Gene: CTNNA3 (catenin alpha 3) Homo sapiens
Symbol: CTNNA3
Name: catenin alpha 3
Description: This gene encodes a protein that belongs to the vinculin/alpha-catenin family. The encoded protein plays a role in cell-cell adhesion in muscle cells. Mutations in this gene are associated with arrhythmogenic right ventricular dysplasia, familial 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]
Type: protein-coding
RefSeq Status: REVIEWED
