Genes affected
TJP2 (HGNC:11828): (tight junction protein 2) This gene encodes a zonula occluden that is a member of the membrane-associated guanylate kinase homolog family. The encoded protein functions as a component of the tight junction barrier in epithelial and endothelial cells and is necessary for proper assembly of tight junctions. Mutations in this gene have been identified in patients with hypercholanemia, and genomic duplication of a 270 kb region including this gene causes autosomal dominant deafness-51. Alternatively spliced transcripts encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 29, 2015p.Val1064Leu in Exon 21 of TJP2: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, mole rat and rabbit as well as many other non-mammalian species have a leu cine (Leu) at this position despite high nearby amino acid conservation. In addi tion, this variant has been identified in 41/67664 European chromosomes by the E xome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs19989 2018). -
