[[http://www.uniprot.org/uniprot/PLEC_HUMAN PLEC_HUMAN]] Defects in PLEC are the cause of epidermolysis bullosa simplex with pyloric atresia (EBS-PA) [MIM:[http://omim.org/entry/612138 612138]]. EBS-PA is an autosomal recessive genodermatosis characterized by severe skin blistering at birth and congenital pyloric atresia. Death usually occurs in infancy. This disorder is allelic to MD-EBS.<ref>PMID:8698233</ref> <ref>PMID:20665883</ref> <ref>PMID:14675180</ref> Defects in PLEC are the cause of epidermolysis bullosa simplex with muscular dystrophy (MD-EBS) [MIM:[http://omim.org/entry/226670 226670]]. MD-EBS is an autosomal recessive disorder characterized by epidermal blister formation at the level of the hemidesmosome and associated with late-onset muscular dystrophy. Defects in PLEC are the cause of epidermolysis bullosa simplex Ogna type (O-EBS) [MIM:[http://omim.org/entry/131950 131950]]; also called epidermolysis bullosa simplex 1. O-EBS is a form of intraepidermal epidermolysis bullosa characterized by generalized skin bruising, skin fragility with non-scarring blistering and small hemorrhagic blisters on hands. At the ultrastructural level, it is differentiated from classical cases of K-EBS, WC-EBS and DM-EBS, by the occurrence of blisters originating in basal cells above hemidesmosomes, and abnormal hemidesmosome intracellular attachment plates. Defects in PLEC are the cause of limb-girdle muscular dystrophy type 2Q (LGMD2Q) [MIM:[http://omim.org/entry/613723 613723]]. An autosomal recessive degenerative myopathy characterized by early childhood onset of proximal muscle weakness. Note=A 9 bp deletion containing the initiation codon in exon 1f of PLEC have been found in limb-girdle muscular dystrophy patients. The mutation results in deficient expression of isoform 9 and disorganization of the myofibers, without any effect on the skin.<ref>PMID:21109228</ref> <ref>PMID:8698233</ref> | |||
== Function == | |||
[[http://www.uniprot.org/uniprot/PLEC_HUMAN PLEC_HUMAN]] Interlinks intermediate filaments with microtubules and microfilaments and anchors intermediate filaments to desmosomes or hemidesmosomes. Could also bind muscle proteins such as actin to membrane complexes in muscle. May be involved not only in the filaments network, but also in the regulation of their dynamics. Structural component of muscle. Isoform 9 plays a major role in the maintenance of myofibers integrity.<ref>PMID:12482924</ref> <ref>PMID:21109228</ref> | |||
