In EBSPA, expression of all plectin domains was found to be markedly attenuated or completely lost. In EBSMD, the expression of the N- and C-terminal domains of plectin remained detectable, although the expression of rod domains was absent or markedly reduced. The findings suggested that loss of the full-length plectin isoform with residual expression of the rodless plectin isoform leads to EBSMD, but that complete loss or marked attenuation of both the full-length and rodless plectin isoforms underlies the more severe EBSPA phenotype. In addition, the majority of EBSMD-associated PLEC1 mutations occurred within the large exon 31 that encodes the plectin rod domain.

The phenotype was characterized by early childhood onset of proximal muscle weakness and atrophy, and, in 1 family, progression of the disorder in adolescence. There was no skin involvement. Muscle biopsy from an affected individual showed significantly (100-fold) decreased expression of plectin isoform-1f mRNA and a 3-fold decrease of the plectin protein. Examination of control skeletal muscle with antibodies against the rod domains of all plectin isoforms showed strong sarcoplasmic staining, but irregular and weak sarcolemmal staining of type 2 fibers, and only rare and faint staining for type 1 fibers. In patient muscle, there was no sarcolemmal staining of type 2 fibers. Electron microscopic studies of patient muscle showed empty spaces between the sarcolemma and the contractile elements of the sarcomere, separation of membranes, loss of myofibrillar organization in some areas, and misalignment of the Z lines. These findings suggested that isoform 1f is a sarcolemma-associated protein with a specific role in skeletal muscle, and that lack of this isoform results in disruption of the myofiber without affecting other tissues. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=21109228" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<strong>Description</strong>

</div>
<span class="mim-text-font">
<p>The PLEC1 gene encodes plectin-1, a 500-kD intermediate filament-binding protein that is one of the largest polypeptides known. It was originally identified as a major component of intermediate filament preparations obtained from cultured cells (Pytela and Wiche, 1980). It is believed to provide mechanical strength to cells and tissues by acting as a crosslinking element of the cytoskeleton. </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Liu et al. (1996) cloned and characterized the human plectin gene by screening a placenta cDNA library with previously published human plectin probes (Wiche et al., 1991) and probes derived from rat plectin. The deduced protein sequences for human and rat plectin are 93% identical. </p><p>McLean et al. (1996) also cloned and sequenced the PLEC1 gene. They showed that the predicted 518-kD polypeptide has homology to the actin-binding domain of the dystrophin family at the amino terminus, a central rod domain, and homology to the intermediate filament-associated protein desmoplakin at the carboxy terminus. </p><p>By RT-PCR, Kazerounian et al. (2002) surveyed the tissue distribution of several plakin family members, including periplakin (602871), plectin, desmoplakin (125647), BPAG1 (113810), and envoplakin (601590). Plectin was expressed in all adult and fetal tissues examined except leukocytes. Only a weak band was obtained from adult brain and thymus. </p><p>Natsuga et al. (2010) determined that human fibroblasts express 2 different plectin isoforms: a 500-kD full-length protein and a 390-kD protein lacking the rod domain. Immunoblot assays found that the quantitative ratio of full-length/rodless plectin was 14.2:1 in fibroblasts, 21.3:1 in keratinocytes, and 1.37:1 in skeletal muscle. </p>

They used the rat plectin cDNA sequence to screen the GenBank database for homologous sequences and identified an expressed sequence tag, EST25263, which demonstrated 84% nucleotide homology and 94% protein homology with the 3-prime region of the rat plectin sequence. Using human-specific oligonucleotide primers designed from the sequence data, they screened a monochromosomal somatic cell hybrid panel by PCR amplification and assigned the gene to chromosome 8. Further localization to 8q24.13-qter was achieved using a panel of deletion-translocation hybrids, thus refining the data from fluorescence in situ hybridization analysis that localized the gene to 8q24 (Liu et al., 1996). </p><p>McLean et al.

