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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TNNI3K protein function. ClinVar contains an entry for this variant (Variation ID: 1460658). This variant has not been reported in the literature in individuals affected with TNNI3K-related conditions. This variant is present in population databases (rs200469447, gnomAD 0.002%). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 12 of the TNNI3K protein (p.Cys12Tyr). -
