Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PS3PP2PP5_Very_Strong

The NM_019616.4(F7):c.995C>T(p.Ala332Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000401 in 1,612,734 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000915624: Functional analysis of FVII activity in the plasma of a homozygous individual carrying this variant and the second variant, c.11128delC, showed drastically reduced activity. In vivo studies of the p.Ala354Val variant identified decreased activation of FX by variant FVII protein" and additional evidence is available in ClinVar.

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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000915624: Functional analysis of FVII activity in the plasma of a homozygous individual carrying this variant and the second variant, c.11128delC, showed drastically reduced activity. In vivo studies of the p.Ala354Val variant identified decreased activation of FX by variant FVII protein; however, functional studies showed discordant results when evaluating alterations in the variant protein's interaction with activators and cofactors (Toso et al. 2002; Fromovich-Amit et al. 2004; Branchini et al. 2012).; SCV002573746: PS3; SCV004175609: "biochemical functional assay show low FVII activity)" (PP4).

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: 0.36088 (below the threshold of 3.09). GenCC associations: The gene is linked to congenital factor VII deficiency, factor VII deficiency.

PP5

Variant 13-113118668-C-T is Pathogenic according to our data. Variant chr13-113118668-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 12076.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
