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.

Variant summary: F7 c.1165T>G (p.Cys389Gly) results in a non-conservative amino acid change located in the Serine proteases, trypsin domain (IPR001254) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 249480 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in F7 causing Congenital factor VII deficiency, allowing no conclusion about variant significance. c.1165T>G has been reported in the literature in multiple individuals affected with Congenital factor VII deficiency (e.g. Yu_2009, Kwon_2011). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 19601987, 21206266). ClinVar contains an entry for this variant (Variation ID: 12085). Based on the evidence outlined above, the variant was classified as pathogenic. -
