Genes affected

TNNI3K (HGNC:19661): (TNNI3 interacting kinase) This gene encodes a protein that belongs to the MAP kinase kinase kinase (MAPKKK) family of protein kinases. The protein contains ankyrin repeat, protein kinase and serine-rich domains and is thought to play a role in cardiac physiology. [provided by RefSeq, Sep 2012]

FPGT-TNNI3K (HGNC:):
