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:42952): (FPGT-TNNI3K readthrough) Enables protein C-terminus binding activity; protein kinase activity; and troponin I binding activity. Involved in protein phosphorylation and regulation of heart contraction. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

LRRC53 (HGNC:25255): (leucine rich repeat containing 53) Predicted to be integral component of membrane. Predicted to be active in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.24).
