy (Jokela et al., 2017; Shalaby, Hayashi, Nonaka, Noguchi, & Nishino, 2009), muscular dystrophy (Pen et al., 2015), X‐linked myopathy (Windpassinger et al., 2008) and HCM (Binder, et al., 2012; Friedrich et al., 2012; Kubota, et al., 2019; Liang, et al., 2018; Willis, et al., 2016). Here, FHL1 is linked to muscular dystrophy.