<p><strong><em>Epidermolysis Bullosa Simplex 5B, with Muscular Dystrophy</em></strong></p><p>
In affected members of a family with epidermolysis bullosa simplex with muscular dystrophy (EBS5B; 226670), Smith et al. (1996) identified a homozygous frameshift mutation in the plectin gene (601282.0001). They speculated that the absence of the large multifunctional cytoskeleton protein could account for structural failure in both muscle and skin. </p><p>Pulkkinen et al. (1996) reported ultrastructural studies and molecular genetic analysis of plectin in 2 probands from different families with EBSMD. In a proband and in her affected sister, they detected a homozygous 9-bp deletion mutation (601282.0002). The proband in the second family demonstrated a single nucleotide deletion (601282.0003) which resulted in a frameshift and a premature termination codon 16 bp downstream of the mutation. Based on ultrastructural studies Pulkkinen et al. (1996) concluded that plectin was critical for binding of the intermediate keratin filament network to hemidesmosomal complexes. They also postulated that plectin functioned in muscle as a putative attachment protein mediating binding of actin to membrane complexes. </p><p><strong><em>Epidermolysis Bullosa Simplex 5A, Ogna Type</em></strong></p><p>
Koss-Harnes et al. (2002) found the same heterozygous missense mutation (601282.0005) in the original Norwegian family with epidermolysis bullosa simplex Ogna type (EBS5A; 131950) and in an unrelated German family. The authors concluded that these 2 mutations arose about 200 years apart. </p><p><strong><em>Epidermolysis Bullosa Simplex 5C, with Pyloric Atresia</em></strong></p><p>
Pfendner and Uitto (2005) reported 4 consanguineous families in which at least 1 member had EBS with pyloric atresia (EBS5C; 612138). All patients had extensive blistering at birth with pyloric atresia, most had aplasia cutis, and all died from complications of the disorder shortly after birth. Molecular analysis confirmed homozygous mutations in the PLEC1 gene (see, e.g., 601282.0007 and 601282.0009). Pfendner and Uitto (2005) noted that 1 of the mutations deleted a region that may be important for plectin interaction with alpha-6 (ITGA6; 147556)/beta-4 (ITGB4; 147557) integrin, and that mutations in the latter genes result in the phenotypically similar junctional EB-PA (e.g., JEB5B, 226730). Thus, pyloric atresia in all of these patients is likely related to perturbed interactions between plectin and alpha-6/beta-4 integrin within attachment structures expressed during gastrointestinal development. </p><p><strong><em>Epidermolysis Bullosa Simplex 5D, With Nail Dystrophy</em></strong></p><p>
In 2 Turkish sisters with epidermolysis bullosa simplex and nail dystrophy (EBS5D; 616487), Gostynska et al. (2015) identified homozygosity for a nonsense mutation (R16X; 601282.0014) present only in the 1a isoform of PLEC1. Because isoform-1a is not expressed in either striated or cardiac muscle tissue, the authors stated that they did not expect these patients to develop muscular dystrophy or cardiomyopathy. </p><p>In 2 unrelated patients with EBS and nail dystrophy, Tu et al. (2020) identified compound heterozygosity for a missense mutation (L319P; 601282.0015) and 2 different nonsense mutations: R2319X (601282.0013) in one patient and W936X (601282.0016) in the other. </p><p><strong><em>Autosomal Recessive Limb-Girdle Muscular Dystrophy 17</em></strong></p><p>
Gundesli et al. (2010) identified a homozygous 9-bp deletion in exon 1f of the PLEC1 gene (601282.0010) in affected members of 3 Turkish families with autosomal recessive limb-girdle muscular dystrophy (LGMDR17; 613723), previously symbolized LGMD2Q, without skin involvement. The deletion was found to affect only the 1f isoform of plectin. Muscle biopsy from an affected individual showed significantly (100-fold) decreased expression of plectin isoform-1f mRNA and a 3-fold decrease of the plectin protein. Electron microscopic studies of patient muscle showed empty spaces between the sarcolemma and the contractile elements of the sarcomere, separation of membranes, loss of myofibrillar organization in some areas, and misalignment of the Z lines. These findings suggested that PLEC1 isoform-1f is a sarcolemma-associated protein with a specific role in skeletal muscle, and that lack of this isoform results in disruption of the myofiber without affecting other tissues. </p>

