Genes affected
CTF1 (HGNC:2499): (cardiotrophin 1) The protein encoded by this gene is a secreted cytokine that induces cardiac myocyte hypertrophy in vitro. It has been shown to bind and activate the ILST/gp130 receoptor. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]
