Genes affected

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]

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:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.3781781E-6).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.883 is higher than 0.05.