<strong>Genotype/Phenotype Correlations</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Natsuga et al. (2010) examined plectin expression patterns in the skin of 3 patients with EBSPA and 6 with EBSMD, all of whom carried mutations in the PLEC1 gene. In EBSPA, expression of all plectin domains was found to be markedly attenuated or completely lost. In EBSMD, the expression of the N- and C-terminal domains of plectin remained detectable, although the expression of rod domains was absent or markedly reduced. The findings suggested that loss of the full-length plectin isoform with residual expression of the rodless plectin isoform leads to EBSMD, but that complete loss or marked attenuation of both the full-length and rodless plectin isoforms underlies the more severe EBSPA phenotype. In addition, the majority of EBSMD-associated PLEC1 mutations occurred within the large exon 31 that encodes the plectin rod domain. EBSPA-associated PLEC1 mutations were generally outside of exon 31. </p>

<span class="mim-text-font">
<p>Winter et al. (2015) noted that, in skeletal muscle, the 4 major plectin isoforms, which have distinct N termini, are required for the integrity of myofibers by targeting and anchoring desmin intermediate filaments to Z-disks (isoform-1d), costameres (isoform-1f), mitochondria (isoform-1b), and nuclear and sarcoplasmic reticulum membranes (isoform-1). Winter et al. (2015) found that striated muscle-specific knockdown of Plec1 in mice reduced mitochondrial content and respiratory capacity and altered mitochondrial morphology and position at Z-disk structures in heart and in soleus and gastrocnemius skeletal muscle. Defects in Plec1 -/- muscle increased with age, and gastrocnemius showed the most severe phenotype. Specific knockout of plectin isoform-1b caused severe mitochondrial dysfunction compared with knockout of isoform-1d, with decoupling of mitochondrial networks and mitochondrial enlargement, concomitant with upregulation of the mitochondrial fusion-associated protein Mfn2 (608507). </p>

<p>In a patient with epidermolysis bullosa simplex with muscular dystrophy (EBS5B; 226670), Smith et al. (1996) found a homozygous 8-bp duplication mutation (insertion of the sequence GTGGAGGA) leading to a premature termination codon 14 bp downstream of the insertion. This frameshift mutation was predicted to cause premature termination of translation in the R2C subdomain of the plectin polypeptide within the rod domain predicted to be involved in polymerization. Smith et al. (1996) stated that such a genetic lesion is likely to cause loss of protein expression through nonsense-mediated decay of the predicted 15-kb plectin mRNA.

Immunoblot of cell lysates of HEK293 cells cotransfected with wildtype ITGB4 (147557) and the L319P PLEC mutant showed reduced plectin and beta-4 integrin proteins, suggesting that the misassembled plectin/beta-4 integrin complex enhances protein degradation, resulting in defective hemidesmosome formation. </p>

<p>In 2 Turkish sisters with epidermolysis bullosa simplex and nail dystrophy (EBS5D; 616487), born of consanguineous parents, Gostynska et al. (2015) identified homozygosity for a c.46C-T transition in exon 1a of the PLEC1 gene, resulting in an arg16-to-ter (R16X) substitution present in only the 1a isoform. Quantitative RT-PCR of cultured skin keratinocytes from the sisters showed reduced transcription of 1a compared to controls. Because isoform-1a is not expressed in either striated or cardiac muscle tissue, Gostynska et al. (2015) stated that they did not expect muscular dystrophy or cardiomyopathy to develop in these patients. </p>
