Recent studies have indicated that mutations in four and-a-half LIM domain protein 1 (FHL1) are associated with rare hereditary myopathies, including reducing body myopathy (RBM), X-Linked myopathy with postural muscle atrophy (XMPMA), Emery-Dreifuss muscular dystrophy (EDMD), and cardiomyopathies (Kley et al., 2016; Xue et al., 2016; Ehsan et al., 2017; Pillar et al., 2017; Le Thanh et al., 2017). Here, FHL1 is linked to X-linked myopathy with postural muscle atrophy.
