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]

Collection Method:clinical testing

The 26-12C>G variant in CTF1 has not been previously reported in individuals wit h cardiomyopathy or in large population studies. This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. Howe ver, this information is not predictive enough to rule out pathogenicity. In sum mary, the clinical significance of the 26-12C>G variant is uncertain.
