dbSNP rs370113173: TNNI3K:p.Arg7Ser (chr1-74235472-A-C) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_015978.3(TNNI3K):c.21A>C(p.Arg7Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000066 in 151,614 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R7G) has been classified as Uncertain significance.

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]

TNNI3K links:

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]
