22170284 While many of the reported ARVC mutations are truncating mutations, the possibly damaging variant found in this family, is a missense alteration affecting a highly conserved residue 506 located in exon 7.
22119253 PKP2 gene upregulation is associated with bladder cancer invasion.
22035158 The authors report on a pedigree of cases involving a mutation in the plakophilin 2 gene that was associated with the development of arrhythmogenic right ventricular cardiomyopathy.
22019812 PKP2 mutations are not specific for arrhythmogenic right ventricular cardiomyopathy and may result in sudden unexpected death with negative autopsy.
21947748 In breast cancer, compared with normal tissue, PKP1 and PKP2 expressions were indifferent (P > 0.05), but PKP3 expression was significantly increased
21378009 PKP2A was shown to be the major isoform expressed in human heart tissue and PKP2B protein was undetectable; results strongly suggest that p.Arg490Trp and other variants located in PKP2 exon 6 may not be disease causing
20864495 Studies identified two mutations in DSG2, four in DSC2, two in DSP, four in JUP and seven in PKP2.
20693980 Adherens junctions connecting cardiac myxoma cells show exactly such general acquisition of Pkp2.
20554761 Data suggest that PKP2 may functionally link RhoA- and PKC-dependent pathways to drive actin reorganization.

19084810 Their expression did not disrupt localization of endogenous PKP2, connexin-43 (Cx43), or desmoplakin (DP). However, we observed reduced abundance of Cx43 after R79x expression.
18662195 Reduced connexin43 expression and localization to the intercalated disk occurs in heterozygous human PKP-2 mutations, potentially explaining the delayed conduction and propensity to develop arrhythmias seen in this disease.
18632414 Mutations in the desmosome genes were identified in four of the five patients (three with a DSG2 mutation and one with a DSP mutation). Five gene mutations were noted in four patients and all mutations were novel (one patient had a DSG2 double mutation).

17521752 The present study adds to the growing body of evidence that plakophilin-2 missense mutations represent a major inherited cause of arrhythmogenic right ventricular dysplasia (ARVD) in patients of Finnish ancestry.
17041889 Novel homozygous mutation in PKP2 (c.[2484C>T]+[2484C>T]), which is predicted to be translationally silent, produced an alternatively spliced variant and Arrhytmogenic right ventricular dysplasia.
17010805 PKP2 mutations in a group of families with ARVD/C have both reduced penetrance and variable expressivity. Gender may have an influence on penetrance of PKP2 mutations, with male mutation carriers more likely to develop specific phenotypic manifestations
16876743 Premature truncation of the plakophilin-2 protein appears to be the predominant mechanism whereby PKP2 mutations elicit the arrhythmogenic right ventricular cardiomyopathy phenotype.
16567567 PKP2 mutations can be identified in nearly half of the Dutch patients fulfilling the arrhythmogenic right ventricular dysplasia/cardiomyopathy(ARVC)criteria.
16549640 PKP2 mutation in arrhythmogenic right ventricular dysplasia/cardiomyopathy(ARVD/C) correlates with earlier onset of symptoms and arrhythmia. Patients experience implanted cardioverter/defibrillator(ICD) interventions irrespective of classic risk factors.
