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]

Ambry Genetics

Mar 22, 2023

The c.2128C>A (p.P710T) alteration is located in exon 22 (coding exon 22) of the TNNI3K gene. This alteration results from a C to A substitution at nucleotide position 2128, causing the proline (P) at amino acid position 710 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
