The essential role of plectin in the latter is highlighted by the observation that mutations in the human plectin gene (PLEC) on chromosome 8q24 cause a variety of rare human disorders (referred to as “plectinopathies”), namely autosomal recessive epidermolysis bullosa simplex with muscular dystrophy (EBS-MD, MIM #226670), EBS-MD with myasthenic features (EBS-MD-MyS), limb girdle muscular dystrophy type 2Q (LGMD2Q, MIM #613723), EBS with pyloric atresia (EBS-PA, MIM #612138), and the autosomal dominant variant EBS-Ogna [23, 25]. The gene discussed is PLEC; the disease is muscular dystrophy.
