Most demonstrate recessive inheritance and do not cause cardiomyopathy, including LGMD2J (a severe, early‐onset LGMD caused by a homozygous 11‐bp deletion/insertion in the M‐line), centronuclear myopathy, and TTN‐associated distal myopathy (both caused by recessive truncating or in‐frame deletions/duplications; Savarese, Sarparanta, Vihola, Udd, & Hackman, 2016). The gene discussed is TTN; the disease is centronuclear myopathy.
