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:):

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: This place is a probable branch point but rather VUS (scored 5 / 10). Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BP6: Variant 1-74236083-A-G is Benign according to our data. Variant chr1-74236083-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1583066.Status of the report is criteria_provided_single_submitter, 1 stars.
