PLEC gene mutations cause familial disto-proximal myopathy and long QT syndrome mimicking mitochondrial disease

Plectin, a giant multifunctional cytolinker protein, plays a crucial role in orchestrating intermediate filament networks in a wide variety of tissues, as epithelia, skeletal muscle and heart. Mutations of the plectin gene (PLEC) on chromosome 8q24 cause autosomal recessive epidermolysis bullosa simplex with muscular dystrophy (EBS-MD), EBS-MD with myasthenic features, EBS with pyloric atresia, EBS-Ogna, and LGMD2Q. Here we report an Italian family with a distinctive muscle phenotype and autosomal recessive transmission in which Whole Exome Sequencing identified homozygous mutations in PLEC gene.
