TTN and autosomal dominant centronuclear myopathy: Recessive skeletal myopathies associated with TTN include limb‐girdle muscular dystrophy type 2 J (LGMD2 J or LGMDR10; caused by the TMD‐related M‐band deletion in the homozygous state; Evila, 2014; Hackman et al., 2002), and centronuclear myopathy (caused by recessive truncating or in‐frame deletions/duplications; Ceyhan‐Birsoy et al., 2013).
