Limb–girdle muscular dystrophy or (LGMD) is a genetically and clinically heterogeneous group of rare muscular dystrophies. Mutations in the gene encoding plectin (PLEC) cause two distinct autosomal recessive subtypes of epidermolysis bullosa: EB simplex (EBS) with muscular dystrophy (EBS-MD), and EBS with pyloric atresia (EBS-PA).

Immunoblot analysis of extracts from fibroblasts of the normal control and the proband by using PN643 against the N-terminal actin- binding domain, HD1-121 against the rod domain and C20 against the C-terminal plectin repeats. Introduction Epidermolysis bullosa (EB) is a group of heritable blistering disorders characterized by fragility of the skin within the dermal-epidermal basement membrane zone (BMZ) ( 1 , 2 ). Both of the premature termination codon-causing mutations of the proband are located within exon 32, the last exon of PLEC. … Plectin is a cytoskeletal linker protein which has a long central rod and N‐ and C‐terminal globular domains. Is expressed in epidermis and yolk syncytial layer. Defective expression of plectin/HD1 in epidermolysis bullosa simplex with muscular dystrophy. Epidermolysis bullosa simplex with PLEC mutations: new phenotypes and new mutations. Rodless plectin (arrows), detected with PN643 and C20, migrates just below full-length plectin (arrowheads) in normal human fibroblasts. We report that the skin of three MD-EBS patients is not reactive with antibodies 6C6, 10F6, or 5B3 raised against the intermediate filament-associated protein plectin. 2005 Feb;7(1):28-35. doi: 10.1016/S1525-1578(10)60005-0. Genomics. Previous studies have demonstrated that loss of full-length plectin with residual expression of the rodless isoform leads to EBS-MD, whereas complete loss or marked attenuation of expression of full-length and rodless plectin underlies the more severe EBS-PA phenotype.
