A Case of Cardiogenic Stroke With a Novel LMNA Variant (c. 1135C>A; p.Leu379Ile).

Laminopathy is muscular dystrophy caused by an LMNA gene mutation. It is characterized by cardiac disease such as atrial fibrillation. We report a case of laminopathy in a 49-year-old woman who presented with cardiogenic stroke. She had experienced weakness in her limb-girdle muscles since childhood, atrial fibrillation, cardiomyopathy, and mild contracture of the ankle joints, and had a familial history of heart disease. Gene analysis identified a novel heterozygous variant, c. 1135C>A (p.Leu379Ile), in the LMNA gene. Laminopathy can be an underlying disease in ischemic stroke, especially in young to middle age.
