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.

Pathogenic, no assertion criteria provided	literature only	OMIM	Dec 01, 2002	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jun 25, 2020	The p.His408Gln variant in F7 has been reported in 3 homozygous and 3 compound heterozygous individuals with factor VII deficiency and segregated with disease in 2 affected individuals from 2 families ( Katsumi 2000 PMID: 10739380, Shen 2001 PMID: 11260055, Jin 2011 PMID: 21287501, Li 2013 PMID: 23358202, Jin 2015 PMID: 25863091, Wang 2018 PMID: 30208845). It has also been identified in 0.033% (6/18114) of East Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In vitro functional studies provide some evidence that this variant impacts protein function (Katsumi 2000 PMID: 10739380); however, these types of assays may not accurately represent biological function. Another variant at the same codon (p.His408Arg) has been identified in individuals with factor VII deficiency, suggesting that change at this position may not be tolerated. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive factor VII deficiency. ACMG/AMP criteria applied: PM3_Strong, PM5, PP1_Moderate, PS3_Supporting. -
