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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 01, 2012Variant classified as Uncertain Significance - Favor Benign. The 145-10G>A varia nt (CTF1) has not been reported in the literature nor previously identified by o ur laboratory. This variant is located in the 3' splice region. Computational to ols do not predict altered splicing; however, this information is not predictive enough to rule out pathogenicity. Additional studies are needed to fully assess the clinical significance of the 145-10G>A variant. -
