P.252LGMD, exercise intolerance, ptosis, ophthalmoplegia and dermatologic features: the phenotypic pleiotropy of plectinopathies in 8 French families

Plectin is a giant multifunctional cytolinker protein (500 kDa) expressed in several tissues with essential roles in striated and smooth muscles, epithelia and nerve. It is a component of hemidesmosomes, desmosomes and focal adhesion contacts where it interacts with actin and intermediate filaments. Pathogenic variants in the PLEC1 gene lead to a group of diseases including epidermolysis bullosa (simplex ogna with or without muscular dystrophy, myasthenic syndrome, or pyloric atresia) and isolated limb-girdle muscular dystrophy.
