Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the JUP gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Common junctional plaque protein. The membrane- associated plaques are architectural elements in an important strategic position to influence the arrangement and function of both the cytoskeleton and the cells within the tissue. The presence of plakoglobin in both the desmosomes and in the intermediate junctions suggests that it plays a central role in the structure and function of submembranous plaques. Acts as a substrate for VE-PTP and is required by it to stimulate VE- cadherin function in endothelial cells. Can replace beta-catenin in E-cadherin/catenin adhesion complexes which are proposed to couple cadherins to the actin cytoskeleton (By similarity). {ECO:0000250}.
• Disease: DISEASE: Naxos disease (NXD) [MIM:601214]: An autosomal recessive disorder characterized by the association of diffuse non- epidermolytic palmoplantar keratoderma with woolly hair and cardiac abnormalities such as dilated cardiomyopathy and arrhythmogenic right ventricular dysplasia. {ECO:0000269|PubMed:10902626}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Arrhythmogenic right ventricular dysplasia, familial, 12 (ARVD12) [MIM:611528]: A congenital heart disease characterized by infiltration of adipose and fibrous tissue into the right ventricle and loss of myocardial cells, resulting in ventricular and supraventricular arrhythmias. {ECO:0000269|PubMed:17924338, ECO:0000269|PubMed:20031617}.
