Genes affected

F2 (HGNC:3535): (coagulation factor II, thrombin) This gene encodes the prothrombin protein (also known as coagulation factor II). This protein is proteolytically cleaved in multiple steps to form the activated serine protease thrombin. The activated thrombin enzyme plays an important role in thrombosis and hemostasis by converting fibrinogen to fibrin during blood clot formation, by stimulating platelet aggregation, and by activating additional coagulation factors. Thrombin also plays a role in cell proliferation, tissue repair, and angiogenesis as well as maintaining vascular integrity during development and postnatal life. Peptides derived from the C-terminus of this protein have antimicrobial activity against E. coli and P. aeruginosa. Mutations in this gene lead to various forms of thrombosis and dysprothrombinemia. Rapid increases in cytokine levels following coronavirus infections can dysregulate the coagulation cascade and produce thrombosis, compromised blood supply, and organ failure.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

PM1

In a disulfide_bond Interchain (between light and heavy chains) (size 146) in uniprot entity THRB_HUMAN there are 11 pathogenic changes around while only 1 benign (92%) in NM_000506.5

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 23 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 2.1083 (below the threshold of 3.09). Trascript score misZ: 2.7629 (below the threshold of 3.09). GenCC associations: The gene is linked to congenital prothrombin deficiency, thrombophilia due to thrombin defect.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.98

PP5

Variant 11-46726761-G-A is Pathogenic according to our data. Variant chr11-46726761-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 13312.Status of the report is no_assertion_criteria_provided, 0 stars.
