Summary

JCAD (junctional cadherin 5 associated, HGNC:29283) is a protein-coding gene on chromosome 10p11.23, encoding Junctional cadherin 5-associated protein (Q9P266).

This gene encodes an endothelial cell-to-cell junction protein. Naturally occurring mutations in this gene are associated with coronary artery disease, late onset alzheimer disease, and emphysema distribution.
