Genes affected

F7 (HGNC:3544): (coagulation factor VII) This gene encodes coagulation factor VII which is a vitamin K-dependent factor essential for hemostasis. This factor circulates in the blood in a zymogen form, and is converted to an active form by either factor IXa, factor Xa, factor XIIa, or thrombin by minor proteolysis. Upon activation of the factor VII, a heavy chain containing a catalytic domain and a light chain containing 2 EGF-like domains are generated, and two chains are held together by a disulfide bond. In the presence of factor III and calcium ions, the activated factor then further activates the coagulation cascade by converting factor IX to factor IXa and/or factor X to factor Xa. Defects in this gene can cause coagulopathy. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing to generate mature polypeptides.

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Gene score misZ: 0.31991 (below the threshold of 3.09). Trascript score misZ: 0.24236 (below the threshold of 3.09). GenCC associations: The gene is linked to congenital factor VII deficiency, factor VII deficiency.
• PP5: Variant 13-113118590-T-C is Pathogenic according to our data. Variant chr13-113118590-T-C is described in ClinVar as Pathogenic. ClinVar VariationId is 12090.Status of the report is no_assertion_criteria_provided, 0 stars.
