Genes affected

CCN3 (HGNC:7885): (cellular communication network factor 3) The protein encoded by this gene is a small secreted cysteine-rich protein and a member of the CCN family of regulatory proteins. CNN family proteins associate with the extracellular matrix and play an important role in cardiovascular and skeletal development, fibrosis and cancer development. [provided by RefSeq, Feb 2009]

ENSG00000253398 (HGNC:):
